ELECTRICAL PREVENTIVE MAINTENANCE AND ITS ROLE IN PROMOTING SUSTAINABLE SYSTEM RELIABILITY IN INDUSTRIAL FACILITIES

This study evaluated the implementation and effectiveness of Electrical Preventive Maintenance (EPM) programs in industrial facilities using the 5Ms of Management Framework: Man, Machine, Method, Material, and Money, to determine challenges, their influence, and their role in achieving sustainable system reliability. Data were gathered from 26 maintenance personnel in a PEZA-accredited industrial park through structured survey questionnaires and analyzed using descriptive statistics, supported by qualitative responses and guided by the 5Ms framework. Results revealed that overall, EPM was partially implemented. The Method and Machine dimensions were rated fully implemented, indicating that planning, scheduling, and technical maintenance procedures were generally in place. In contrast, the Man, Material, and Money dimensions were rated partially implemented, reflecting gaps in workforce training and certification, resource availability, and budget allocation for EPM. In the Philippine Economic Zone Authority (PEZA), compliance with EPM is monitored mainly through the Certificate of Electrical Inspection (CEI), which requires submission of electrical test reports and safety certifications in accordance with the Philippine Electrical Code (PEC). However, this compliance does not provide comprehensive guidance for sustained preventive maintenance implementation, highlighting the need for a localized and sustainability-oriented EPM framework. The findings emphasize the importance of structured training programs, standardized documentation systems, proactive resource planning, and dedicated maintenance budgets to strengthen operational reliability and ensure long-term industrial sustainability.
