What is the primary purpose of a preventive maintenance program in utility operations?

• A. To train staff only in safety drills
• B. To wait for breakdowns before repairing
• C. To proactively inspect and service equipment to prevent failures and extend life.
• D. To replace equipment yearly regardless of condition

Answer: (C)

Preventive maintenance centers on keeping equipment reliable by inspecting, servicing, and replacing parts before they fail. In utility operations, this means scheduling regular checks of critical assets—pumps, valves, switchgear, meters, generators—and performing tasks like lubrication, filter changes, calibration, belt or bearing replacements, and leak checks. This proactive approach catches wear or misalignment early, reduces the chance of unexpected outages, lowers repair costs, and helps extend the life of equipment. It also supports safety and regulatory compliance because equipment remains in good working condition. Waiting for a breakdown leads to outages and higher costs, while replacing equipment every year regardless of condition wastes resources; training alone in safety drills, though important, does not prevent equipment failures. So the proactive inspection and servicing that prevents failures and extends life is the primary purpose.
