Design and Establishment of an Integrated Safety and Preventive Maintenance System for Improving Safety Indexes

Accident analysis shows that one of the main reasons for accidents is non-integration of maintenance units with safety. Merging these two processes through an integrated system can reduce accidents, diseases, and environmental pollution. These issues lead to improvement in organizational performance. Firstly, safety and maintenance indices and values were measured. Then, in order to promote the selected indicators, an integrated safety and preventive maintenance system were designed and implemented. Finally, after six months, values of these indices were re-measured. The changes in indices were assessed using the Wilcoxon test. After the intervention, the results show that improvement in reliability, accessibility, repetition rate and events severity rate indicators is statistically significant (p-value ≤ 0.05). This system predicts the types of defects, plans and designs required operation to prevent defects occurrence. As a result, this can lead to safety, equipment and organizational performance improvement.
