Who is required to perform PMCS?

• A. Every operator who is assigned a piece of equipment
• B. New operators only
• C. Supervisors
• D. Only maintenance personnel

Answer: (A)

PMCS stands for Preventive Maintenance Checks and Services, and the essential idea is that the person who will operate the equipment is responsible for ensuring it’s safe and ready before use. Performing PMCS before each operation helps catch issues early, verify that critical systems work, and prevent breakdowns or accidents.

This requirement applies to every operator assigned to a piece of equipment, not just new operators, not solely supervisors, and not only maintenance personnel. While new operators may be trained on how to do PMCS, and supervisors or maintenance staff may be involved in oversight or repairs, the part of the process that ensures the equipment is safe to use sits with the person who will operate it. If a deficiency is found, it should be addressed before the equipment is operated.

So the best answer is that every operator assigned to a piece of equipment is required to perform PMCS.
