Which of the following is NOT considered a primary aspect of preventative maintenance?

Preventive maintenance focuses on actions taken to prevent equipment failures before they occur, thereby ensuring the longevity and efficiency of machinery. One of the key tenets of preventive maintenance is that it is proactive rather than reactive. Scheduled regular inspections, routine services based on time or usage, and long-term reduction of breakdown incidents all contribute to the ongoing upkeep and reliability of equipment.

Immediate response to equipment failure, however, does not align with the principles of preventive maintenance. Instead, it represents a reactive approach, addressing problems only after they have occurred. Preventive maintenance aims to anticipate and mitigate issues before they lead to failure, ensuring that machinery operates smoothly and minimizing downtime. This distinction is crucial for understanding effective maintenance strategies in utility operations.
