Which of the following best describes preventive maintenance?

Preventive maintenance is best described as regular maintenance activities that are performed to reduce the risk of equipment failure. This approach is proactive, focusing on scheduled inspections, servicing, and upgrades intended to maintain equipment in optimal working condition and prevent unexpected breakdowns. By performing regular preventive maintenance, technicians can identify and address potential issues before they evolve into significant problems, thereby extending the life of the equipment, ensuring safety, and enhancing operational efficiency.

This concept contrasts with corrective maintenance, which occurs after a device has already failed, emphasizing the importance of maintenance strategies that prioritize equipment reliability and safety through routine checks and interventions. Regular maintenance activities also include monitoring equipment performance over time, although that is more aligned with predictive maintenance strategies.
