Essence of Preventive Maintenance includes which of the following elements?

• A. Early identification; Replacement; Repair; Prevent failures
• B. Early identification
• C. Replacement and Repair
• D. Prevent Failures and Beyond

Answer: (A)

Preventive maintenance is about catching problems before they cause a failure and keeping equipment performing reliably. The strongest choice reflects a complete, proactive approach: identify potential issues early through inspections, tests, or condition monitoring; replace worn or critical components before they fail; and perform repairs as needed to restore and maintain performance. Together, these steps prevent failures and extend the life of instruments and systems. The other options miss parts of this approach: early identification alone doesn’t prevent breakdowns; focusing only on replacement and repair skips the proactive detection step; and a vague option like preventing failures and beyond lacks concrete actions to implement.
