Which of the following best describes the type of maintenance that focuses on proactive maintenance to prevent breakdowns?

The concept of maintenance that emphasizes proactive measures to avert equipment failures is known as preventive maintenance. This approach involves scheduled inspections and services designed to maintain equipment and systems in optimal working condition, thereby reducing the likelihood of unexpected breakdowns.

Preventive maintenance aims to extend the lifespan of assets and improve overall efficiency by addressing potential issues before they result in equipment failure. Examples of preventive maintenance activities include regular servicing, cleaning, lubricating moving parts, and replacing worn components based on a predetermined schedule.

In comparison, corrective maintenance responds to issues after they occur, while maintenance prevention and breakdown maintenance do not align with the proactive focus of preventive maintenance. In maintenance prevention, there's an emphasis on designing out the possibility of failures, while breakdown maintenance typically refers to the reactionary measures taken in response to unplanned outages.
