Which sequence correctly lists the PMCS steps in the order they should be performed?

• A. During PMCS, Before PMCS, After PMCS
• B. After PMCS, Before PMCS, During PMCS
• C. Before PMCS, During PMCS, After PMCS
• D. Before PMCS, After PMCS, During PMCS

Answer: (C)

The sequence starts with preparation and readiness, then moves to the actual inspection, and ends with documenting and closing actions. In PMCS, you begin with Before PMCS to check that the equipment is set up correctly, is safe to operate, and you have all needed tools and documentation. Next comes During PMCS, where you systematically inspect and verify each component while the equipment is prepared for use. Finally, After PMCS covers the follow-up: recording results, noting any faults or needed repairs, and ensuring the equipment is properly marked or turned back ready for operation.

This order makes sense because you can’t responsibly inspect or operate something you haven’t prepared or verified as safe. If you started with During or After, you’d be attempting inspections or closing actions without first confirming readiness, which can miss safety checks or required documentation. The other sequences place steps in illogical order, whereas Before PMCS, During PMCS, After PMCS follows the natural flow from preparation to inspection to accountability.
