My fat doesn't effect others- building maintenance eddition I work in a transport hub. We have multiple escalators to ensure people can move around the area quickly. Now those escalators have maintenance schedule and an expected life. The facility uses this to determine when they can reasonably expect to have to replace them due to wear. Makes sense right? The problem is that when the schedule was put together (only 10 years ago) they calculated by average numbe of patrons at an average weight. The average weight of the average person has risen enough (also no ones uses the goddamn stairs that run along side every single escalator, so more people on them too)in the last ten years that the escalator will likely need to be replaced at least 7 years ahead of what was originally projected.
