2. Preventive maintenance is a schedule of plannedmaintenance actions aimed at the prevention ofbreakdowns and failures. The primary goal of preventive maintenance is to preventthe failure of equipment before it actually occurs. Designed to: Preserve and enhance equipment reliabilityby replacing worn components Ensure machine failures are not the cause for workplacemishaps. 3. A written preventive and predictive maintenancesystem must be in place . Equipment must be replaced or repaired on aschedule, following manufacturersRecommendations. Documented records of maintenance and repairsmust be kept. The system must include maintenance of hazardcontrols such as machine guards, exhaust ventilation,mufflers, control circuits and devices, etc. 4. A PM system aligns with a safety management program to: Prevent injuries caused by malfunctioning equipment. Increase automation Reduce losses due to production delays Improve quality Just-in-time manufacturing Provides a more organized work environment. 5. Some advantages of a PM system include: Reduced production downtime. Conservation of assets and increased life .expectancy of assets (both machine and human) Ensuring all equipment safety features arefunctioning properly. Reduced cost of repairs by reducing secondary failures. Quality products . Timely, routine repairs circumvent fewer large-scalerepairs. 6. Things to consider after completing a maintenanceoperations: Ensure equipment meets manufacturers specification. Review job hazard analysis (JHA) to ensure equipmentalterations or equipment maintenance did not introduce newhazards. Conduct machine checks to ensure all features, especiallysafety devices, are functioning properly. Ensure employees are aware of any changes toequipment and/or operating procedures. 7. Three keys for a successful PM system: Scheduling: Should be automated to the maximumextent possible. Execution: Should be done before an actual breakdown occurs. Quality: Should have a formal process for checkingthe quality of repairs. 8. In this presentation you learned about Preventive Maintenance Program components. Reasons for the PM system. Advantages of a PM system. Successful PM system. 9. GUIDED BY :
