When is it required to perform PMCS on equipment?

Performing Preventive Maintenance Checks and Services (PMCS) on equipment is essential at various stages of operation to ensure its safety, reliability, and operational effectiveness. Conducting PMCS before operations helps identify any existing issues that could impede functionality. This pre-operation check is crucial for ensuring that the equipment is ready and safe for use.

During operations, ongoing checks may be necessary to monitor equipment performance, allowing for immediate detection of any problems that arise while in use. This proactive approach helps prevent equipment failure or accidents.

After operations, performing PMCS helps assess any wear and tear that may have occurred during use. This post-operation check allows for timely maintenance, ensuring that equipment remains in good condition for future use.

Thus, the correct answer indicates the comprehensive need to conduct PMCS checks before, during, and after operations to maintain equipment reliability and safety throughout its lifecycle.
