Which maintenance practice involves inspecting equipment to prevent failures before they occur?

The correct answer is preventive maintenance because it specifically focuses on regular inspections and maintenance tasks aimed at preventing equipment failures from happening. By carrying out scheduled maintenance activities, such as lubricating moving parts, tightening loose bolts, or replacing worn components, technicians can identify potential issues before they escalate into significant failures. This proactive approach minimizes the risk of unexpected downtime and extends the operational lifespan of equipment.

Preventive maintenance involves a systematic approach that takes into account historical data, maintenance schedules, and manufacturer recommendations, ensuring that all necessary checks and actions are performed regularly. This process not only enhances reliability and efficiency but also helps in budgeting and planning for future maintenance needs, ultimately leading to cost savings and safety improvements in operations.
