  Design and Establishment of an Integrated Safety andPreventive Maintenance System for Improving Safety Indices

  Background and aims: Accident analysis shows that one of the main reasons of 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 can potentiallylead to the improvement of organizational performance.

  Methods: Firstly, safety and maintenance indices were determined and related values ​​were measured. I In order to promote the selected indicators, an integrated safety and preventive maintenance system were designed and implemented. Finally, after six months, values of selected indices were re-measured. The changes in values of indices were assessed using the Wilcoxon test .

  Results: Our results showed that, following the intervention,the improvement of reliability, accessibility, repetition rate and events severity rate indicators was statistically significant (p-value ≤ 0.05).

  Conclusion: This system predicts the types of defects, plans and designs required operation to prevent defects occurrence. As a result, it can potentially lead to safety, equipment and organizational performanceimprovement .
