What does preventive maintenance involve?

Preventive maintenance involves actions taken to ensure that equipment and systems are functioning effectively and to reduce the likelihood of failures. This includes tasks that are performed before any deterioration occurs, effectively extending the lifespan of the equipment and preventing unexpected downtime. By addressing minor issues before they escalate into major problems, organizations can save costs associated with repairs and lost productivity.

Routine checks of equipment also form part of preventive maintenance practices, but the core concept specifically emphasizes actions taken before issues arise, rather than simply monitoring performance. Repairing after failure reflects a reactive approach, which is contrary to the preventive maintenance philosophy. Additionally, while the replacement of old equipment can be a component of a broader maintenance strategy, preventive maintenance focuses on the upkeep and optimization of existing equipment rather than outright replacement.
