Lubrication and other ______ maintenance activities should be checked daily to ensure they are being performed.

• A. Preventive
• B. Corrective
• C. Predictive
• D. Reactive

Answer: (A)

Preventive maintenance is about performing planned upkeep to keep equipment running smoothly and to prevent problems before they occur. Lubrication is a classic preventive task because proper lubrication reduces wear, heat, and the risk of unexpected failures. By checking daily that these activities are being performed, you ensure the maintenance plan is being followed and not neglected, which helps maintain reliability and reduce downtime. The other concepts involve fixing problems after they arise or relying on condition data to trigger work, rather than ensuring routine tasks are completed on schedule, so they don’t fit as well in this context.
