Which type of maintenance is described as proactive in nature?

Preventive maintenance is characterized as proactive because it involves scheduled activities that are designed to prevent equipment failures before they occur. This type of maintenance is performed at regular intervals or according to metrics like operating hours to ensure that systems operate efficiently and reliably.

By anticipating potential issues and addressing them through regular inspections, servicing, and part replacements, preventive maintenance helps to minimize downtime and extend the life of equipment. This proactive approach contrasts with reactive maintenance, which occurs in response to equipment failures, lacking the foresight that preventive measures provide.

In summary, preventive maintenance is focused on maintaining equipment in good working condition and preventing failures, making it a proactive strategy essential for effective facility management in drinking water operations.
