PREFACE
To give effect to a Recommendation adopted by the Second
Inter-Governmental Conference on Reciprocal Arrangements respecting Safety in the Loading and Unloading of Ships, held in
London in July 1935, the International Labour Office decided, in
1937, to publish a monograph on Safety in Dock Work. After consultation with the members of the Correspondence Committee on
Accident Prevention, the Office appointed Mr. C. MÖRZER BRUYNS,
Chief Port Labour Inspector of Rotterdam, as "rapporteur" to
prepare a first draft of the technical part of the monograph.
Mr. Mörzer Bruyns went to work with such zeal and alacrity
that the preliminary text of Part I was completed and submitted to
the I.L.O. in exactly three months.
In conformity with the established practice, the next steps
should be revision of the draft by the I.L.O., translation into French,
and submission to the Correspondence Committee on Accident
Prevention for discussion, final drafting and adoption.
The revision and translation of the text proved- to be a difficult.
task, and when the draft was finally ready for discussion, further
progress proved to be impossible, for financial and other reasons.
Then the war broke out and the monograph had to be put aside.
However, the International Labour Office gradually resumed its
activities after the transfer of its working centre from Geneva to
Montreal in September 1940 and the preparation of Mr. Mörzer
Bruyns' text for publication was one of the first tasks to be taken
in hand again. In the summer of 1942 the draft was distributed
to all the members of the Correspondence Committee whom the
Office could reach, and it was subsequent y discussed at a meeting
of the Canadian and United States members of the Committee,.
held in New York in December of that year. The Committee
suggested certain small changes in the draft, and unanimously
expressed the wish that:
"in view of the very considerable value of the material it contains, this monograph should be issued by the International Labour
Office as quickly as it can be prepared for publication".

ii

SAFETY IN DOCK WORK

Although the Office fully recognised the desirability of having
the monograph published at the earliest possible date, it was
considered essential to obtain the views of at least some of the
European members of the Committee; owing to difficulties of
communication, however, this was bound to cause considerable
delay in publication.
The International Labour Office is greatly indebted to Mr.
Mörzer Bruyns for his excellent preparatory work; it regrets that
events since the spring of 1940 have compelled it to complete the
monograph without benefiting further from his great experience
in all matters concerning dock work, and hopes to count him among
its external collaborators in this field in the future. The Office also
wishes to express sincere thanks to the members of the Correspondence Committee who assisted in the revision of the monog r a p h , and particularly to Mr. G. STEVENSON TAYLOR, London,
Mr. Cyril AINSWORTH, New York, Mr. Swen KJAER, Washington,
D.C., and Mr. R. B. MORLEY, Toronto, who submitted valuable
material for inclusion in the text.

Safety in Dock Work

INTRODUCTION
The scope of dock labour is so wide that it is impossible to deal
in a monograph of reasonable length with all the risks to which
dock workers may be exposed, and not much more than a superficial account of some of the safety problems of stevedoring can be
attempted here.
These risks may arise from different causes and can be classified
according to the place of work as follows:
I. On board sea-going and inland waterway vessels.
(a) Means of access to the hold and communication in the hold ;
(b) Hatches and hatch coverings;
(c) Lifting machinery, including masts, derricks, standing and
running rigging;
(d) Equipment used for loading and discharging;
(e) Methods of loading, discharging, stacking and unstacking,
stowing and unstowing, etc.;
(/) Electricity, e.g. lighting on deck and in the holds, and
electrical hoisting machines.
Some of these subjects are large enough for separate monographs.
Another monograph could be written on the dangers to which
dock workers are exposed when handling 1 :
1. Explosives;
2. Compressed, liquefied and dissolved gases;
3. Substances which become dangerous by reaction with water
or air (e.g. ferrosilicon, calcium carbide);
4. Substances giving off flammable vapours, which, moreover,
are in many cases poisonous;
5. Corrosive substances (e.g. caustic potash and soda, acids);
6. Poisonous substances (e.g. ammonia, ethyl fluid) ;
7. Substances liable to spontaneous combustion (e.g. celluloid,
copra, films, matches, sulphur, cotton).
One of the most difficult problems is constituted by the dust
given off during the processes, e.g. when loading and unloading
1
The list follows the classification adopted in the Report (issued in 1933) of
the Departmental Committee appointed by the British Board of Trade to consider
the existing Board of Trade Memorandum on the "Carriage of Dangerous Goods
and Explosives in Ships".

SAFETY IN DOCK WORK

fertilisers such as ground basic slag, or various ores, or pitch. In
this connection the spores of the anthrax-bacillus may be mentioned
as a serious danger; and as a lesser danger, acroleine evaporated
from whale oil.
II. Floating cranes, grain elevators, bunkering appliances, shear
legs, etc.
The dangers menacing the workers here are sometimes of another
nature than those mentioned under I, but it does not seem necessary to give a separate account of them.
III. Docks, wharves, quays and sheds, including all lifting
machinery and transport appliances ashore.
A valuable paper could be written on the safety problems ashore,
•e.g. fencing of approaches over docks, wharves or quays, rescue
from drowning, measures against fire, first aid, protection against
lightning, prevention of accidents caused by wagons and trucks,
or occurring in and on sheds, etc.
IV. Means of access to or from the vessel or other workplaces.
These include accommodation ladders, gangways, wooden and
rope ladders, and tugs and other boats used for the transport of
dockers by water.
At all events, many shipbuilding details have to be taken into
account, and an efficient inspection service must supervise enforcement of the regulations and calculate the stresses in the loading
and unloading equipment.
A treatise on safety and welfare generally, including the influence of mechanisation, night work, the length of working hours,
meteorological circumstances, occupational skill, etc., would be a
valuable contribution to the subject now under consideration.
Considerations of space, however, have made it necessary to
restrict the scope of the monograph to the more important problems
of a purely technical character and only a short chapter has been
added on the various diseases and dangerous substances to which
the docker is exposed, and which sometimes cost him his life.
Some examples of national regulations for the prevention of •
accidents in dock work, together with international regulations,
will be found in Part II.
It is hoped that the present monograph, notwithstanding its
limitations, will serve a useful purpose and will help to bring about
a wider study of the manifold problems of safety in dock work.

CHAPTER I

GENERAL MEASURES OF PROTECTION FOR HOISTING
AND TRANSPORT MACHINERY USED IN
LOADING AND UNLOADING SHIPS
§ 1—Fencing of Dangerous Parts
Although most of the machinery and equipment used in the
loading and unloading of ships is of a special type, different from
that used in industry generally, there are certain general rules of
protection which are applicable in both cases.
Thus, as with industrial machinery in general, hoisting and
transporting appliances used on board ship and in docks, e.g.
winches, derricks, cranes, conveyors and transporters, must be
provided with proper fencing or other adequate protection at all
points where there is a risk of injury to the men in charge of machinery or to other persons employed in loading or unloading. All
dangerous machine parts, such as cog-wheels, chain or friction
drives, gears, shafting, etc., should either be completely enclosed
or otherwise adequately protected to prevent any person from
coming into accidental contact with them. The guards must not
be removed while the machine or apparatus is in use; if they have
to be removed they must be replaced as soon as possible, and in
any case before the machines or apparatus are again taken into
normal service.
As a general rule, it can be said that the types of enclosures or
guards ordinarily used in industry for similar purposes afford
sufficient protection for the installations that we are dealing with
here.
On steam-driven winches and other machinery the steam pipes
and all other steam-carrying or steam-heated parts must be adequately insulated or otherwise enclosed, so as to prevent burns.
Where electrically driven winches or other appliances are used,
care must be taken that all live electric conductors and other
current-carrying parts are protected in conformity with the special
regulations concerning electrical installations.

4

SAFETY IN DOCK WORK

§ 2—Safe Means of Access
Safe means of access should be provided for all drivers' platforms on cranes and other hoisting or transporting appliances, and
all such platforms and all other places on which crane operators,
winch drivers or other persons have to work, or over which they
have to pass in the course of their work, should be provided with
adequate railings so as to prevent persons from falling.
§ 3—Protection against Accidental Descent of Loads
All cranes, winches and other lifting machines should be provided with efficient brakes and with any other safety devices required to prevent accidental descent of suspended loads. This
general rule is of even greater importance in loading and unloading
operations in docks than at many other workplaces where hoisting
operations are being carried out.
Brakes and other devices installed for this purpose should be of
sound construction and of sufficient strength to hold safely the
heaviest load permissible for the crane or winch to which they
belong. All such devices should be kept in good working order and
properly examined and tested at regular intervals.
§ 4—Safety Factors
Since in many of the following chapters strength of materials
will be discussed, it may be useful to include here an enumeration of
safety factors for hoisting equipment.
In connection with the adoption of the (revised) Convention
(No. 32) concerning the protection against accidents of workers
employed in loading or unloading ships (see Part II), the International Labour Conference, at its 1932 Session, also adopted a Recommendation requesting the Governments of the principal countries concerned t o make arrangements with a view to securing reasonable uniformity in the application of the Convention.
In pursuance of this provision, meetings of representatives of a
number of maritime countries were held in London in 1932 and 1935.
The matter of safety factors was among those dealt with by these
meetings. The meeting in 1935 unanimously adopted a recommendation on this subject, as follows1:
Safely Factors.
In view of the importance of the provision by manufacturers of adequate
safety factors in their designs of hoisting machines and gear, manufacturers
'The final conclusions of this meeting were published, in extenso, in Industrial
Safety Survey, Vol. XII, No. 2, Mar.-Apr. 1936, pp. 42-45.

GENERAL MEASURES OF PROTECTION

should be given some guidance in this matter. For this purpose the adoption
of the following minimum safety factors is proposed without prejudice to account
being taken of the provisions and measures recommended by National Standards
Associations:

(a) when the safe working load is 10 tons or less
(6) when the safe working load is over 10 tons

It must be borne in mind that these figures are given as minima,
each country wishing to fix higher factors being authorised to do so.

CHAPTER II
HOISTING MACHINES AND GEAR ON BOARD
Article 9 of the Convention (No. 32) concerning the protection
against accidents of workers employed in loading or unloading ships
(revised 1932)1 begins with the general provision that:
Appropriate measures shall be prescribed to ensure that no hoisting machine,
or gear, whether fixed or loose, used in connection therewith, is employed in t h e
processes on shore or on board unless it is in a safe working condition.

Everyone who has to judge the safe working condition of some
part or other of ship's gear has naturally to be acquainted with the
stresses acting in that part when loading or unloading, even if
appropriate safety regulations exist.
It is not sufficient to accept the safe working load indicated by
someone who considers himself competent, or to be satisfied with a
safe working load found in a certificate: the responsible person
should be able to verify the figures, either by calculating the stresses
directly or by using the graphical method.
Such a procedure has proved to be necessary wherever a serious
examination has been made. The unreliability of many so-called
safe loads may be illustrated by the following table, relating to 12&
ships in the port of Rotterdam. Of course this table only mentions
cases that happened to be noticed during inspections; it should by
no means be assumed that it gives a list of all wrongly indicated
safe working loads.
The 128 ships in question were of 13 different nationalities.
Several vessels referred to in this table were in thé possession
of certificates, issued by competent persons, to the effect that the
derricks could be used up to the weight'marked upon them.
In no less than 26 cases these certificates proved to be of no value ;
the safe working loads had to be reduced considerably, and in some
cases permission could not be given to use the gear at all.
It is thus evident that certificates often cannot be relied upon,,
and hence it is not sufficient for the supervising persons to read the
certificates; serious investigation and verification of the safe load
are necessary.

* Derrick split: working not allowed.
** Derrick rotten: working not allowed.
*** Mast broke when hoisting a load of 900 kg.

As a matter of fact, the scientific training of the persons who
have to judge the safe loads in the light of the approved safety
factors should be sufficient to enable them to carry out these duties.
Even persons considered to be competent often misjudge the
stresses in the gear, if they have to base their judgment on what
they observe and have no occasion, or do not know how, to calculate them. A faulty estimate of these stresses is most likely if
the derrick is much longer than the mast; examples of such cases
are given in figs. 1 and 2.
This is not the place for a detailed discussion of stresses, b u t a
few general remarks may be useful. Given the safety factors, the
dimensions of the different parts of the gear can be fixed when t h e
stresses are known. Calculation of the stresses in the gear, however,
is a very difficult task, which should be performed by naval architects, standardisation committees, classification bureaux and the
like. For practical use tables have been compiled that greatly
facilitate verification. The most elaborate of these tables are to be
found in the Vorschriften über Lade- und Lösch-Einrichtungen of the
German See-Berufsgenossenschaft, in the Grundsätze für die Prü-

Report of the Netherlands Committee for Loading and Unloading
Gear, etc.
As compared with calculation, however, the graphical method
enables the stresses to be computed with relative ease. Below are
some simple examples of this method for running rigging, showing
how greatly the stresses vary according to the construction of the
gear and the angle of the derrick to the horizontal.

SAFETY IN DOCK WORK

In the first series (figs. 3, 4, 5) three derricks of different lengths
are fastened to the same mast at an angle of 30° and the same load
is applied. The stresses in the single span wire rise from 3,000 to
6,264 kg, and the stress on the span block and on the fastening
point of this block to the mast, from 5,200 to 8,440 kg.

In the second series (figs. 6, 7, 8) the angle is 15°. With a 3-ton
load, the stress in the single span wire rises from 3,904 to 7,500 kg
and on the span block, from 7,000 to 11,146 kg.
Here the weight of the derrick with cargo block etc. (estimated
at 40O kg) is taken into account; this should also have been done in
the first series, but was omitted in order to bring out the theoretical
stresses induced by the load.

11

HOISTING GEAR ON BOARD

In the third series (figs. 9, 10, 11) the stresses are given for 3
methods of hoisting with the same derrick at the same angle.

Fig. 9

Fig. 10

Fig. 11

It is worth mentioning that in most cases the stresses in the
span wire, span blocks and fastening points are influenced only by
the weight of the load ; the rig or method of hoisting, e.g. by single
or double gear or by fastening the upper end of the runner to the
cargo block or to the derrick, etc., will have an influence on these
stresses only when the cargo runner is taken parallel to the span wire.
However, the stresses in cargo runner, derrick-head cargo
block; derrick-heel lead block and fastenings depend to a large
extent on the manner of hoisting.
In principle, the influence of the weight of the derrick, cargo
block, etc., should not be neglected and usually half this weight is
taken into account. It can be considerable for heavy gear {e.g. the
weight of a derrick pole with cargo and guy blocks and steel wire
f o r a 50 top derrick may amount to 6,000 kg). Moreover the fric-

12

SAFETY IN DOCK WORK

tion of the sheaves in the blocks has to be considered, and this is
generally estimated at 5 per cent, of the load per sheave.
With multiple-sheave blocks especially, the friction can be very
considerable, and safety may be seriously endangered if no special
attention is paid to it.
In this connection it may be useful to draw attention to the fact
that in the case of a derrick rigged with the cargo runner parallel
to the span, the greatest pull developed in the span wire during
hoisting or lowering occurs, due to frictional forces developed in
the runner blocks, during lowering. This may be illustrated by the
following example :
A load of 50 t is being steadily raised and lowered by a set of
blocks, having twelve parts of rope, connected to a boom having
the derrick ratio of 1. The cargo runner is taken parallel to the
span. When the derrick is at 45° to the horizontal, the tension in
the span rope due t o the static weight of 50 t is 38.5't. In this case,
the pull in the span rope can be calculated as follows: (1) assuming
no friction, and (2) assuming a friction of 5 per cent, per sheave.
(1) Assuming no friction.
rn f
Pull in cargo runner (hoisting or lowering) =—rr— = 4.2 t.
Hence, since the cargo runner is parallel to the span wire and
therefore relieves the pull in the latter, the pull in the span
rope (hoisting or lowering) = 38.5 t — 4.2 t = 34.3 t.
(2) Assuming 5 per cent, friction per sheave.
Pull in cargo runner during hoisting = 6.5 t
Pull on span wire = 38.5 t — 6.5 t = 32 t
Pull in cargo runner during lowering = 3 t
<
Pull on span wire = 38.5 t — 3 t = 35.5 t
Hence the pull in the span wire is approximately 10 per
cent, greater when lowering the load than when raising it.

HOISTING GBAR ON BOARD

The subject of blocks is dealt with
in more detail in Chapter VII.
To give an idea of the very intricate
problem of the stresses in standing
rigging it may be useful here to give
an extract from the abovementioned
Report of the Netherlands Committee
for Loading and Unloading Gear, etc.
(figs. 12,13). Let:

Table II, on page 12, shows, for

ropes fastened at a moderate distance one from another.
The influence of W, L and B is evident. The situation will of
course change fundamentally when stays are used, but the table
gives a good idea of the stresses to which main ropes are exposed.
Moreover, it is a serious warning against working with loosened
main ropes and stays, which is done rather frequently, and has been
the cause of several casualties.
In this connection it is worth mentioning that during the years
1932-1936 the Netherlands Port Inspectorate noticed 23 cases in
which a mast collapsed. This number, of course, only covers the
cases known to the writer ; the causes are shown in the following table :

SAFETY IN DOCK WORK

Naturally, very many other problems have to be solved, e.g.,
the resistance of masts and derricks to crushing stresses, and
the safe working load of wires, rigging screws and fastening points.
Generally speaking, standardisation committees, classification
bureaux and manufacturers are now giving very useful indications
on these points.
Lloyds Register Rules, for instance, require the scantlings of
the masts to be in accordance with table 47 of these Rules and
these scantlings are considered suitable for the support of average
equipment of derricks of normal outreach, provided that the staying
of the masts is efficient. Shrouds and stays are required to conform,
in number and size, to the specifications in tables 48 to 57 of the
Rules.
It is not very easy to devise a method for the calculation of the
stresses in the guys, which are generally determined by practical
means. The stresses may become very high, especially when working with fixed derricks and coupled runners (with inner and outer
tackle). 1
For this method special regulations have been issued in some
countries.
The Vorschriften über Lade- und Lösch-Einrichtungen auf deutschen Seeschiffen issued by the See-Berufsgenossenschaft in 1935 contain the following regulation:
§65
3. T h e use or two ñxed derricks with runners shackled together for loading
and unloading is only allowed when the eyes on the outer guys of the derricks,
and the outer guys themselves are strong enough.

and the Netherlands Committee for Loading and Unloading Gear
on Board Sea-going Ships stated in their report of 1932 (Part I),
section 20:
When cargo gear not especially constructed for this purpose is used for
loading or unloading with inner and outer tackle, the load shall not exceed i
of the load on which are based calculations of the relevant part of the gear assuming normal use with slewing derricks.
The guys shall have a t least the actual breaking strength mentioned below.
Care shall be t a k e n that, for cargo gear, constructed for loading or unloading
with inner and outer tackle, and for which sufficient directions for the fitting up
and the fixing of the guys are carried on board, the stresses in the derricks and
spans do not exceed the maximum values for the most unfavourable working
position of the derricks.
No guy shall be subjected to a heavier load than two sevenths of the actual
breaking strength.
1
In Great Britain, this arrangement is generally known as the "Union Purchase" rig.

HOISTING GEAR ON BOARD

This mode of working is only allowed for single rope and for loads of 2 tons
c
or less.
Moreover, when determining the length of the derricks consideration must
be given to the capacity of the winches, the height of the bulwarks, and any other
factors that may influence the stresses in the gear, and the dimensions and the
weight of the loads to be worked.

As may be inferred from various publications it is generally
accepted that when working with heavy loads the safety factor may
be lower than when working with light loads. This is quite reasonable because, when a heavy load is to be hoisted, everything is
especially examined beforehand, the work is executed very
carefully and all shocks are avoided; the higher officers of the
ship and of the stevedoring company are present. All these measures are not taken and cannot be taken during ordinary work. In
addition, the loose gear for heavy derricks is generally stowed away
and mounted when necessary. It is used only on a few occasions
during its lifetime, so that practically no wear and tear is caused.
Moreover, it is almost impossible from a practical point of view
to supply a ship that is fitted out with gear for heavy loads, with
stays, etc., calculated for the highest safety factor, since these parts
of the gear would become too clumsy, and in the light of the above
considerations it does not seem necessary to give this gear the same
relative strength as the ordinary gear, which is used under quite
different circumstances.
Profound ignorance reigns all over the world as to the stresses in
running and standing rigging; this has led to many accidents, and
it therefore seems necessary to give more instruction in the subject.
Experience has shown that visual demonstration is of great
value. This can easily be done by means of an apparatus consist-

16

SAKBTY IN DOCK WORK

Fig. 14

Fig. 15

HOISTING GEAR ON BOARD

17

ing of complete loading and unloading gear of small dimensions,
and allowing the stresses on each part to be read on small spring
balances. An illustration of such an apparatus is reproduced in
fig. 14.
By this means, not only officers and cadets of the mercantile
marine, but also persons in charge of stevedoring operations may
learn much about this difficult subject, the importance of which
up till now has not been properly appreciated by those concerned .
It must also be remembered that, on vessels, theplatformon which
the hoisting machinery is built is not stable. This is not of much
importance when general cargo is loaded or unloaded on large ships,
unless the ship already has a list. Smaller ships may easily list
over if the load is off the centre line, and with heavy loads the inclination may become very considerable, varying to a large extent
with the stability of the ship. The photograph in fig. 15 was taken
when a lighter of 195 tons was hoisted on board by means of the
ship's gear; the angle with the horizontal rose to about 14°. Constructors as well as users of gear must not overlook the possibility
of inclination.
Interest in rigging stresses has increased lately and in Great
Britain for instance, two instruments have been constructed which
enable the stresses to be read without calculation.
Another cause of accidents, which may usefully be discussed at
this point, is that due to the closing up of a derrick on which the
cargo runner is rigged parallel, or nearly so, to the span wire. The
derrick, with its load, suddenly swings vertically towards the mast
supporting it.
Simply, this matter may be considered as follows:

equals the weight lifted. Now,-if in such a case the cargo runner
is parallel to the span wire, it is clear that the derrick would be
on the point of closing up if there is only one part of rope in the
runner. It will be seen, therefore, that in the case of a derrick in
CB
which the derrick ratio . r is approximately 1.4 (fig. 16) the derrick is on the point of closing up when at an angle of 45° to the
horizontal, if the cargo runner (one part of rope) is taken parallel
to the span rope and would close up at all angles over 45°.
The following example illustrates a handy method of readily
ascertaining the critical angle at which a derrick is on the point of
closing up.

Fig. 17

ABC (fig. 17) represents a derrick having a derrick ratio of 1.1.
The cargo runner, rigged parallel to the span, consists of four parts
of rope. To find the critical angle to the horizontal at which the
derrick will be on the point of closing up, draw de vertically to
represent the load W. Set off ef parallel to BA and since there are
four parts of rope in the runner, make ef equal to one quarter of de_

HOISTING GEAR ON BOARD

19

Join fd and draw/g a t right angles to de. Then, the angle <¡>, which
measures approximately 77°, is the critical angle and it follows that
at any greater angle to the horizontal than this the derrick will
close up.
Using the same method it may be shown that for a derrick
having a ratio of 1.4 and two parts in the runner, the critical angle
is about 76° and that in the case of a derrick with a ratio of 0.8 the
critical angle with one part of rope in the runner is approximately
24°, and with two parts, 60°.
In short, it may be demonstrated that the smaller the derrick
ratio and the smaller the number of ropes, the greater is the risk
of the derrick collapsing when the runner is rigged parallel to the
span.
To prevent such an occurrence, the rig should be such as to
give an ample margin of safety, especially as the effect of friction
in the blocks is to increase the pull in the runner and therefore
lessen the angle to the horizontal at which the derrick will close up
when in use.
In addition to the precautions against closing up, measures
must also be taken to prevent derricks from being accidentally
lifted out of their sockets or supports. Occurrences of this kind may
lead to very serious accidents and every derrick should therefore
have its foot adequately secured, so that it can only be lifted out
of the supports when this is necessary for the examination, repair
or replacement of the derrick.

CHAPTER III
CRANES, ETC., ASHORE AND ON PONTOONS
AND LIGHTERS
For these hoisting machines the same general rules are applicable as for those in Chapter II. Hence in the countries ratifying
the Convention (No. 32) concerning the protection against accidents
of workers employed in loading or unloading ships (revised 1932)',
appropriate measures must be prescribed for these machines also,
in order to ensure a safe working condition.
Generally speaking, great differences exist between hoisting
machines on ships and those ashore (floating cranes, etc., included) 1 ,
so that very little of what has been said in Chapter II is applicable
to the latter. These two kinds of hoisting machines are built by
different manufacturers and almost the only common characteristic is that both types hoist and lower goods.
Moreover, the constructor of a floating crane has to solve
several problems that do not enter into consideration for cranes
ashore, because a pontoon or a lighter does not form a stable platform but tilts and swings under the movement of the load.
The national regulations on lifting machinery are as a rule of a
very general character:
(1) Section 18 of the British Docks Regulations, 1934, contains
the following provision:
All lifting machinery shall have been tested and examined by a competent
person in the manner set out in the schedule to these Regulations before being
taken into use.

This requirement is followed by detailed rules but nothing is
said about the construction itself.
(2) The German Unfallverhüiungsvorschriften der Grosshandelsund Lagerei-Berufsgenossenschaft, Ausgabe 1933, give the following
regulations in Chapter V I I :
§11. Cranes shall be built in accordance with the accepted technical rules.
§13. The material, construction and calculation of the bearing parts shall
be in accordance with the accepted technical rules.
1

See below, p. 112.

STRESSES IN CRANES

21

More details follow, but these are not closely concerned with
the construction itself.
(3) In the Netherlands the present Stevedoring Safety Decree
prescribes in Section 7 that at places where stevedoring operations
are carried on, cranes, etc., shall be in good condition. Then come
some detailed regulations including Section 16, which requires that,
if necessary and possible, tests shall be made and repeated periodically.
Similar regulations may be found in other countries, but it is
evident that nowhere are there specific official regulations as to
design and construction. In a few countries the rules of semiofficial institutions are applied.
Before going into these rules it will be convenient to classify
the machines concerned, as follows:
(a)
(b)
(c)
(d)
(e)
(/)

cranes;
bridge cranes;
coal tips;
grain elevators;
bunker appliances;
shear legs.

The dock appliances named under (a), (&), (d), (e), and (/) are
found ashore as well as mounted on pontoons, while coal tips are
naturally built on the quay.

Fig. 18

22

SAFETY IN DOCK WORK

In order to give an idea of the complexity of the problem here,
illustrations are given of shear legs (fig. 18) and a floating bridge
crane with the arm moving horizontally (fig. 19).

Fig. 19

Modern machines ashore are as a rule driven by electricity,
but floating appliances are generally driven by steam; hydraulic
and hand-operated machines, though still in use, are obsolescent.
The safe working load of the machines amounts to from one
ton or less to several hundred tons. An idea of the enormous masses
of material that may be needed for crane construction may be
gained from the following particulars of a 30-ton (grab with contents) bridge crane, used as a transporter for ore and coal:

the whole mounted on 48 wheels.
In view of the very difficult problems to be solved it is evident
that the calculations of the working stresses in crane structures
must be left to the constructor, who, however, should take general
safety rules into consideration.

STRESSES IN CRANES

23

Probably in consequence of crane accidents, in some countries
semi-official institutions have taken the initiative in framing more
detailed regulations and it seems useful to reproduce here some of
their requirements.
The British, (B.S.I.) and the German (D.N.A.) Standards
Institutions have gone rather far in making specifications, and a
committee of the Netherlands Standardisation Institution (C.N.B.)
has also been at work in this field.
While the B.S.I, have retained safety factors as a prominent
feature of their regulations, the D.N.A. have limited themselves
to prescribing the allowable working stresses.
The B.S.I, specifications read:
The crane shall be so designed and constructed t h a t when it is working under
service conditions.the stress induced in any part shall not exceed either (a) the
breaking stress of the material divided by the specified factor of safety or (b)
the allowable working stress specified hereafter.

And also:
The factor of safety for all parts of the crane structure shall not be less than
5, except when another factor or a maximum allowable working stress is . . .
specified . . . This factor and the allowable working stresses provide for impact
and inertia.

Maximum allowable stresses are specified for parts in tension,
parts in compression, parts in shear and for bearing areas, and moreover for bolts and screws other than those used in crane structures,
while for wire ropes and gearing higher safety factors are prescribed.
The D.N.A. gives several tables for the allowable stresses and
in general goes more into detail than the B.S.I., while both give
instructions as to material, testing (they both advise testing with
25 per cent, overload), brakes, fencing, atmospheric influences,
danger of collapsing, etc.
Both institutions draw a clear distinction between cranes for
heavy duty and other cranes; the B.S.I, recommends higher factors
of safety with proportionately lower working stresses for cranes
intended for specially heavy duty and/or on which grabs are employed, while the D.N.A. puts cranes working with grabs in the
highest danger classes.
. Generally speaking, the D.N.A. has treated the subject more
scientifically, and the B.S.I, more practically, including, moreover,
some provisions as to load indicators, ropes, hooks, swivels, painting, etc.
The use of cranes with grabs nearly always, and, in general cargo,
often, causes severe shocks. Special consideration should also be

24

SAFETY IN DOCK WORK

given to the particular working conditions prevailing when beginning to unload ore and coal, when the grabs may automatically
fill themselves as full as possible, and also to the lifting out of the
beams, and the trailing of cargo from under the decks. In.view of
all these contingencies the construction should receive very careful
attention.
Particular care should be taken with the means of anchoring
to rails, platforms and the like and to the counterbalancing of the
weights, for several severe accidents have occurred owing to the
collapse of cranes and loading bridges, caused by storm and wind
stresses.
The following photograph (fig. 20) gives an idea of such a calamity
and of the dangers to which it exposes the dockers.

STRENGTH OF SLINGS. INFLUENCE OF THE ANGLE

It is the merit of G. STEVENSON TAYLOR to have drawn the
attention of practical users to the relation between angle and
tension in sling legs in 1915 in his Memorandum on Chains and
Other Lifting Appliances (reprinted 1930); and in several other
countries publicity has since been given to the dangers latent in
sling angles. Notwithstanding all educational efforts, however,
much ignorance still exists on the subject.
Stevenson Taylor's Memorandum contains several tables and
diagrams. The table reproduced below clearly shows the effects of
angular changes.

SAFETY IN DOCK WORK

Although the sizes of chains given in this table range from
%s in. (5 mm) to 2 x/¿ m - (65 mm), it is strongly recommended
that chains made from iron less than %, in. (8 mm) should not
be used for lifting purposes, because they are more liable to overloading and to damage than chains above this size.
The safe working loads given in the table are based on the formula:
S.W.L. (tons) = 6 d2
where d is the diameter in inches of the iron in the chain link. Where
there is any special risk to life or limb a safe working load of not
more than 5 d2 should be adopted; where chains are subject to
shock or heavy wear, or work over pulleys, or where links are liable
to be bent or indented by severe local pressure, as where a single
sling is reeved ,¿mnd a load having a hard irregular surface, the
safe w o r k ^ g load should not exceed 3.5 d2.
The German Standards Association (D.N.A.) has issued a pamphy t (DIN 685, 2nd edition, October 1935) on tested chains; the
following is an extract from one of the tables (p. 4) :
Angle between the legs

Safe working load per leg
a5 percentage of the maximum

A note indicates that with an angle between the legs larger than
120°, the highest safe working load allowed is only 25 per cent, of
that for an angle of 120° and that consequently the angle should not
exceed 120°.
Several chain manufacturers and also the Association of Belgian
Manufacturers for the Prevention of Industrial Accidents (Association des industriels de Belgique pour la prévention des accidents du
travail) have issued pamphlets drawing attention to the danger
dealt with here, sometimes with diagrams applicable to different
angles between the legs. Much useful information on chain slings
and the slinging of loads is also given in a safety pamphlet bn "The
Use of Chains and other Lifting Gear", issued by the Home Office,
London. 1 As a rule all warnings are limited to chains, although
the same danger exists when steel wire or fibre rope is used; it
should be noted, however, that some regulations {e.g. the British
Docks Regulations, 1934) require the same precautions to be taken
for wire rope slings as for chain slings , whether used singly or with
multiple legs.

STRENGTH OF SWINGS

27

Chain slings should never be shortened by tying knots in them
and care should always be taken to see that the slings are not
damaged or deformed by coming into direct contact with sharp
corners of heavy loads of hard material.
It is interesting to note that in Article 11 (7) of the Convention
(No. 32) concerning the protection against accidents of workers
employed in loading or unloading ships (revised 1932)1 there is the
following provision:
When the working space in a hold is confined to the square of the hatch, and
except for the purpose of breaking out or making up slings,
(a) hooks shall not be made fast in the bands or fastenings of bales of cotton,
wool, cork, gunny-bags, or other similar goods;

' It is evident that this prohibition is the result of bad experience
with breakages of bands or other fastenings. Although in many cases
these binders are intrinsically more than strong enough for hoisting
the bales with hooks made fast in them, the angle between the
parts of the binder on either side of the hook may be such as to
increase the tension in these parts very considerably when a bale
is hoisted in this way.
An example may illustrate this (fig. 21). Bales of compressed
wool of a weight of 450 to 500 kg were fastened with iron strips of
a width of 32 and a thickness of 2 mm, provided with two holes
in order to secure the ends with a pin or rivet, so that the cross
section at the weakest place amounted to 50 mm 2 . If the allowable
stress on this iron is taken at 6 kg/mm 2 , the safe working load of
one strip stretched between the ends may be estimated at 300 kg,
the breaking strength being about 1,500 kg. As two hooks were

160°

Fig. 21
1

See below, p. 119.

28

SAFETY IN DOCK WORK

made fast in two separate strips, no danger could be expected unless
the influence of the angle between the legs of the strips were taken
into account, this angle being 160° in this case.
For a sling with 2 legs the formula
T=

W

2 cos <p
is applicable.
T = actual tension in each leg;
<p = angle with the vertical line through the point of support ;
W= weight of the load.
In this case T = •
— = about 735 kg.
2X0.17
It is thus evident that it was quite wrong to hoist these bales of
wool with hooks made fast in the strips, the stresses in the latter
being much higher than could be tolerated.
As on such bales the strips are usually fastened with great force
by means of mechanical devices, the angle between their legs
when.used for hoisting may even exceed 160°; and it is interesting
to note that in the case dealt with above an increase of only 10°
in the angle between their legs would nearly double the tension in
the strips.
A.somewhat similar condition arises when a single sling is taken
around a load and the hook, ring or egg link is in the bight of the
lifting chain. This method should therefore only be used when it is
absolutely necessary ; in such cases the strength of the sling should
be at least double that of the sling used for the same weight on a
straight lift and the bight should not be forced down nearer the
load than a distance of one quarter the length of either of the inclined legs.
The strength of a sling depends on factors that may operate
together or separately. For fibre ropes these factors include:
(a)
ib)
(c)
{d)
(e)
{/)

the circumference of the rope;
the quality of the material used;
the lay of the rope;
••
• -...
splices and knots;
the number of strands; and
the cross section of the hook (or shackle bolt) where the
sling is suspended.

For steel wire ropes the influence of (a), (b) and (d) is, of course,
very important, (c) and (e) exercising comparatively little influence,

29

STRENGTH Ol? SLINGS

while the influence of (J) is not as important for steel wire rope as
for fibre rope.
The flexibility of the rope, however, is an important factor, while
for chain slings the diameter and quality of the material and the
form of the links are important. The flexibility of a wire rope is
determined by the number of wires per strand. Flexible rope for
shipping purposes is usually 6 X 12 and special flexible 6 X 24.
As a very large proportion of the slings used are made of manilla
rope1, the very variable factor introduced by the cross section of the
hook will be dealt with first. It is obvious that a hook with a sharp
edge (a small diameter) acts more or less as a knife and tends t o
cut the rope in two and accordingly a broad contact surface is to
be recommended.
Further, a double sling, used with both parts vertical, is not
double the strength of two single parts of the same material, as
will be proved below.
A distinct difference exists between the stresses in the two following cases:
(1) A double sling taken round
the load, with one end taken
through the other and fixed in
the hook (fig. 22) ; and
(2) A sling with the load in the
middle, both ends being fixed in
the hook (figs. 23 and 24).

&
\

Method 1 is usual for cargo of
small and moderate weight; the
sling is made of manilla rope or
sometimes of steel wire, both of
which slip sufficiently to fasten
the load in the sling. With this method it is very important that
the rope passing over the hook be kept as straight as possible. If
the loads are composed of corrosive goods liable to destroy fibre,
chain slings are sometimes used, but then method 2a (fig. 23) or
2b (fig. 24) is followed.
Methods 2a and lb are further applied with heavy loads, for
which manilla ropes are usually not strong enough, so that steel
1
During the war manilla rope has been almost entirely replaced by sisal
rope. The British Standards Institution has issued a specification for "Sisal
Ropes for General Purposes" (B.S.S. No. 908-1940). In this a factor of safety
of not less than 6 is recommended for new sisal ropes, but factors of 7 or 8 should
be used under adverse conditions of service.

30

SAFETY IN DOCK WORK

wire ropes or sometimes chains are used. Chains are not suitable
for method 1, as they do not slip sufficiently.

Fig. 23

Fig. 24

It is evident that, when working with method 1, the stresses in
the material are other and heavier than with the second method.
Hence method 1 is commoner for loads hoisted with manilla slings.
Very many tests have been carried out in this connection at
Rotterdam. The following table gives the results of 27 tests with
a single rope and 27 with a double sling each of the same coil of
manilla rope, the coils being, of various qualities and circumferences
and the legs being taken as parallel. The ropes were stretched
between two bolts of a testing machine ; the influence of differences
in the diameter of the bolts was eliminated by seeing that in all
tests one bolt had a diameter of 38 mm, the other being thicker.
Table VI, which could be completed from other tests, reveals
important differences in the results of the tests.
In No. 5, for instance, the strength of the single rope is almost

the same as that of the double sling, and in No. 20 the double sling
is 1.65 times as strong as the single rope.
When loading and unloading, the circumstances discussed above—
and others as well—have to be considered. The inference seems
justified that 1.235 or roughly 134 is the factor by which the breaking stress of the single manilla rope has to be multiplied to give the
safe working load of the double sling.
For double steel wire slings the results of the tests led to the
same conclusion. For double chain slings, which, however, are seldom used, the position is somewhat different. The weak point of
these appliances is to be found in the unfavourable combination of
stresses to which some links may be exposed. For the sake of uniformity it seems desirable to fix the strength of double slings with
parallel legs for all kinds of material at 134 times the strength of
the single rope or chain.
It is the safety factor that must ensure safety if the strength of
the double sling is less than 134 times that of the single fall.

CHAPTER V
MASTS AND DERRICKS
§ 1.—Masts
Although many accidents happen by crushing or breaking of
masts, inspection of these parts of the loading and unloading gear
is often neglected.
As a rule a mast stays in the vessel till the latter is broken up.
During the periodical surveys the masts are more or less superficially
examined but it cannot be denied that a really reliable examination
can only be made with the mast taken out.
The photographs in figs. 25 and 26, taken in 1937, show a mast
that was in use for loading and unloading only a few days previously.
Accidents with masts on new ships seldom occur. The following
table, relating t o the cracked masts which came to the knowledge
of the Netherlands Port Inspectorate in 1932-1936, seems to indicate that these accidents begin when the mast has reached a certain
age. The ships belonged to 10 nationalities.

In view of the fact that these statistics relate to a few ports
only, the number of masts cracked during the same period all over
the world must have been very considerable.

33

MASTS AND DERRICKS

It is remarkable that no accident of any kind has been recorded
with a mast less than 10 years old. The safety factor of masts
thus seems to be sufficient for the first vears of their life.

The wear and tear of this important part of ships' gear justifies
the contention that close attention must be paid to it during the
periodical surveys. For this purpose the masts should be lifted

34

out—the first time not later than during the third survey—so as to
allow of thorough investigation.
Under Lloyd's rules these surveys are required to be made at
intervals of 4 years. Special survey No. 1 specifies that masts,
spars, rigging anchors and general equipment of steam and sailing
ships are to be examined and either found or placed in good and
efficient condition.
§ 2.—Derricks
As these parts of the gear can be inspected more easily, the
situation is different from that with masts.
It has been observed that a considerable number of derricks
have fallen, but buckling or breaking of steel derricks, due to lack
of strength of the derrick itself, is rare. The cause is mostly to be
found in defective equipment or in faulty handling. This is proved
by the fact that on sea-going vessels of various nationalities, of 145
cases of collapsing derricks in the period January 1925-January
1937, 112 were due to defective equipment and 33 to faulty handling.
Thirty-two persons were injured, 7 fatally.
The steel derricks involved in these cases did not break, and the
causes of collapse were all found in spans, shackles, blocks, etc.,
or in faulty handling.
In the same period, however, 13 wooden derricks broke to pieces,
and in all these cases the wood appeared to be in a bad state or the
derricks had been used for a heavier load than the safe working load.
Consequently, it will be useful to touch on the strength of wooden
derricks. It is true that all new sea-going ships are fitted out with
steel derricks, but older ships have to be judged too, while in the
coasting trade and inland navigation wood is still often used, for
derricks. As a matter of fact the strength of wooden derricks is
often misjudged.
In 1906, Niels OLSEN published a diagram showing the strength
of wooden derricks 1 and the diagram reproduced here is based on
this (fig. 27).
In this diagram:
I = moment of inertia;
E = modulus of elasticity;
L = length of derrick in m;
D = greatest diameter of derrick in mm;
R = axial load on derrick in kg;
For European pitch-pine E = 95,000;
For American pitch-pine E = 145,000.

SAFETY IN DOCK WORK

The diagram is constructed for European pitch-pine and the
diameter of American pitch-pine derricks is about 0.9 times the
corresponding European diameter.
Example:
If the diameter of an American pitch-pine derrick with a length
of 12 m is wanted, for a safe working load of 3 tons,
length mast
h
0
— = — = (J.o,
length derrick
/
the axial load on the derrick (i?) for a load of 1 ton is found in
the curve in the lower right-hand corner of the diagram as 2.3
tons. The safe working load being 3 tons, however, R becomes 3
times 2.3 tons '= 6.9.
For a derrick length = 12 m and R = 6.9 tons the diagram gives
a derrick diameter of 360 ram for European pitch-pine, or 0.9
times 360 = 324 mm for American pitch-pine.
Wooden derricks for a safe working load over 3 tons should not
be used.
It may be added that the rules of the Germanischer Lloyd, 1929,
page 50, require a safety factor of about 8, and at least 6, and
calculate this factor with the formula
5£>4
safety factor =
PbL*
in which :
D = diameter of derrick in cm, measured in the middle;
Pb = axial load in kg;
L = length of derrick in m, measured from centre of gooseneck to middle of neckband.

C H A P T E R VI
DERRICK SPANS
As regards stresses in the derrick spans the reader is referred to
Chapter II; in the present chapter only the span arrangements will
be dealt with.
The safest method is represented in fig. 28. After the derrick
has been moved to the angle desired with the aid of tackle a and
the winch, the manilla runner of this tackle is fixed to a bollard
on deck. The upper block of the tackle is fixed to a triangle plate
and the lower block to an iron strip on deck, the second hole in this

Fig. 28

strip being destined for the span chain b, the upper end of which is
fixed with a shackle to the triangular plate or a similar construction
for the same purpose, e.g. a socket in which the span wire has been
sealed and a hole made for fastening the span chain. During loading and unloading the derrick is carried by chain and steel wire

38

SAFETY IN DOCK WORK

rope and the tackle may be used as a preventer. Raising or lowering
of the derrick can be done very easily and without danger for the
workers, and it is almost impossible for the runner to slip out of
their hands.
Another method is shown in fig. 29 where a special wire rope c,
running through a snatch block, replaces the manilla tackle with
the manilla runner. If this topping lift is adequately fixed on a
barrel or drum with a shackle or hook, this method also may be
considered safe.

Fig. 29

In fig. 30 the steel wire rope topping lift is taken directly around
the barrel or drum. This method is not to be considered as safe as
that shown in fig. 29. When the lift is fixed on the barrel or drum,
however, and the wire rope is of good flexible quality, it may be
considered safe, provided that the span wire is kept taut round the
cleat during hoisting or lowering so that the derrick cannot fall
down.if the man handling the lift lets it slip because it is too slippery
through oil, or his hands are too cold, or because he is struck by a
broken wire.
It is evident, however, that there is an element of danger with
this type which should not be neglected ; in fact it has caused several
serious accidents.

DERRICK SPANS

39

The dangers inherent in the arrangement in fig. 30 are also
inherent in the arrangement in fig. 31, and to an even greater extent,
because:

Fig. 31

40

SAFBTY IN DOCK WORK

(1) The span wire rope is as a rule less flexible;
(2) The wire rope is always under strain when the derrick is
used so that broken wires may more readily be expected, the more
so as a span wire rope of such dimensions is rather expensive, and
therefore is kept in use for a great many years ;
(3) The entire weight of the derrick hangs on the wire rope
when the men have to transfer the wire from the cleats to the
winch. It has often happened that for different reasons they could
not keep it tight, with the result that the derrick fell down;
(4) The stopper is often unreliable, especially when the wire
rope or the stopper is oily. "
By using a really reliable stopper the danger might be overcome. Several types have been invented, but as far as is known
they are not reliable after some years of use.
In fig. 32 an arrangement is shown which is often applied as
being much safer than that in fig. 31 since the steel wire rope may
be more flexible. The tackle enables the men to transfer the span
wire rope from the cleats to the winch and vice versa, and raise or
lower the derrick without exerting too much force.

Fig. 32

In consequence there is less danger of the wire rope slipping
out of their hands, especially when a good stopper is used.
Nevertheless, several serious accidents have happened with this
arrangement, principally because the wire rope came off the cleats

DERRICK SPANS

41

when the derricks were lowered by veering out the span wire rope
on these cleats instead of on an efficient bollard, but also during
the transfer of the wire rope to or from the winch.
It may be remarked here that the longer the arms of the cleats,
the smaller the danger of the wire rope coming off them.
Finally, an unusual method is shown in fig. 33 (two blocks
fixed to another). The method is safe if the topping lift is adequately fixed on the barrel or drum.

Fig. 33

The parts of the span wire ropes most exposed to wear and tear
are:
(a) The place where the span rests on the sheave of the span
block during loading and unloading;
(b) The place where the span rests on this sheave during the
voyage, especially when there is exposure to smoke and
gases from the funnel, that is if the spans are not stowed
away during the voyage.
In both cases the wire rope remains bent for a long time and
the strands are more or less twisted open at the same place, giving
admission to water and smoke and thus causing the inside of the
rope to become corroded.
Many span wire ropes have broken, sometimes causing bad
accidents to the dockers working in the vicinity.

42

SAFETY IN DOCK WORK

For this reason the periodical inspection must be carried out
•with the greatest care, and span wire ropes should be renewed as
soon as the slightest defect is observed. It is even advisable to
renew the spans on the occasion of every four-year survey or at
least every second survey if they are not condemned before.
It is worth mentioning that in 1937 the owners of a ship on
which a casualty had occurred owing to a span having broken declared before the Court that they intended to change the spans in
future at least every six years.
In the standing rigging the splice generally forms the weakest
place and it is necessary to remove the covering at every four-year
survey.

CHAPTER VII
BLOCKS
In stevedoring, blocks facilitate the hoisting, lowering and
trailing of goods and are also employed for moving the derricks.
They enable a comparatively small power to act as a much greater
power. Consequently they are greatly used in stevedoring and as
much ignorance exists concerning them, they will be considered
separately.
The number of sheaves determines the mechanical advantage
obtained in hoisting a certain load, as is shown in figs. 34 to 39.
Many practical men know that when hoisting a weight of p
tons with a rope led over one sheave it is necessary to exert a
pull of p tons at the other end, but they do not know that the
stress in the block and the fastening point amounts to 2p tons (see
fig. 34).
It is very useful to demonstrate this, and it can be done in a very
simple way by means of a spring balance as is shown in figs. 40-40c.
Men also know that when using double purchase (see fig. 35)
P
they only need a power of ~r~ tons to hoist a weight of p tons.
They are, however, often unconscious of the fact that the stress i a
3P
the block and the fastening point then amounts to ~~z" tons..
Figs. 36 to 39 inclusive speak for themselves.
Officers and petty officers on board and inspectors and foremen
of the stevedoring company, as well as seamen and dockers, should
be aware of these facts, because several severe accidents have been
due to the misuse of blocks.
When a load is hoisted, friction has to-be overcome and this is
generally estimated at 5 per cent, of the load per sheave. Whenthe safety factor is taken into account the increase in the stress is:
not very large if one sheave is used. If more sheaves are used this.
increase becomes larger and larger; in fig. 39 for instance, the increase is no less than 30 per cent.
Moreover, it is evident that greasing the blocks is a very i m portant matter that should not be neglected, otherwise the stresses.
may further increase.

The stresses have been calculated in the preceding pages with the
different parts of the runner in a vertical or nearly vertical position,
or with both parts parallel and thus having the same effect.
When these parts form angles, the stresses will change more or
less, as has been demonstrated in Chapter V, but it is always reasonable and safe to calculate the stresses in cargo blocks for a vertical
position of the different parts of the runner, because:
(a) the derrick is sometimes used in an almost vertical position,
in which case both parts of the runner are almost vertical
also (fig. 41) ;
(&) the place where the load has to be hooked on is not determined (trailing from under deck, etc.) and the different
parts of the runner may be almost parallel (fig. 42).

Fig. 41

For leading and span blocks there would be more reason to take
account of the angle, but these blocks are often interchangeable with
the cargo blocks ; and even if these three types of blocks have a somewhat different form- it is often possible to put one in the place of
another. From a practical point of view, owners often prefer the
same sizes for span, cargo and leading blocks, which seems the
safest.
The principles to be followed when using snatch blocks, blocks
for guys and the like are evident from the foregoing.
It will now be useful to describe briefly the conditions that a
block has to satisfy.
(1) All parts should be constructed according to the working
stresses that they may have to support, assuming a safety factor
of at least 5 for ordinary gear with which:

48

SAFETY IN DOCK WORK

(a) the diameter of the swivel must be suited to the anticipated tension ;
(b) the centre pin may be considered as a part mainly in shear.

Fig. 43

49

BLOCKS

(2) The runner must be prevented from coming between the
sheave and the housing.
(3) The lubricating system must work perfectly.
As it is sometimes the practice to use another material for the
swivel and pin than for the housing and sheave, specification of the
material is necessary.
Multiple-sheave blocks are often
designed with a shackle and bolt or
similar construction instead of a swivel. In this case the bolt may be
calculated in the same way as for the
centre pin. Figs. 43 and 44 may
explain this.

chapter only swivel blocks

' " ' :)e considered.
A standardised design for a singlesheave cargo block is reproduced in
figs. 45-48 in which the swivel and pin
are clearly shown.
A most important question is the
safe working load of a block.
As
always, the weakest part determines
the strength of the whole', and as the
centre pin is practically a part in
shear, the swivel, which is a part in
tension, forms the weakest part of the
construction, provided that the other
structural parts such as the shell
Fig. 44
and sheave have been calculated
correctly.
The diameter of the sheave, the size of which usually designates
the block, has nothing to do with the safe working load of the block,
as can be seen in the following table compiled by a world-renowned
manufacturer:
i flHUMaiV II C*

w

10 in. diameter single—tested to 10 tons on private machine
for 8 tons working load
12 in. diameter single—
idem
14 in. diameter single—
16 in. diameter single—
Swivel bolt and centre pin are generally of the same or almost
the same diameter, and the rupturing tensile stress may be calculated at half the breaking stress when shearing is taken into account.

50

S A F ß T Y I N DOCK WORK

Moreover, the swivel is generally forged, and hence the breaking
strength of the material cannot be much more than 34-42 kg/mm 2 ,
while the centre pin is sometimes made of material with a higher
breaking strength.
Considering what has been said above, the swivel bolt may as
a rule be taken as the weakest part of a block. Persons desirous of
ascertaining the approximate strength- of a block will do well to
measure the diameter of this bolt, and then the tensile strength
can be very easily calculated by multiplying the cross-sectional area
34-42
by — — kg/mm 2 , which may be taken for this purpose as the
breaking strength of material used for such bolts. If the specification of the material is known, the actual breaking strength has
naturally to be taken. If an inspector takes one fifth of the tensile
strength, he will have a sufficient idea of the strength of the block.
Moreover, it is quite clearly of the utmost importance to enter the
dimensions of the swivel bolt (if not the centre pin as well) on the
certificate.

Fig. 45

Figs. 46, 47 and 48

As to the marking of blocks much misunderstanding exists.
Practical users must know what load may be hoisted with a certain
block, and this should be indicated on the block.

51

BLOCKS

For single-sheave blocks used with a single runner this could be
done in a simple way by putting on the shell:
Load (to be hoisted)

tons.

With a double purchase, with one end of the runner fastened
to the upper or the lower block, and with multiple-sheave blocks
the question is not so simple.
The Netherlands Committee for Loading and Unloading Gear
etc. on Board Seagoing Ships advised in its Report of 1932 the marking of blocks as indicated in figs. 34 to 39. This method has the advantage of mentioning not merely the load that may be hoisted but
also the maximum allowable stresses in the principal parts of the
block. 1 Some manufacturers make a habit of marking their blocks
with the test load, but this should be discouraged.
The diameter of the sheave has to be determined in connection
with the wear of the wire. Most manufacturers designate their
blocks according to the diameter measured at the outer circum-.
ference of the sheave (e.g. 16 in. block). In practice, however,
the diameter of the sheave measured at the bottom of the groove
is of more importance, since the bending of the wire depends
on the inner diameter. (À 16 in. block measured by the first
method would become a 15 in. block by the second method.) To
avoid misunderstanding, uniformity should be established.
Several countries have rules concerning the relationship between
sheave and wire and between wire and groove.
GERMANY: Vorschriften der See-Berufsgenossenschaft,
1935, page 34 (Sonderabdruck) :

No. 13,

The sheaves must have a diameter of about 15 times the diameter of the
wire.
GREAT B R I T A I N : British Standard Specification for Ships' Cargo
Lifting Blocks, No. 408, 1931 :

In some countries, e.g. Great Britain, the competent authorities do not

CHAPTER VIII
CHAINS, RINGS, HOOKS, SHACKLES, SWIVELS, ETC.
This subject has been elaborately dealt with in the Memorandum on Chains and Other Lifting Appliances by G. Stevenson
Taylor, already mentioned, in the publications of several standardisation committees and elsewhere; on the whole, it seems sufficient
to refer to these publications and to Article 9 of the Convention
(No. 32) concerning the protection against accidents of workers
employed in loading or unloading ships (revised 1932).l
It may be useful, however, to reproduce here the conclusions
reached a t the Reciprocity Conference, held in London, July 1935,
as regards testing and annealing with a view to amending and
completing regulations under the Dockers Convention. They read
as follows:
In substance the Conference recommended t h a t chains, shackles, rings, hooks
and swivels should be tested with a proof load 100 per cent, in excess of the safe
working load, b u t pitched chains, used with hand-operated pulley blocks and
shackles, rings, hooks or swivels permanently attached thereto should be tested
with a proof load SO per cent, in excess.
Every chain, shackle, ring, hook or swivel after it has been lengthened, altered
or repaired by welding should be tested and examined.
T h e r e c o m m e n d a t i o n s t h e n c o n t i n u e a s follows:
Chains, shackles, rings, hooks and swivels made of wrought (i.e. puddled)
iron should as a general rule be annealed.
T h e following classes of special gear may be exempted:
(1)
(2)
(3)
(4)

Chains m a d e of malleable cast iron;
Plate-link chains;
Pitched chains;
Rings, hooks, shackles and swivels permanently attached to pitched
chains, pulley blocks or weighing machines;
(5) Hooks a n d swivels having screw-threaded parts or ball bearings or other
case-hardened parts;
(6) " B o r d e a u x " connections.

In the present state of knowledge steel gear may also be exempted.
In all cases annealing should be carried out in a suitably constructed closed
furnace and n o t in an open fire.
1

See below, pp. 116-118.

CHAINS, RINGS, HOOKS, ETC.

55

For wrought iron gear the temperature should be between 600 and 700 C
and the exposure should last for between 30 and 60 minutes. Should new steel
gear be annealed the temperature should be t h a t generally employed for normalising, i.e. not less than 900°C.
*
After being annealed the article should be allowed to cool slowly and should
be carefully inspected.

The Conference evidently was not in a position to give a definite
opinion on annealing steel gear, and left the matter t o be dealt
with in national regulations. In fact, several countries have regulated
the annealing of steel gear with good results.
It now remains to deal with shackles. Careful attention should
be given to the bolts of shackles used at places where it is not
possible to keep them constantly under notice, and further they
should be securely fastened. For cargo and span block shackles,
for instance, fig. 52 shows a« adequate fastening.

Fig. 52

This type of shackle, however, is not practical for fastening the
runner hook, as it is too easy for the nut to catch under the coamings or elsewhere, and so cause an accident. Such shackles should
be of a type without protruding parts as shown in fig. 53. With
this type the bolt is screwed into the shackle, the rounded head of
the bolt being provided, for this purpose, with a square recess
into which a key can be inserted.
Mention must be made of a type of shackle, which is still to be
found on several merchant ships, and in which the fastening of the

56

SAFETY IN DOCK WORK

bolt is inadequate for rigging purposes, as has been proved by at
least one fatal accident. The bolt of this shackle had been fastened
by a cotter pin only, which had come out during the work; the
shackle bent open and consequently the derrick fell down, hitting
a dock worker, who died a few minutes afterwards.
The construction was as indicated in fig. 54. Shackles of this
type should never be used.

Fig. 53

Fig. 54

The standardisation committees in several countries have
done splendid work in designing good chains, shackles, hooks, etc.,
and the attention of all concerned is drawn to their publications.
The permissible wear of chains, etc., is also a matter for consideration. In some countries regulations on this subject have
been issued.
The Germanischer Lloyd for instance laid down in 1929 that
chains, etc., should be renewed when the section at certain places
has so diminished that it must be considered dangerous to use them.
As a rule they should be renewed if the wear at certain places has
reached 10 per cent, of the original diameter.

CHAINS, RINGS, HOOKS, ETC.

57

The German See-Berufsgenossenschaft laid down in 1935 that
parts (of the gear) that are worn down should be renewed when
the wear has reached 10 per cent, of the original diameter or of the
original dimensions.
In the Netherlands, the Report of the Committee for Loading
and Unloading Gear on Board Sea-going Ships expresses the opinion that chains, shackles, hooks, rings, swivels, rigging screws,
fastenings on deck, eyes, bolts and other forged material should
be renewed when one of the dimensions has diminished by more
than 15 per cent.
G. Stevenson Taylor states in his Memorandum that some
firms in his country have adopted standards of permissible wear,
e.g. a reduction in diameter of the iron of -^ inch for' chains up
to 1 inch, and Xs inch for chains over 1 inch, but the general
condition of the chain should also be taken into account.
Wear up to 15 per cent, of the diameter of the iron is allowed
in another standard, and even 25 per cent, wear may be permitted,

Fig. 55

58

- Fig. 57

when safe working loads are fixed so as to correspond with the
reduced sizes.
It is not sufficient, however, to have regulations about the permissible wear; every link, shackle, hook, etc., should be submitted
to frequent inspections and examinations. A great advantage of
periodical annealing is that it offers an opportunity for careful
examination of the chain, etc., since after all grease and dirt has
been removed by fire, the bare metal is exposed.1

Appliances, 1930, pp. 36-37.

It is regrettable that on many ships more frequent inspections
and examinations of cargo lifting gear are not carried out by the
responsible ships' officers, particularly when such gear has been
subject to severe usage or employed on cargoes such as sand, ore,
etc., which have a marked abrasive effect. Figs. 55, 56 and 57
show examples of grossly excessive wear of gear which came to
notice on sea-going ships in the port of Rotterdam; fig. 55 represents a bow shackle, fig. 56 a span swivel, and fig. 57 the bolt of a

CHAPTER IX

,

THE INFLUENCE OF QUALITY, LAY, SPLICES AND
NUMBER OF STRANDS ON THE STRENGTH OF
MANILLA AND STEEL WIRE ROPES
§1.—General Remarks
An enormous quantity of fibre and steel wire rope is used in
dock work, both for standing and running rigging and for loading
and unloading appliances, and above all for slings.
Stresses in material have been touched upon in Chapter II and
the strength of slings in Chapter IV.
Further consideration of manilla and steel wire ropes may find
a place here, and what applies to these ropes applies more or less to
other kinds of rope. For more extensive study reference may be
made to the literature on the subject.
Nowadays in the shipping world fibre ropes are almost always
made of manilla, but occasionally sisal, hemp, flax, coco and other
fibres are used. During the present war, sisal has been extensively
used in place of manilla, which has become practically unobtainable.

§2.—Manilla Ropes
When judging manilla ropes the following points have to be
considered :
(a) material: outward appearance, weight per unit, length,
quality and breaking strength of the fibre and of the rope,
addition of oil and chemical composition of the oil used;
(b) nominal dimensions and method of measuring;
(c) method of measuring the breaking strength of the rope;
(d) breaking length.
(a)

Material

Ropes display great differences in quality, and it is of the utmost
importance t h a t the certificates should mention the breaking
strength, and here a clear distinction must be drawn between the
real and the calculated breaking strength. For practical purposes

MANILLA AND STEEL WIRE ROPES

61

it is necessary to know the former, which is as a rule the lower
of the two.
The weight of the rope'per unit length is in proportion to the
quantity of fibre utilised in its manufacture.
A soft laid manilla rope of some six strands may have a high breaking strength when used as a single fall, since the fibres, yarns and
strands are not much bent. The same rope may, however-, have a
low breaking strength when used as a sling, as the loose lay causes
the rope to be flattened on the bolt or hook of the testing machine.
If on the contrary a four-strand rope is hard laid the breaking
strength of the single fall may be lower, as the fibres, etc., are bent
more, and the breaking strength of the sling may be greater, as the
rope remains more or less round when stretched between the hooks
or shackles of the testing machine.
Of course on the whole, soft laid rope is weaker than rope with
relatively more fibre (hard laid), the difference varying with the
size and firmness of the yarns and strands and with the lay.
The addition of oil, which is made to preserve the rope and to
lubricate the fibres, may have a great influence on the weight,
and'this point should be considered carefully. No corrosive substance may be added, nor any substance for weighting purposes.
The quantity of lubricant used should form 8 to 12 per cent.
of the weight of the rope.
For good rope the fibre used in manufacture should consist
solely of new genuine long fibre manilla, when this is obtainable.
The fibre shall be well hackled and free from shorts. Though the
longest fibres are 3 to 4 m in length, fibre used in the manufacture
is seldom longer than 2 in. Indeed, shorter fibres and even very
short fibres are often used, a fact that influences the breaking
strength considerably. The strands of the rope shall be well formed
and shall be free from grooves and sunken yarns. As it is not always
possible to judge the rope from its appearance, a heavy responsibility rests on the shoulders of the dealers who sell inferior manilla
to customers who, considering price, outward appearance and
sometimes certificates, may think they have bought good rope and
use it as such. On the other hand, shipowners, captains and stevedores bear great responsibility, if out of misplaced thrift they
buy cheap rope and thus endanger the lives of their workers, who
have to use it without being aware of its inferior quality.
Sometimes the charter party requires the stevedore to use the
ship's manilla slings. This is to be deprecated as it is the stevedore
who has the responsibility. The interests of the two parties are
opposite in such cases, the captain wanting to keep his expenses
as low as possible, and the stevedore wanting to work as quickly

62

SAFETY IN DOCK WORK

as possible. T h e latter, then, must make his sling loads as large as
the circumstances permit.
If no certificates are available and there is no occasion to test
the ropes, the following table, based on a medium quality of manilia, may give some guidance.

(b) Nominal Dimensions and Method of Measuring
Manilla rope is generally designated according to the circumference; in some countries the diameter is given too.
The circumference should be measured when the rope is slack
and taken as the mean of a t least five separate measurements made
with a steel or paper strip, so that the strip follows a bent line
(fig. 58). It is not usual to take as the circumference a circle which

Fig. 58

Fig. 59

touches the outer edges of the rope (fig. 59). For a three-strand rope
the measurements obtained by these two methods would differ
by about 10 per cent.

MANILLA AND STBBL WIRB ROPßS

63

Instruments exist on which the circumference can be read
immediately, but not as accurately as with the strip.
The circumference of a used rope may differ very considerably
from that of the rope when new.
(c) Method of Measuring the Breaking Strength of the Rope
The best method is to stretch the rope between two holdfasts
(vices) of the testing machine, which enables the more or less incalculable influence of the splices to be left out of account. The
results will be different according as a long or a short length of
rope is gripped by the vice.
Factors influencing the strength of a rope, include the strength
of the yarns in combination with the length of the piece which is
tested, and the lay of the rope.
As the average length of the fibres may be estimated at 1,000
to 1,500 mm it seems reasonable to make the test piece the same
length.
(d) Breaking Length
A good idea of the strength of a rope is given by the "breaking
length", meaning the number of km of rope, the weight of which
is the same as the breaking strength.
The breaking length of ropes of the same material and of the
same lay is constant and independent of the diameter. Consequently it is very easy to compare the quality of ropes of different sizes
and qualities when the breaking length is known.
So far the breaking length has not often been used but the
advantages that it offers for the future justify some mention of it.
§3.—Steel and Iron Wire Ropes
In some countries the term "iron" has been dropped and only
the term "steel wire rope" is in use, but as in several important
countries "iron" still remains and many manufacturers make use
of it, iron wire may appropriately be discussed here.
By reason of their lower breaking strength so-called iron wire
ropes have to be thicker than steel wire ropes. Some shipowners,
especially of small ships, prefer them for their standing rigging,
because they look steadier than the comparatively thin steel wire
ropes of the same breaking strength. Moreover, they deem it an
advantage that the same degree of wear causes a smaller decrease
in the total breaking strength. These considerations make them
forget the advantages of steel wire.
As the safe load of the gear of new ships; both large and small,
is gradually increasing, iron wire ropes are becoming too clumsy

64

SAFETY IN DOCK WORK

and are steadily disappearing, but in. their turn, steel wire ropes,
especially for heavy gear, have found a serious competitor in steel
rods.
As a rule, material of a breaking strength of 130-180 kg/mm 2
is in use for steel wires, 130-140 kg/mm 2 being most common;
material of a lower breaking strength is generally called iron.
Iron wire is generally made of material with a breaking strength
of 40-45 and 60-70 kg/mm 2 .
The ropes should be of a composition suited to the operations
for which they are intended.
For the standing rigging, steel wire ropes of 7 strands with 7,
12 or 19 wires to the strand are recommended, the choice of the
number of wires depending on the circumference of the rope, and
the diameter of the wires, as it bears on the suitability of the rope
for splicing.
For runners, the ropes should be more flexible and the 6 X 1 2
quality with 7 hemp cores is considered more suitable when the
circumference is 51 mm (2 in.) or less, and the 6 X 24 quality with
7 hemp cores for greater circumferences.
For spans and guy pennants with a circumference of 51 mm
(2 in.) or less, the 6 X 12 construction with 7 hemp cores or the
6 X 1 9 with one hemp core is recommended, and for a greater circumference, the 6 X 24 construction with 7 hemp cores, or the 6 X 1 9
with 1 hemp core.
The choice of the strength and composition of the rope depends
on the anticipated strain in conjunction with the safety factor, the
diameter of the drum or sheave for which the rope is intended, and
any special circumstances in the operations. The completed rope
shall be securely and evenly laid.
Ropes should be adequately greased at regular intervals, care
being taken t h a t the grease is entirely free from acid.
All wires have to be galvanised, which lengthens the life of the
rope considerably but decreases the strength by about 10 per cent.
In some countries; however, galvanising is only advised for standing rigging.
As to the tensile test (it should not be forgotten that the actual
breaking strength must be known, which is about 85-90 per cent.
of the calculated breaking strength), the wrapping test and other
tests which may be prescribed, attention is drawn to Government
regulations and to those issued by standards associations and
classification bureaux.
Even if the core of a steel wire rope is made of metal, it is not
always made of the same metal as the other strands. If it consists
of a strand of steel wires, it may increase the real breaking strength,

MANILLA AND STEEL WIRE ROPES

65

but it must not be forgotten that the twisting of this central strand
is different from that of the other strands, while splicing is difficult
and often neglected. If on the contrary the wires are melted in,
this factor is of no account.
At the same time it seems reasonable to assume that as long as
the core is not broken, it increases the strength of the rope.
Some countries have prescribed that in calculating the breaking
strength the core may only be partly taken into account.
The question of when a wire rope has become unfit for use has
been dealt with by various countries.
The British Docks Regulations, 1934, contain the following
regulation :
Section ZO—(c). No wire rope shall be used in hoisting or lowering if in any
length of eight diameters the total number of visible broken wires exceeds 10 per
cent, of the total number of wires, or the rope shows signs of excessive wear,
corrosion or other defect which, in the opinion of the person who inspects it,
renders it unfit for use.

In the Netherlands, iron and steel wire ropes have to be renewed
when extensive corrosion has occurred or when more than 10 per
cent, of the total number of wires have been broken over a length
of 10 times the diameter of the rope.

CHAPTER

X

TESTING AND EXAMINATION OF LIFTING MACHINES
AND GEAR BEFORE BEING TAKEN INTO USE
Article 9 of the Convention (No. 32) concerning the protection
against accidents of workers employed in loading or unloading
ships (revised 1932)1 provides for the issue of appropriate regulations to ensure t h a t no hoisting machine, or gear, whether fixed
or loose, used in connection therewith, is employed in stevedoring
operations ashore or on board ship unless it is in a safe working
condition.
This provision of the Convention has been supplemented by
the recommendations of the Reciprocity Conference, London,
1935, as follows:(1) T e s t s and e x a m i n a t i o n s of h o i s t i n g m a c h i n e s and gear o n board.
Before being taken into use:
(a) Every winch with the whole of the gear accessory thereto (including
derricks, goose-necks, eye-plates, eye-bolts or oilier attachments) should be
tested with a proof load which should exceed the safe working load as follows:
Safe working load
Up to 20 tons
20 — 50 tons
Over 50 tons

Proof load25 per cent, in excess
5 tons in excess
10 per cent, in excess

The proof load should be hoisted with the ship's normal tackle with the derrick a t an angle which should not be more than 15 to the horizontal, or when
this is impracticable, at the lowest practicable angle. The angle a t which the test
was made should be stated in the certificate of the test. After the proof load
has been hoisted, it should then be swung as far as possible in both directions.
As a general rule all tests should be carried out in this way by dead load, and
no exception should be allowed in the case of gear on new ships. In the case
of replacements or renewals, however, spring or hydraulic balances may be used
where dead loads a r e not available. Where a spring or hydraulic balance is
used it should be reliable and accurate and the test should not be regarded as
satisfactory unless t h e indicator remains constant for a period of at least several
minutes.
Thorough examination for the purposes of Article 9 (2) of the Convention
should be understood to mean a visual examination, supplemented if necessary
by other means such as a hammer test, carried out as carefully as the conditions
1

See below, p. 116.

TESTING AND EXAMINATION

67

permit in order to arrive a t a reliable conclusion as to the safety of the parts
examined; and if necessary for this purpose, parts of the machines or gear must
be dismantled.
(b) Every crane and other hoisting machine with its accessory gear should be
tested with a proof load, which should exceed the safe working load as follows:
Saje working load

Proof load

Up to 20 tons
20 — 50 tons
Over 50 tons

25 per cent, in excess
5 tons in excess
10 per cent, in excess

The said proof load should be hoisted and swung as far as possible in both
directions. If the jib of the crane has a variable radius, it should be tested with a
proof load as defined above a t the maximum and minimum radii of the jib. In
hydraulic cranes where, owing to the limitation of pressure, it is impossible to hoist
a load 25 per cent, in excess of the safe working load, it will be sufficient to hoist
the greatest possible load.
(c) Wire ropes should be tested by sample, a piece being tested to destruction.

Chains, shackles, rings, hooks, swivels and pulley blocks have
already been dealt with in this connection in Chapter VIII.
There is sometimes a difficulty in finding a dead load for the
purpose, but fig. 60, showing the testing of a 50-ton derrick with

Fig. 60

a proof load of 55 tons, suggests that with a little good will it is
always possible to find the necessary load.
The component parts of the test load must of course be adequately fastened, as is shown in fig. 61.

68

SAFBTY IN DOCK WORK

A test with the aid of a spring or hydraulic balance does not
allow the- test load to be swung as far as possible from port to
starboard. Moreover, stays, shrouds, guys, fastening points of span
and guy blocks, etc., or in short the gear as a whole, are not submitted to a test that can be relied upon when hoisting and lowering a load equal to the safe working load under working conditions..

Fig. 61

Owing to the risk of breakage of a part of the gear during the
test, the load should not be hoisted higher than is absolutely necessary and a preventer wire should be attached. Hatches must be
kept closed, so that if anything breaks the load will fall only a
short distance and will not damage the bottom of the ship.

CHAPTER X I
MEANS OF ACCESS TO HOLD, FROM SHORE TO SHIP,
FROM RAILING TO DECK, AND TO SHIPS NOT LYING
ALONGSIDE A QUAY OR ANOTHER SHIP
§ 1.—Means of Access to Hold
Inadequate means of access have been the cause of many accidents. An example of very dangerous ladders and cleats is seen
in fig. 62.

Fig. 62

Article 5 of the Convention (No. 32) concerning the protection
against accidents of workers employed in loading or unloading ships

70

SAFETY IN DOCK WORK

(revised 1932)l contains a fairly complete set of regulations on
ladders.
It should be borne in mind that most of the dimensions specified
in this article are minima, e.g. the width of the rungs of a ladder
must not be less than 10 inches (25 cm), but for new ships a width
of 30 cm is recommended and in fact accepted in several countries.
A very important point is the number of ladders available in
a hold. The increasing size of hatches raises the question whether
in hatches above a certain length two ladders should be installed,
one fore and one aft, and alongships or thwartships, according to
the conditions in the hold. Some countries have already issued
regulations on this point; in Germany the limit of 5 m is fixed,
subject to certain exceptions (See-Berufsgenossenschaft) ; and in
the Netherlands the limit is 10 m. If shifting boards are placed a
second ladder is always necessary, partly because ladders are often
rendered inaccessible by having goods stowed around them, especially in ships tarrying general cargo for many destinations. It
is advisable to build the ladders off the centre line, especially if
there is any likelihood of grain being carried, and hence shifting
boards being required.

Fig. 63

If separate small deck openings have been made or ventilators
are used for the entrance to the hold, as is often the case on ships
built for carrying ore and coal, the dimensions of these openings
1

See below, p. 114.

MEANS OF ACCESS

71

and any manholes should n o t . b e too small, because the ladder
should enable the workers to escape quickly from the hold in emergencies (explosion, fire, etc.). The minimum should be 60 X 60 cm,
or 60 cm inner diameter in the case of round openings.
Fig. 63 shows a good deck opening, giving access to the iron
hold ladders behind the deck stanchions (seen in fig. 64).

Fig. 64

The means of access to the ladder on deck has to be wide enough
to enable the workers to reach the ladder without endangering
their lives. It should be at least 40 cm wide; and if it leads along
moving parts, 50 cm is recommended.
' The increasing depth of the holds creates a very difficult problem; on big passenger ships the ladder in a trunk hatchway mav
be 30 or 40 m long. When the dockers in the hold have to escape
quickly (fire, explosion, poisonous gases), an old or asthmatic
man may not be able to reach the top of the ladder without taking
a rest, thus blocking the way for his mates. Moreover, this long

72

SAFETY IN DOCK WORK

unprotected ladder may be dangerous for men who are not accustomed to it and are liable to giddiness. For these reasons such
ladders should be interrupted at certain distances (e.g. at every
10 or 15 m), but a system of sloping ladders near the hatchway is
preferable.
Shipbuilders have been aiming at ladders that facilitate access
to the hold; fig. 65 shows ladders sloping from deck to deck on a
cargo ship.

Fig. 65

MEANS OF ACCESS

73

Fig. 66 shows a means of protecting a vertical hold ladder.
Every precaution should be taken to facilitate the escape of
the workers employed in the hold. Means to this end include escape
hatches and semicircular tubes with rungs, hung at the top of

Fig. 66

the coamings. These tubes also possess the advantage of allowing
supervisors to enter and leave the hold easily.
Figs. 67 and 68 illustrate this.

§2.—Means of Access from Shore to Ship and from
Railing to Deck
Article 3 of the Convention (No. 32) concerning the protection
against accidents of workers employed in loading or unloading,
ships (revised 1932)1 contains several provisions on this subject.

See below, p. 113.

75

The permissible slope of the gangways depends on several circumstances.
A steep gangway may be
climbed without any danger
if it is provided with stepping
laths of a practical form and
of adequate dimensions, as
shown in fig. 69.
The same gangway without or with inadequate laths
would be unsafe at the angle
shown.
A dangerous spot some/
"" times exists where the ganging. 69
way reaches the ship's railing, and the steeper the
gangway the greater the danger.
Sometimes a person boarding the ship has practically no handhold when he leaves the gangway for the stepladder leading from
railing to deck, unless a stanchion is placed on the railing or on the
stepladder, or other means are provided to protect this spot, which
is all the more dangerous when there is a gap between the end of
the gangway and the top of the railing.
Fig. 70 illustrates access by means of a stepladder with stanchion, but as the ship's accommodation ladder is used here, the
danger is not so obvious as with a gangway.

Fig. 70

76

SAFETY IN DOCK WORK

A practical improvement, shown in figs. 71-72, is often used on
smaller German ships. The last stanchion is of a special form and
movable, and thus always provides a firm handhold.

Fig. 71

Fig. 7.2

A similar though less serious danger exists when the quay is
higher than the top of the railing; the German system obviates this
danger also.

MEAN'S OF ACCESS

77

Further, appropriate measures should be taken to prevent the
foot of a stanchion from being accidentally lifted out.
Special attention should be given to rope ladders. With round
rungs they should not be used for stevedoring work. Steps should
be of sufficient width to provide a good foothold, and the ladder
should be so constructed that the steps remain horizontal.
•If in an exceptional case a rope ladder has temporarily to be
used for entering a hold, it should be fixed at the bottom also to
prevent it from swinging or turning round. Rope ladders used on
the outside of a ship should have one or more horizontal laths fixed
at the back to prevent them from turning round.
§ 3.—Means of Access to Ships not Lying Alongside a Quay
Article 4 of the Convention (No. 32) concerning the protection
against accidents of workers employed in loading or unloading
ships (revised 1932)1 has something to say on this subject, which
is a very important one, for the lives of many dockers are endangered
by failure to take appropriate measures to ensure their safe transport.
Vessels loaded or perhaps overloaded with dockers going to or
coming from their work may be exposed to serious danger, owing
to conditions of navigation, especially in stormy weather when a
strong current is running, or visibility is decreased by fog, snow or
rain. Other sources of accident are vessels in a bad state or insufficiently manned.
In a few countries regulations have been issued concerning the
conveyance of dockers by ship. As far as is known the regulations
in force at Rotterdam are the most detailed and an extract from
them is given below:
Section 3

CHAPTER XII
HATCHES, HATCHWAYS, HATCH COVERINGS,
COAMINGS AND BEAMS
§ 1.—General Remarks
The purpose of hatchways and their equipment is not at all
the same on sea-going as on inland-waterway vessels.
On sea-going vessels they are subject to the requirements regarding the seaworthiness of ships, whereas on inland-waterway vessels
their principal purpose is the protection of the cargo. In some
cases, however, when inland-waterway vessels have to sail on broad
rivers or lakes, seaworthiness is an important matter. In this
chapter only sea-going ships are considered.

Fig. 73

§ 2.—Hatches
The dimensions of hatches have steadily increased. This does
not endanger the lives of the workers, unless the remaining deck
space is insufficient for safety. In this connection it should be

80

SAFETY IN DOCK WORK

remembered that hatch coverings and beams when lifted out are
often put on deck. They should preferably be stowed as near as
possible to the sides. Sufficient space should be left around the
coamings for workers to pass, and for signal men, tally men, supervisors and other people concerned with the cargo to stand safely
near the hatch. The working space around the hatches of 'tweendecks should also be sufficient to enable the workers to remove and
replace beams and hatch coverings in safety.
Fig. 73 illustrates an example that should not be followed:
the deck cargo had been stowed sufficiently far from the coamings,
but the stevedore has used the free space for the beams.
§ 3.—Hatchways
Larger hatches have meant larger hatchways. This is an advantage for the workers in that loads cannot so easily bump against
the coamings and by falling injure those in the hold.
If, however, there is practically no place left for the workers
to take shelter under the decks when loads are hoisted or lowered,
they may be in danger, the more so as the increased size of the
hatchways may induce the stevedoring company to put more
shifts in the hold than can be deemed safe, in order to hasten the
work.
Persons responsible for safety should keep a sharp watch on
these points.
§4.—Hatch Coverings
Up to a few years ago hatches were covered by means of wooden
coverings resting on fore and aft beams and thwartship beams.
When the hatches were small the beams were sometimes of wood,
but on modern ships only steel thwartship beams are to be found,
and fore and aft beams have disappeared. Consequently, wooden
hatch coverings are always placed alongships.
Moreover, since shipbuilders have been convinced of the advantage of making all hatch coverings of the same dimensions,
so that .they can be interchanged without the slightest danger to
the workers, the risk of being hit by badly fitting coverings has
diminished considerably, but the greatest care should be taken to
avoid these accidents on older ships. (If the construction does not
allow the last section of a hold to be covered in the same way as
the others, the difference should be so apparent that no mistake is
possible.)
Another advantage of making all hatch coverings interchangeable is that marking becomes unnecessary.

HATCHES, HATCHWAYS, ETC.

81

Fig. 74 illustrates the danger to the dockers when the hatches
have not been covered in a safe way. It is easy to see that a load
touching coverings that are too long or placed in an unsafe way
may displace them and cause serious accidents.

Fig. 74

Hatch coverings should be kept in good repair and should not
therefore be used in the construction of deck or cargo stages or for
any other purpose which may expose them to damage.
Special attention should be given to the parts of the coamings
and beams on which the ends of the hatch coverings rest.
According to the International Loadline Convention, London,
1930, these parts should be 63mm wide, and the German SeeBerufsgenossenschqft prescribes that they should be at least 75 mm
for hatch coverings lying alongships on vessels built after 1 January
1925.
Sometimes, to give the top of the beam an even surface, the
coverings touch each other and are kept in their place by wooden
cleats underneath. This is quite inadmissible. Inspection of these
cleats can only take place after part of the hatch has been opened
and an accident may occur while this is being done. Moreover,
this inspection will often be neglected.
The fatal and other severe accidents to a great many workers
through being hit by falling hatch coverings, together with the
loss of time incurred when opening or closing the larger hatches,
have led naval architects and many private inventors to seek an
adequate solution to the problem of safe hatch coverings.
Figs. 75 and 76 show systems that have been applied in practice.
However, the choice of a system of hatch coverings for a particular ship is not influenced merely by the time required to open

82

SAFETY IN DOCK WORK

»c.
K g . 75

Ftg. 76

HATCHES, HATCHWAYS, ETC.

'

83

and close the hatches and the safety of the operation, but also by
the possibility of damage to the cargo by leakage or by the temperature, which is likely to be higher under iron coverings than under
wooden ones.
Not only owners but also, and more especially, underwriters,
have an interest in the system adopted.

§ 5.—Coamings
Danger for the workers exists:
(1) When the coamings around the- hatch are not sufficiently
high; and
(2) When there are no coamings at all, this being the case on
several passenger ships or ships with passenger accommodation,
where a flush deck is wanted for purposes of recreation.
The Convention (No. 32) concerning the protection against
accidents of workers employed in loading or unloading ships (revised
1932)1 has the following regulations on this point:
Article 6 •
(1) While the workers are on a ship for the purpose of the processes, every
hatchway of a cargo hold accessible to the workers which exceeds 5 feet (1.50 m)
in depth from the level of the deck to the bottom of the hold, and which is not
protected to a clear height of 2 feet 6 inches (75 cm) b y the coamings, shall, when
not in use for the passage of goods, coal or other material, either be securely
fenced to a height of 3 feet (90 cm) or be securely covered. National laws or
regulations shall determine whether the requirements of this paragraph shall be
enforced during meal times and other short interruptions of work.
(2) Similar measures shall be taken when necessary to protect all other
openings in a deck which might be dangerous to the workers.

These regulations are found in the same or nearly the same
wording in several countries interested in the protection of dockers.
Besides the danger that this article provides against, there is
another inherent in the flush deck. Objects falling out of the hands
of a person standing near the coaming or from a scale may roll or
slide into the hatch and injure the workers in the hold. A fatal
accident has been caused by a barrel of paint rolling into the hold
on to a dockworker's head. The same danger may threaten persons
slipping on the deck when it is frozen, or slippery from oil, linseed
or water.
General agreement is lacking on this question, for in one country
the flush deck is absolutely forbidden, in other countries there are
1

See below, pp. 112 ff.

SAFETY IN DOCK WORK

84

no regulations on the point, and elsewhere the absence of a fixed
coaming is allowed, provided that loose but strong and adequately
fixed coamings are placed when the hatch is opened.
The following illustrations give an idea of a protecting system
that has proved satisfactory for several years (figs. 77 and 78).

85

§ 6.—Beams
It is evident that displacement of beams used for wooden hatch
coverings may cause the beam itself and also the coverings to fall
into the hold with disastrous results to the workers below. Hence
beams that are not removed should be adequately secured to prevent displacement.

Fig. 79

Fig. SO

86

SAFETY IN DOCK WORK

For this purpose the ends of the beam and the cleats in the
coamings are generally provided with corresponding holes, through
which a bolt is p u t . This bolt should be secured by a nut, as it has
happened several times that the bolt has worked loose with fatal
results.
I t is advisable to give an oval form to the hole so that the bolt
can be put in even when the coamings have moved a little, or
when dirt has prevented the beam from resting on the whole length
of the cleat.
The same serious accidents that led to the invention of new
types of hatch coverings prompted the invention of automatic
means of fastening the beams.
Some of these systems have proved efficient and the types shown
in figs. 79 and 80 are among them.
In the course of time these appliances pay for themselves, since
not only do fewer accidents happen, but also there are no bolts
and nuts, articles that very often disappear and have to be renewed.
No person should be allowed to go upon beams for the purpose
of adjusting the gear for removing and replacing them, because
experience has proved this to be very dangerous. The holes in the
beams required for lifting them should therefore be made sufficiently near the ends.

Fig. 81

On some ships removal of the beams is unnecessary, as is shown
in fig. 81.

CHAPTER XIII
LOADING AND UNLOADING OF GOODS TRANSPORTED
IN BULK AND OF GENERAL CARGO
§ 1.—Bulk Cargo
The safe handling of bulk cargo largely depends on the safety
of the machinery used. As this subject has been dealt with in
Chapter III and elsewhere, here it will only be necessary to supplement what has already been said.
When unloading with the aid of grabs, stevedoring undertakings, in order to save wages, often omit to post a signaller on deck.
When nobody is in the hold this may be exempt from danger, but
if trimmers are working in the hold a signaller is indispensable even
with large hatches. Moreover, a signaller is always necessary when
members of the crew and other persons have to pass over the deck.
When, too, goods are unloaded from lighters and loaded into a
sea-going ship, or vice versa, a signaller should be present, because
neither crew nor trimmers can see when the grab returns.
A second man should be placed on the shaft tunnel in order to
guide the grab and to give the necessary indications.
No grab should be hoisted, lowered or unloaded while anyone
enters or leaves, the hold along a ladder in the hatchway; for this
kind of work, access to the hold by means of small but adequate
separate hatches is advisable.
Grabs, even when empty, are heavy (an empty grab of a 30-ton
bridge crane weighs 20 tons).
Great care should be taken to avoid protruding parts on the
inside of grabs, since it frequently happens that small pieces of
coal or ore do not fall directly out of the opened grab but stay
behind a rivet head or nut and fall out as the grab swings back.

§2.—General Cargo
An immense variety of methods for handling general cargo is
applied all over the world in the loading and unloading of tens of
thousands of sea-going and hundreds of inland-waterway vessels.
These methods may be grouped in three main classes according
to the equipment used, namely:

88

SAFETY IN DOCK WORK

(a) machinery and gear belonging to the ship;
(b) shore and floating general cargo cranes;
(c) miscellaneous appliances for loading and unloading.
(a) Machinery and Gear Belonging to the Ship
A method t h a t is becoming more and more general is loading
and unloading with coupled derricks (with the aid of inner and outer
tackle).
The stresses in the runners may vary considerably, owing to
the weight of the load, the capacity of the winch and the angle
between the runners (depending on the length of the derricks in
connection with the height of the bulwarks and the dimensions of
the load). If the gear has not been specially constructed for this
method of working, the load should not be heavier than ¡Hs of the
safe working load of the slewing derrick and should never exceed
2 tons.
The stresses in the guys, moreover, may become very high,
according to the stresses in the runners and to the place on deck
or on the railing where the guys have been fastened.
When working with inner and outer tackle, preventers should
be placed on the guys, the top of which should be fastened at the
nock of the derrick and not at the guy pennant as is often done.
Further, this method of working should only be allowed with single
runners.
Many derricks have arrangements for working with double
purchase in order to lift heavy loads, and even three arrangements
are sometimes found, so that one derrick may have three different
safe working loads.
The stevedoring firm has to consider carefully which method
to apply for a certain load, and to make sure that all parts of the
gear that should be changed have actually been changed.
It is necessary to know the actual weight of the load and in
this connection reference must be made to thé Convention (No. 27)1
concerning marking of the weight on heavy packages transported by
vessels, adopted by the International Labour Conference in 1929.
If the dimensions of load, derrick and hatch do not allow the
load to be brought to its proper place in the hold by the derrick
only, one or more blocks and a manilla runner are sometimes used.
This method may also be applied when loading in lighters lying
alongside sea-going vessels, and for quay work.
The stresses in these blocks and runners are often underestimated
and the stevedores should take careful stock of the situation. 2

2

See below, p. 122.
For stresses in blocks, see Chapter V I I .

GOODS IN BULK AND GSNBRAL CARGO

89

Several accidents have occurred when dragging a load in the
hold to its place under deck with the aid of a winch ; the persons in
charge should keep a sharp watch on such operations.
The following sketch shows
the arrangement, seen from
above, found on board a ship
where a fatal accident had
occurred while the stevedore
tried to drag a load under deck
after it had been lowered into
the hold (fig. 82).
Tackle had been fastened
with a block B to the load, and
with another block A t o a n eye,
fixed to the ship. The runner
had been led through a snatch
block C to the 3-ton winch.
Owing to the weight of the load and to friction, the steam valve
had to be opened fully to move the load, so that the stress in the
runner amounted to at least 3 tons, and in block A and in the eye,
to about 9 tons. The eye proved to be the weakest place and
broke; the docker D was hit by block A and killed on the spot.
It may be generally stated that when a block is used, men
should never stand in the angle between the runners.
If the man who was fatally hit in the case quoted had not stood
in that angle but at a safer place, only material damage would have
been caused.
(b) Shore and Floating General Cargo Cranes
Much of what has been said under (a) applies also to loading and unloading with shore cranes. It may be worth while, however, to give an idea of the influence which a slight deviation of the
runner from the vertical may have on the movement of the load
itself when cranes with very long jibs are used, as is becoming more
and more frequent nowadays (see fig. 83).
A fatal accident occurred owing to the load bumping against
a part of the ship during discharge of a load measuring 1.6 X 2.2 m,
which would not have been too much if the load had risen vertically.
However, a deviation of the runner of one degree from the vertical
•caused the load to swing through 2 m in the horizontal plane during
the passage through the hatchway, and this nobody had foreseen.
This shows that the discharging of loads of such large dimensions
with all cranes should be allowed only through sufficiently large
hatchways and with guide ropes attached to the loads.

90

SAFETY IN DOCK WORK

Fig. 83

(c) Miscellaneous Appliances for Loading and Unloading
Appliances including trays, buckets, nets and other combinations of wood, iron, steel or manilla ropes, chains, etc., are used for
loading and unloading general cargo.
There are many types of tray—long, square, without sides,
with low sides, and with high sides. The modern type in use for
loading and unloading general cargo that is not slippery or in any
other way dangerous when being handled by trays, is almost square
and without sides and often constructed in such a way that when
loaded it may easily be transported from the quay to the shed, or
vice versa, by means of a combined electric truck and crane.

GOODS IN BUUC AND GENERAL CARGO

91

Trays without sides naturally increase the danger of parts of
the load falling off when bumping against the coamings or another
part of the ship ; but a tray properly loaded with small or large
wooden cases, or with other goods suitable for being hoisted in this
way, is not more dangerous without than with sides, if the load is
protected by the four-legged sling with which the tray is hoisted,
or otherwise. In fact, it is not the bottom but the top cases that
fall first when the tray touches a part of the ship, as has been proved
by a series of tests undertaken at Rotterdam.
Hence the precautions to be taken should consist in protecting
the whole load against displacement, and not primarily that part
of it which is directly placed on the tray, the friction against the
tray being often greater than between the parts of the load.
Fig. 84 illustrates the loading of long bags, effectively kept
together with the four legs of the sling.

Fig. 84 _

Slippery or round cargo or paving stones and patent fuel should
not be handled in this way, nor should such goods as glass or earthenware and; containers filled with corrosive substances.
Loads hoisted on these trays may be protected in different
ways, as shown in figs. 85 and 86, which speak for themselves.
When loading and unloading small, more or less square objects
such as coal briquettes, e t c , special measures should be taken.
If the goods are likely to be damaged, as is the case, for instance,
with soft building bricks, which are worthless when even a corner

92

GOODS IN BULK AND GBNERAL CARGO

93

is missing, they should be stacked on the tray in such a way that
the danger of falling off is reduced to a minimum. Fig. 87 gives an
example of such stacking.

Fig. ¿7

This method, however, cannot be recommended unreservedly
and some protection round the tray is sometimes necessary.
A very safe method of loading coal briquettes is shown in fig. 88.
The container has a movable bottom, carried by springs; the bottom
comes to the top when the container is empty, and descends as the
briquettes are put into it. Consequently, there is no risk at all of a
briquette falling out, even if a part of the ship is touched during
loading or unloading.
If such goods have an uneven surface, e.g. granite paving
bricks, it is too dangerous to stack them on a tray; they should be
handled in containers or the like. The utmost care should be taken
that these containers are loaded safely and that no goods can fall
out of them.

Round and slippery goods should be put in steel wire nets as is

In order not to damage the load it is sometimes necessary to
keep the legs of a sling spread as is shown in fig. 91.
Care should be taken, however, that enough pressure remains
on the component parts of the load or that other measures are taken ;
here, canvas has been used as protection to prevent anything from

When working with long iron, such as rails, etc., the following
method may be recommended. The ends of the iron are put in a
steel bucket, which is fastened to the load, as is shown in fig. 92
and there is no danger of a piece slipping out, while fig. 93 illustrates
the danger of hoisting the same load without a bucket.

CHAPTER XIV
INSPECTION AND SUPERVISION
§ 1.—Inspection
Article 17 of the Convention (No. 32) concerning protection
against accidents of workers employed in loading or unloading
ships (revised 1932)1 prescribes that provision shall be made for an
efficient system of inspection. 2
The establishment of an efficient port inspection service is of
extreme importance, not only for those countries that ratify the
Convention, but for all other maritime countries as well.
The port inspection service should preferably be organised under
the administration of the department responsible for the protection
of industrial workers throughout the country. Such an arrangement would have several advantages: labour inspection would.
form a complete whole within the framework of the department,
covering all branches of work in industry, commerce, transport,
etc.; the assistance of the medical, electrical, chemical and other
special auxiliary services attached to the department would be
directly available to all branches of the labour inspection force;
and these auxiliary services would then cover the entire field of
occupational accident prevention.
The inspection service should be responsible for the protection
of all workers employed on ships, in so far as their work is not
connected with the fitting out or navigation of the vessel. The
exact scope of its work must be determined by local conditions and
experience.
The inspection service should be autonomous, although under
the authority of the chief of the industrial inspection service. I t
should be entitled, on its own responsibility, to consult and call
on the services of shipping registration companies, technical associations, semi-official institutions, committees, etc.
In the larger ports the inspectorate should be under the orders
of an official with a sufficient technical and scientific training to
enable him to deal with any problem that may arise. He must

pp. 37-40.

98

SAFETY IN DOCK WORK

have a thorough knowledge of all the national and foreign laws and
treaties affecting his work and must himself be competent to draft
legislation and orders. He must be tactful in his dealings with
employers and workers, whether individually or through their
associations, and he must have a thorough knowledge of working
conditions in his own district and elsewhere.
He must be fully acquainted with the economic problems with
which the inspection service is increasingly being brought into
contact. He must be able to speak for the service on technical
subjects, labour questions, etc., at committee meetings and to represent his country at international conferences. He must be able
to maintain the necessary relations with foreign authorities and
other parties concerned.
In addition to his native language, he should have a sound
knowledge of the languages chiefly used in international dealings.
The chief inspector in a large seaport must have at his disposal
not only the necessary administrative staff but also a sufficient
number of inspectors to ensure efficiency.
Some of these inspectors must be capable of calculating, in so
far as this is possible without complicated mathematics, the strength
and stresses of hoisting gear and other appliances on land and on
board ship. They must be able to judge sketch plans—a very important matter in the case of new structures—and must have a
wide knowledge of materials. In short, their scientific training
must be sufficient to enable them to carry out all the duties entrusted to them and to submit detailed reports on their work, labour
conditions and any special subjects on which they are consulted.
Since it is essential for them to remain in close connection with
working conditions, they should exchange duties periodically with
the officials mentioned below.
The remaining inspectors must have sufficient technical knowledge to understand all the problems connected with the loading
and unloading of ships and must, like the others, be able to get on
with the workers and their foremen. They should be specially
responsible for supervising hours of work and must be able to
draft simple reports.
All the officials must know at least one of the chief languages
in addition to their own.
As cases frequently arise in connection with the loading and
unloading of ships (breaking of materials, dangerous methods of
work, excessive hours of work, etc.) in which immediate action and
decisions must be taken because of the short stay of the vessels
in port, the inspectors, or at least some of them, should have a
telephone at their disposal.

INSPECTION AND SUPERVISION

99

If many ships have to be inspected when moored away from
the quay, the inspectors should have one or more launches at their
disposal.
When small ports are situated near larger ones, the former
can be supervised by the inspection service of the latter. Otherwise,
or when this arrangement is considered undesirable, the inspection
duties in the small port, which will occupy only a very few hours
daily, may be carried out by an official of some other service who is
resident there and is acquainted with shipping matters. This can
be considered a subsidiary appointment for which some slight extra
remuneration may be paid! In this capacity the official will be
attached to the inspection service of a larger seaport.
§ 2.—Supervision
Dock work is fundamentally different from work in a factory
for the following reasons among others:
(a) The arrangements are different on almost every vessel and
as the ship often stays only a few hours in port, the dockers have
to work practically every day, and sometimes twice a day, with
different gear and under different circumstances.
(b) The ship may arrive at any hour of the day, and the work
has to begin as soon as possible to save time.
(c) In order to save time the stevedore has to hurry his work
as much as possible, and often too little time is given to matters
of safety. Quickness is wanted by the owners because the ship
represents a big capital item and has to be used for transport as
continuously as possible; the time spent in a port is often considered as lost time.
In view of all this, it is clear that the supervisors who are to be
responsible for the safety of the work must be carefully selected from
persons competent to direct loading and unloading. Moreover,
they should be capable of calculating stresses, judging difficult
situations and possibilities, and should realise that it is in the
interest of all concerned to avoid accidents, not only from a social
but also from an economic point of view.
It is a responsibility of the employers to choose the right supervisors and foremen. As there is a lack of such persons, owing to
the fact that hardly anywhere has anything been done to train
them for their difficult and complicated task, the creation of an
educational system for the persons from whom supervisors are
selected is a very urgent necessity.

CHAPTER XV
DISEASES, TOXIC AND OTHER HARMFUL SUBSTANCES
TO WHICH DOCK WORKERS ARE EXPOSED
§ 1.—General Remarks
Dock workers are exposed to several occupational diseases and
to toxic and other harmful substances and, though this is not the
place for a detailed discussion of them, the frequent injuries and
considerable loss of time for which they are responsible justify some
mention of them.
The dangers present during loading and unloading are different
from those during the voyage and may therefore be dealt with
separately.
§ 2.—Diseases
(a) Anthrax (from Hides, Wool, Hair, etc.)
Hides, wool and other products of animal origin are transported
from places all over the world to seaports and discharged from
the sea-going ships into lighters, sheds, wagons and trucks.
The danger to which transport workers are exposed by the very
resistant anthrax spores is obvious.
In an article on this subject in Reichsarbeitsblatt, 1932, No. 11,
Part III, Dr. A. B R A N D T concludes from the statistics of anthrax
infections at Hamburg in the years 1910-1914 and 1925-1931,
that it is the dockers and warehouse workers who are most exposed to this serious risk. The infection has rather frequently
(in about 25 per cent, of all cases) a fatal termination.

(b) Diseases of the Respiratory Organs, Generally Caused by Dust .
(from Various Kinds of Ore, Fertilisers, etc.)
Some cases are known of dock workers who have died of pneumonia after discharging certain kinds of ore. Ground basic slag
has caused numerous casualties in the course of some years. In
1936, for instance, nine dock workers who had discharged this
fertiliser from a sea-going ship died of pneumonia and several others
were ill.
(c) Inflammation of the Mucous Membranes of the Nose and Throat
(from Bone Dust, Dry Clay, Cement, Certain Ores, Fertilisers)
The throat may become dry and red and the workers are entirely
or partly prevented from breathing through the nose.
(d) Skin Burns, Eye Inflammation,
(from Pitch, etc.)

Conjunctivitis

Handling these substances is one of the most disagreeable jobs
that a docker has to perform, at least in certain circumstances.
With pitch of certain compositions severe conjunctivitis may
ensue and there may be rather painful inflammation of the skin.
(e) Skin Injuries, Skin Burns, Eye Burns (from Corrosives, etc.,
such as Soda Ash, Caustic Soda, Acetic Acid, some Fertilisers,
Whale Oil Residue)
The dangers of acid and alkaline substances are well known,
and the hands and necks of dock labourers are often exposed to
them. It is essential not to employ any person on this work who
is already suffering from skin injuries.
Sulphur dust may cause slight eye burns.
In some circumstances acrolein is formed in whale oil residue,
which may cause injuries to the mucous membranes, conjunctivitis,
etc.
§ 3.—Toxic Substances
(a) Phosphoretted Hydrogen (Impurities in Ferro-Silicon with a
Certain Percentage of Silicon)
Phosphoretted hydrogen may be given off by ferro-silicon and
similar substances containing a certain percentage of silicon, especially through the action of water. Although up to now the
health of dock workers has not suffered much from this risk it
should not be overlooked, for there is always a possibility that the
workers will go to sleep in the neighbourhood of such substances.
Slight inconveniences have in fact been experienced during loading

102

SAFETY IN DOCK WORK

and unloading. During sea and inland waterway transport, however,
very many serious accidents have occurred, and several seamen and
lightermen, together with members of their families and passengers,
have died through breathing phosphoretted hydrogen. Having
regard to the close connection between stevedoring and water
transport, it may be of interest to reproduce the most recent
regulations on this subject, those of the former Central Committee for Navigation on the Rhine (members: Belgium, France,
Germany, Great Britain, Italy, Netherlands, Switzerland) 1 :
Packing

and Transport

of Poisonous

Substances

The following poisonous" substances shall only be transported on the Rhine
subject to the following conditions:
I
II
Ill
IV. Ferro-silicon and mangano-silicon, with a silicon content of more than
30 and less than 90 per cent, and alloys of ferro-silicon containing admixtures of
other substances amounting in all to over 30 and less t h a n 90 per cent., including
silicon and excluding iron.
(1) The substances shall be packed in strong wooden or metal containers.
(2) The containers shall be provided with a clear and durable inscription
"Ferro-silicon", "Mangano-silicon" or "Alloy of Ferro-silicon", with the
addition "Poison, T o be kept dry. Do not overturn." The inscription
shall be affixed in the languages of the countries through which the ship
will pass. T h e inscription"may mention the silicon content. The addition of
a trade n a m e shall also be allowed.
(3) The substances shall not be transported by vessels carrying passengers.
(4) As far as possible, the substance and the packing shall be loaded and kept
in a d r y condition.
(5) The containers shall only be stowed in the following manner:
(o) on deck: protected against d a m p ;
(b) in the hold; in all holds if they are separated from the living accommodation by a gas-tight cofferdam; if there is no cofferdam, in the holds
not adjacent to the living accommodation provided t h a t these holds
are separated from the living accommodation by a tight metal bulkhead.
All holds and living accommodation shall be continuously ventilated
as well as possible.
(6) On board vessels transporting the substances mentioned under IV, there
shall be adequate means of ascertaining in a simple way whether phosphoretted hydrogen (PH3) has filtered into the living accommodation
and whether the cofferdams are sufficiently airtight.
Directions for using these means shall be kept on board.

DISEASES, HARMFUL SUBSTANCES

(b) Carbon Monoxide (CO) (Incomplete Combustion, e.g. inj the
Mess Rooms of Floating Cranes, when Unloading Fruit from
Stove-Heated Holds, etc.)
Some dockers who spent their break in the mess room of a
floating crane were affected by carbon monoxide from the stove.
Some dockers who were unloading bananas from the hold of
a motor ship, in which several small stoves had been burning to
keep the bananas at the right temperature, became ill and one of
them lost consciousness. The symptoms were: headache, weakness in the legs, loss of control.
(c) Poisoning by Carbon Dioxide (Heating or Refrigerating of Cargo)
Sometimes, if the cargo has been on board for a long time or
has become more or less heated, fermentation may have started
and it has often proved dangerous to enter the hold before it has
been well ventilated.
On the other = hand, when perishable cargo is refrigerated by
means of so-called "dry ice" (solidified carbon dioxide) the hold
may become partly or entirely filled with carbon dioxide gas; and
unless special precautions are taken the dockers unloading the
cargo will be exposed to a very serious danger of asphyxiation.
An accident of this kind occurred in 1937 in New York where
four dockers died and two others, together with a mate and a
deck hand, were removed unconscious to a hospital after entering
the hold of a fruit ship in which dry ice had been used as a refrigerant.
(d) Vapours from the Holds, etc., of Ships that have Carried Liquid
Cargo, such as Gasoline or Benzol
It is well known that the vapours from petroleum products
and benzol are very dangerous; they may cause intoxication, and if
their flash point is below, a certain temperature (usually taken as
65.6°C) they may explode.
(e) Emanations from Ship's Paint in Spaces that have been Closed
for a Long Time or are Difficult to Ventilate, e.g. Double Bottoms,
Tanks
The dangers mentioned under (d) and (e) have been well explored. In addition to testing for gas by sampling or the use of a
gas detector, adequate ventilation is an important precaution. " In
spite of precautions, however, accidents still occur and the utmost
prudence should always be displayed.

104

SAFETY IN DOCK WORK

(f) Produce of Vegetable Origin (Stomach Disorders)
Cases are known of illness among transport workers due to
eating kratok, rangoon, calabar or castor beans, bitter peach and
apricot kernels and bitter almonds (stomach and intestinal disorders, collapse).
The highly dangerous prussic acid may form in bitter kernels.
Twenty castor beans may prove fatal to an adult; two children
of a lighterman died after eating some of these beans.
Dried copra may give off irrespirable gases, especially at tropical
temperatures, and several casualties among coolies are known to
have been due t o this cause.
Turpentine leaking from barrels or drums may give off dangerous
vapours which cause giddiness and loss of consciousness; it is especially dangerous when a man feels ill and tries to leave the hold by
climbing up the hold ladder. Severe injuries have resulted from
falls from ladders in such circumstances.
A tallyman who happened to get a very slight quantity of nicotine in his mouth when sampling the cargo became dangerously ill.
(g) Lead (Ethyl

Fluid)
a

Up to now no accidents have occurred on board ship with
this cargo, but, as it is being conveyed in steadily increasing quantities, there should be adequate supervision of the precautions taken
during loading and unloading.
In the United States and in the Netherlands, the precautions
are as follows:
(1) Special inspection of the gear before unloading;
(2) Use of a tray for unloading;
(3) As an extra precaution, the tray is enclosed in a strong net
of steel or manilla rope fixed on the runner hook ;
(4) Exercise of the utmost care in loading or unloading.
It should be borne in mind that these dangerous goods need not
always be feared, the degree of risk depending on the circumstances.
T h e very disagreeable consequences of working with pitch, for
instance, depend to a large extent on the composition of the pitch
b u t perhaps to a still larger extent on the sun and the wind. For
d u s t and gases in general, ventilation and the degree of concentration
are very important factors.
If the goods here considered are packed in drums, barrels, casks,
bags, sacks, etc., their condition is a determining factor, and the
danger may be reduced or even be absent entirely when the containers are in good condition.

DISEASES, HARMFUL SUBSTANCES

105

On the other hand, the manner in which the goods are discharged
or loaded, and the fixed arrangements on board (for instance, small
coamings, sharp edges, etc.) may easily spoil the condition of bags
and sacks. For example, on an'old ship loaded with nitrate of lime
in special double jute and paper bags, no less than 52 bags were
damaged and their contents were strewn all over the hold during
hoisting.
The workers had a very disagreeable time with this cargo, which
was not at all the case on another ship from which a similar cargo
was discharged but where the fixed arrangements on board were
modern and better.
Paper bags should be kept dry : wet spots may cause holes and
tears.

Fig. 94

It would take too long to indicate in detail what should be done
when handling every dangerous commodity in every . conceivable
circumstance, but the following general precautions against these
dangers may be taken, separately or in combination:
(1) Allow short interruptions of work to enable the workmen
to breathe fresh air.

106

SAFETY IN DOCK WORK

(2) Work in two shifts, relieving each other every half hour.
(3) Use gas masks, respirators, wet sponges, coverings for face
and neck, gloves; fig. 94 shows the unloading of ground basic slag.
(4) Rub bare parts of skin with talcum powder, vaseline clay,
etc.
(5) Do not load or unload during sunshine or wind but only at
night.
(6) Handle goods very carefully and never throw bags and sacks
below.
(7) Ventilate holds and tanks as well as possible.
(8) Never rest or sleep in a closed room, especially when a coal
stove is burning.
(9) Do not enter holds or compartments without a safety belt
unless it has been ascertained that no danger exists.
(10) Do not enter silo bins in grain elevators without taking the
same precautions.
(11) Never use fire and never smoke in the neighbourhood of
flammable or explosive vapours and goods.
(12) Never eat or drink any of the cargo.
(13) Always keep a first-aid box ready for immediate use; when
there is a risk of suffocation (fire on board, working in double
bottom or tanks, unloading of goods which have been on fire) an
oxygen apparatus should be kept ready for use.
(14) When handling fruit such as bananas, be careful to keep
clear of snakes and other pests that may be hidden in the fruit.

Fig. 95

(15) Never touch dead rats with bare or even covered hands,
but use a pair of tongs.

DISEASES, HARMFUL SUBSTANCES

107

(16) Wash thoroughly with soap after finishing the work.
(17) Ask the doctor's advice immediately a pustule appears,
especially after working with hides, wools and bones.
(18) Give the workmen who work in dust an allowance of milk
or other suitable beverage in order to protect the mucous membranes of the throat. Milk, moreover, tends to promote physical
well-being in general, and people who are fit are less liable to disease
than those who are not.
These beverages, however, are by no
means an antidote; other health measures must not be neglected.
Fig. 95 illustrates the precautions mentioned under 3 for dockers
entering a hold to sweep up whale-oil residue.

§4.—Suffocation and Burns
Other suffocations and burns than those due to the causes
mentioned in §2 and §3 have often occurred, for instance owing to:
(a) Fire (e.g. spontaneous ignition of celluloid, copra, films,
matches, sulphur, cotton, ignition of flammable vapours);
(b) Explosions (e.g. of metal containers of compressed gases,
explosives, methane gas given off by certain "gassy" coals,
etc.);
(c) Drowning (special precautions should be taken against
drowning in oil tanks on board cargo ships) ;
(d) Gases escaping from refrigerating installations and cold
storage plant;
(e) Bites of insects, snakes and pests in general.

§5.—The Carrying of Heavy Weights
The carrying of heavy weights has also resulted in physical
injuries to dock workers and it would therefore be useful to have
an internationally recognised maximum weight of load to be handled
manually. However, the progress of mechanisation of dock labour
has eliminated a great part of this work.

CHAPTER

PSYCHOTECHNICAL APTITUDE TESTS
In several industries psychotechnical research has become a
commonplace, and the value of such research is by now generally
recognised, not only for promoting efficiency, but also, and not
least, for preventing accidents.
Dock work has become gradually more and more mechanised;
its tempo has been very much accelerated and it has been found
that for supervisors, crane and truck drivers, winch drivers, signallers, etc., an initial psychotechnical test is very useful. It seems
even not improbable that in future the aptitude of ordinary dockers
for their work will also be subjected to a test of this kind.
Some years ago the Scheepvaart-Vereeniging Zuid (Shipping
Federation) at Rotterdam established a psychotechnical laboratory
under the superintendence of a specialised medical practitioner.

PART II

Legislation concerning Dock Work

INTRODUCTORY NOTE
Safety in dock work is a matter that has received much attention from rule-making authorities. Several countries have issued
national or regional regulations in this matter and there are also
a number of voluntary safety codes in operation. International
regulations are embodied in the Convention (No. 32) concerning
the protection against accidents of workers employed in the
loading and unloading of ships, adopted by the International
Labour Conference in 1932, and the Convention (No. 27) concerning the marking of the weight oh heavy packages transported by
vessels, adopted by the International Labour Conference in 1929.
The present Part gives the text of these Conventions, the relevant
statutory regulations of Australia, Chile, Germany, Great Britain,
Portugal and Sweden, and voluntary safety codes in operation in
the United States. These texts may be considered to provide good
examplesof the rules that have been found necessary for the prevention of accidents to dock workers.

INTERNATIONAL
Convention (No. 32) concerning the Protection against Accidents of Workers Employed in Loading or Unloading Ships
(Revised 1932)
The General Conference of the International Labour Organisation of the League of Nations,
Having been convened at Geneva by the Governing Bod)'
of the International Labour Office, and having met in its Sixteenth Session on 12 April 1932, and
Having decided upon the adoption of certain proposals
with reg*ard to the partial revision of the Convention concerning the protection against accidents of workers employed in
loading or unloading ships adopted by the Conference at its
Twelfth Session, which is the fourth item on the agenda of the
Session, and
Considering that these proposals must take the form of a
Draft International Convention,
adopts, this twenty-seventh day of April of the year one thousand
nine hundred and thirty-two, the following Draft Convention for
ratification by the Members of the International Labour Organisation, in accordance with the provisions of Part XIII of the Treaty
of Versailles and of the corresponding Parts of the other Treaties
of Peace:
ARTICLE

For the purpose of this Convention:
(1) The term "processes" means and includes all or any part
of the work performed on shore or on board ship of loading or unloading any ship whether engaged in maritime or inland navigation, excluding ships of war, in, on, or at any maritime or inland
port, harbour, dock, wharf, quay or similar place at which such
work is carried on; and
(2) The term "worker" means any person employed in the
processes.
ARTICLE 2

Any regular approach over a dock, wharf, quay or similar
premises which workers have to use for going to or from a working place at which the processes are carried on and every such
working place on shore shall be maintained with due regard to the
safety of the workers using them.

LEGISLATION:

INTERNATIONAL

113

In particular,
(1) Every said working place on shore and any dangerous
parts of any said approach thereto from the nearest highway
shall be safely and efficiently lighted;

in use at the date of the ratification of this Convention, if the actual
measurements are not more than 10 per cent, less than the measurements specified in the said paragraph (4).
ARTICLE 3

(1) When a ship is lying alongside a quay or some other vessel
for the purpose of the processes, there shall be safe means of access
for the use of the workers at such times as they have to pass to or
from the ship, unless the conditions are such that they would not
be exposed to undue risk if no special appliance were provided.
(2) The said means of access shall be:
(a) Where reasonably practicable, the ship's accommodation ladder, a gangway or a similar construction ;
(b) In other cases a ladder.
(3) The appliances specified in paragraph (2) (a) of this Article

that the appliances specified in the Article are not required for
the safety of the workers.
(b) The provisions of this Article shall not apply to cargo
stages or cargo gangways when exclusively used for the processes.
(6) Workers shall not use, or be required to use, any other
means of access than the means specified or allowed by this Article.
ARTICLE; 4

When the workers have to proceed to or from a ship by water
for the processes, appropriate measures shall be prescribed to
ensure their safe transport, including the conditions to be complied
with by the vessels used for this purpose.
ARTICLE 5

(1) When the workers have to carry on the processes in a
hold the depth of which from the level of the deck to the bottom
of the hold exceeds 5 feet (1.5 m), there shall be safe means of
access from the deck to the hold for their use.
(2) The said means of access shall ordinarily be by ladder,
which shall not be deemed to be safe unless it complies with the
following conditions: •
(a) Provides foothold of a depth, including any space behind the ladder, of not less than 4 ^ inches (11.5 cm)
for a width of not less than 10 inches (25 cm) and a
firm handhold ;
(b) Is not recessed under the deck more than is reasonably
necessary to keep it clear of the hatchway;
(c) Is continued by and is in line with arrangements for
secure handhold and foothold on the coamings (e.g.
cleats or cups) ;
(d) The said arrangements on the coamings provide foothold of a depth, including any space behind the said
arrangements, of not less than 4J^ inches (11.5 cm)
for a width of not less than 10 inches (25 cm) ;
(e) If separate ladders are provided between the lower
decks, the said ladders are as far as practicable in line
with the ladder from the top deck.

LEGISLATION: INTERNATIONAL

115

Where, however, owing to the construction of the ship, the
provision of a ladder would not be reasonably practicable, it shall
be open to the competent authorities to allow other means of
access, provided that they comply with the conditions laid down
in this Article for ladders so far as they are applicable.
In the case of ships existing at the date of the ratification of
this Convention the measurement requirements of subparagraphs
(a) and (d) of this paragraph shall be deemed to be complied with,
until the ladders and arrangements are replaced, if the actual
measurements are not more than 10 per cent, less than the measurements specified in the said subparagraphs (a) and (d).
(3) Sufficient free passage to the means of access shall be left
at the coamings.
(4) Shaft tunnels shall be equipped with adequate handhold
and foothold on both sides.
(5) When a ladder is to be used in the hold of a vessel which
is not decked it shall be the duty of the contractor undertaking
the processes to provide such ladder. It shall be equipped at the
top with hooks or with other means for firmly securing it.
(6) The workers shall not use, or be required to use, other
means of access than the means specified or allowed by this Article.
(7) Ships existing at the date of ratification of this Convention shall be exempt from compliance with the measurements
in paragraph (2) (a) and (d) and from the provisions of paragraph
(4) of this Article for a period not exceeding four years from the
date of ratification of this Convention.
ARTICLE 6

(1) While the workers are on a ship for the purpose of the
processes, every hatchway of a cargo hold accessible to the workers
which exceeds 5 feet (1.5 m) in depth from the level of the deck
to the bottom of the hold, and which is not protected to a clear
height of 2 feet 6 inches (75 cm) by the coamings, shall, when
not in use for the passage of goods, coal or other material, either
be securely fenced to a height of 3 feet (90 cm) or be securely
covered. National laws or regulations shall determine whether
the requirements of this paragraph shall be enforced during meal
times and other short interruptions of work.
(2) Similar measures shall be taken when necessary to protect
all other openings in a deck which might be dangerous to the
workers.
ARTICLE 7

When the processes have to be carried on on a ship, the means
of access thereto and all places on board at which the workers
are employed or to which they may be required to proceed in
the course of their employment shall be efficiently lighted.
The means of lighting shall be such as not to endanger the
safety of the workers nor to interfere with the navigation of other
vessels.

116

SAFETY IN DOCK WORK
ARTICLE 8

In order to ensure the safety of the workers when engaged
in removing or replacing hatch coverings and beams used for
hatch coverings,
(1) Hatch' coverings and beams used for hatch coverings shall
be maintained in good condition;
(2) Hatch coverings shall be fitted with adequate hand grips,
having regard to their size and weight,-unless the construction
of the hatch or the hatch coverings is of a character rendering
the provision of hand grips unnecessary;
(3) Beams used for hatch coverings shall have suitable gear
for removing and replacing them of such a character as to render
it unnecessary for workers to go upon them for the purpose of
adjusting such gear;
(4) All hatch coverings and fore-and-aft and thwart-ship beams
shall, in so far as they are not interchangeable, be kept plainly
marked to indicate the deck and hatch to which they belong and
their position therein;
(5) Hatch coverings shall not be used in the construction of
cargo stages or for any other purpose which may expose them
to damage.
ARTICLE 9

Appropriate measures shall be prescribed to ensure that no
hoisting machine, or gear, whether fixed or loose, used in connection therewith, is employed in the processes on shore or on
board ship unless it is in a safe working condition.
In particular:
(1) Before being taken into use, the said machines, fixed gear
on board ship accessory thereto as defined by national laws or
regulations, and chains and wire ropes used in connection therewith, shall be adequately examined and tested, and the safe working load thereof certified, in the manner prescribed and by a competent person acceptable to the national authorities;
(2) After being taken into use, every hoisting machine, whether
used on shore or on board ship, and all fixed gear on board ship
accessory thereto as defined by national laws or regulations shall
be thoroughly examined or inspected as follows:
(a) To be thoroughly examined every four years and inspected every twelve months: derricks, goose necks,
mast bands, derrick bands, eyebolts, spans and any
other fixed gear the dismantling of which is specially
difficult;
{b) T o be thoroughly examined every twelve months: all
hoisting machines (e.g. cranes, winches), blocks,
shackles and all other accessory gear not included in (a).
All loose gear (e.g. chains, wire ropes, rings, hooks) shall be
inspected on each occasion before use unless they have been inspected within the previous three months.

LEGISLATION: INTERNATIONAL

117

Chains shall not be shortened by tying knots in them and
precautions shall be taken to prevent injury to them from sharp
edges.
A thimble or loop splice made in any wire .rope shall have at
least three'tucks with a whole strand of rope and two tucks with
one half of the wires cut out of each strand; provided that this
requirement shall not operate to prevent the use of another form
of splice which can be shown to be as efficient as the form hereby
prescribed.
(3) Chains and such similar gear as is specified by national
laws or regulations (e.g. hooks, rings, shackles, swivels) shall,
unless they have been subjected to such other sufficient treatment as may be prescribed by national laws or regulations, be
annealed as follows under the supervision of a competent person
acceptable to the national authorities:
(a) In the case of chains and the said gear carried on board ship:
(i)

Half inch (12.5 mm) and smaller chains or gear in
general use once at least in every six months;
(ii) All other chains or gear (including span chains but
excluding bridle chains attached to derricks or masts)
in general use once at least in every twelve months;
Provided that in the case of such gear used solely on cranes and
other hoisting appliances worked by hand, twelve months shall be
substituted for six months in subparagraph (i) and two years for
twelve months in subparagraph (ii);
Provided also that, if the competent authority is of opinion that
owing to the size, design, material or infrequency of use of any of
the said gear the requirements of this paragraph as to annealing
are not necessary for the protection of the workers, it may, by certificate in writing (which it may at its discretion revoke), exempt
such gear from the said requirements subject to such conditions as
may be specified in the said certificate.
(b) In the case of chains and the said gear not carried on board
ship:
Measures shall be prescribed to secure the annealing of
the said chains and gear.
(c) In the case of the said chains and gear whether carried on
board ship or not, which have been lengthened, altered or
repaired by welding, they shall thereupon be tested and reexamined.
(4) Such duly authenticated records as will provide sufficient
prima facie evidence of the safe condition of the machines and
gear concerned shall be kept, on shore or on the ship as the case
may be, specifying the safe working load and the dates and results
of the tests and examinations referred to in paragraphs (1) and
(2) of this Article and of the annealings or other treatment referred to in paragraph (3).

118

SAFETY IN DOCK WORK

Such records shall, on the application of any person authorised for the purpose, be produced by the person in charge thereof.
(5) The safe working load shall be kept plainly marked on
all cranes, derricks and chain slings and on any similar hoisting
gear used on board ship as specified by national laws or regulations. The safe working load marked on chain slings shall either
be in plain figures or letters upon the chains or upon a tablet or
ring of durable material attached securely thereto.
(6) All motors, cogwheels, chain and friction gearing, shafting, live electric conductors and steam pipes shall (unless it can
be shown that by their position and construction they are equally
safe to every worker employed as they would be if securely fenced)
be securely fenced so far as is practicable without impeding the
safe working of the ship.
(7) Cranes and winches shall be provided with such means
as will reduce to a minimum the risk of the accidental descent
of a load while in process of being lifted or lowered.
(8) Appropriate measures shall be taken to prevent exhaust
steam from and, so far as practicable, live steam to any crane
or winch obscuring any part of the working place at which a worker
is employed.
(9) Appropriate measures shall be taken to prevent the foot
of a derrick being accidentally lifted out óf its socket or support.

defects to those who are responsible for the material (port owner,
ship's master or other).
Foremen and their Responsibilities
2. (a) In loading and unloading work the foreman shall not
undertake or be required to undertake simultaneous supervision
over more than six working gangs. Further, he may exercise supervision over more than one ship only when the ships are in the
immediate vicinity of one another.
If in loading and unloading work on one and the same ship,^
more than six working gangs are simultaneously employed, a
suitable worker (underforeman) shall be appointed to assist the
foreman in supervising the work.

185

{b) The foreman shall see:
that the material used for loading and unloading work is
in a reliable condition;
that defective material is taken out of use;
that where the defects are of a nature to endanger safety,
the work is interrupted until the defects are removed.
(c) If loading and unloading work has to be done in shifts, the
foreman as well as the workers should be relieved so that he can
enjoy the necessary rest.
(d) Persons belonging to the vessel's crew and who, in so far
as concerns stevedoring, perform a foreman's duties, shall during
these operations comply with the above provisions concerning
foremen.
Winch and Crane Attendants, Signalmen, Hatch Foremen and
their Duties
3. (a) As winch or crane attendants, hatch foremen or signalmen there shall only be employed persons who, by reason of their
experience and personal qualifications, are fitted to perform such
work. Such persons shall, inter alia, have normal eyesight and
hearing and in the case of hatch foremen also possess the necessary
vocal powers. For such work when performed independently, and
in so far as it is pot to be deemed to be incumbent on the ship's
crew, persons under the age of 18 shall not be employed.
Note. The employment on the kinds of work in question, of persons whose
working capacity by reason of ill health or otherwise, is reduced or who d o not
understand Swedish, must therefore be avoided as far as possible, since the
safety of the other workers in very great measure 'depends on the entrusting of
such work to persons who are fitted for it.

(b) The hatch foreman shall carefully follow the loading and unloading work and be so placed that he can observe the course of
all the work. He shall give clear signals to the crane and winch
attendants in conformity with the signalling scheme (see Schedule
I) and in good time give warnings to the workers in the hold, in.
the barge or on the quays.
As a rule there shall be one hatch foreman for every gang.
For unloading work by means of cargo falls the hatch foremen
may, as a rule, be replaced by a so-called "dumper".
Note. Only exceptionally may a hatch foreman be'dispensed with, for example,
when there is no-one in the hold, or in the case of undecked vessels, barges, railway wagons, etc., where the crane or winch a t t e n d a n t has a clear view of the
workplace. With cranes, if the crane attendant has not the necessary view of the
workplace, a signalman may be necessary even if the hatch foreman can be dispensed with.
'

Lighting
4. A workplace on shore and the approach to it from the
nearest public way shall be provided with adequate and dazzlefree lighting.

186

SAFETY IN DOCK WORK

non-slippery as far as possible in some other way. If
the quay or wharf slopes outwards, a rail or toeboard
shall be installed at the outer edge.
(b) Goods shall not be so stored on the quay as to hinder
necessary access to gangways or other means of access
t o the vessel. As a rule, goods shall not be stored within
90 cm from the edge of the quay or wharf.
(c) If communication between ship and shore has to be
maintained by a rowing boat or a power-driven boat
less than 10 m in length that is not required to be provided with a passenger vessel certificate under the
Act concerning inspection of ships and on which no
passengers _ are conveyed against remuneration, the
employer who undertakes loading or unloading work
shall be bound to see that the transport of the workers
to and from the workplace is carried on in an adequate
manner and that the boats that are used for this purpose
are seaworthy and not overloaded.
In the case of longer-distance sea transport, especially during
the cold season, the workers shall be provided with the necessary
protection on board against wind and weather.
Note. If transport is effected by boats other than those mentioned in subparagraph (c) they shall be subject, as regards construction and equipment, to
those provisions of the Act concerning the inspection of ships and the regulations
under this Act that relate to passenger vessels (S.F., 1914, No. 349, etc.).

SAFETY IN DOCK WORK

(b) Shackle pins on topping lift and cargo blocks should be
checked to'see if pins have worked loose. Shackle pins
should be secured with seizing wire or key pins;
(c) Flooring of decks, docks, gangplanks, and passageways
should be examined for defects;
(d) Cargo booms should have approved capacity plainly
marked in a conspicuous manner and place, preferably
at the heel of the boom. In the absence of such marking, the shipowner shall supply the stevedore with a .
statement as to the capacity of the boom.
(2) When decks, gangways, ladders, docks, or other passageways are slippery due to ice, oil, grease, or other materials, an
adequate supply of salt, sand, or cinders should be provided and
used to prevent slipping and falling. If it is impractical to use
these anti-slip materials, safety lines should be rigged and a warning
sign should be conspicuously placed nearby "Danger, Slippery
Deck", and the condition corrected as soon as possible.

hatch, that hatch cover should be replaced or the open hatchway
should be properly guarded.
(5) When longshoremen are working through an opening of
one section in a hatch, the remaining beams that are left in should
be properly secured.
(6) When hatch covers or strongbacks are off, they should be
piled or placed on deck in such a position as not to interfere with
gangwaymen or others working or walking on deck of vessel. When
hatch covers are piled near open hatches, with coamings, covers
should be kept reasonably below the top of the coaming.
(7) Tween-deck hatch covers should be stowed at a safe
distance from coaming to prevent them from being thrown into
hold by a draft swinging under coamings.
(8) When gangwaymen make a flooring of hatch covers between
the coaming and sides of the vessel they should place them so as
to leave no space between the hatch covers and prevent a tripping
hazard.
(9) Any hatch covers or strongbacks which cannot be properly
placed, or are otherwise found defective, should be reported by the
longshoremen to foremen who should immediately advise proper
officer of ship.
(10) Hatch covers that are placed over beams resting on deck

The Safe Installation and Use of
Abrasive Wheels
Studies and Reports, Series F, Second Section (Safety), No. 9
This study directs attention to the dangers attending the greatly
increased use of manufactured abrasive wheels and indicates the
precautions which must be taken against accidents, and damage to
health through inhalation of dust.
The preliminary draft was made in 1932 by Mr. G. Stevenson
Taylor, O.B.E., H.M. Deputy Chief Inspector of Factories, London,
who also made a final revision after it had been considered and
amended by the I.L.O. Correspondence Committee on Accident
Prevention. Publication was delayed for financial reasons, and by
the outbreak of war. This delay has however proved advantageous, since it has enabled Mr. Stevenson Taylor to revise the
manuscript in the light of the experience of recent years and to
bring the technical part up to date on several important points.
