Preventive maintenance is a proactive approach to maintaining equipment and systems to prevent unexpected failures. It involves regular inspections, servicing, and repairs based on a schedule rather than waiting for a breakdown. This practice helps extend the lifespan of machinery and reduces the risk of costly downtime. By implementing preventive maintenance, organizations can identify potential issues early and address them before they escalate. Common tasks include changing filters, lubricating moving parts, and checking for wear and tear. This strategy is widely used in various industries, including manufacturing, transportation, and facility management, to ensure smooth operations and enhance safety.
