Which of the following actions is a preventive maintenance strategy?

The selected answer, which focuses on performing regular inspections and servicing, is a prime example of a preventive maintenance strategy because it directly aims to identify and address potential issues before they lead to equipment failure. Preventive maintenance involves scheduled tasks, such as lubrication, cleaning, adjustments, and replacements based on usage and wear, rather than on the basis of equipment breakdowns.

By engaging in regular inspections and servicing, an organization effectively extends the lifespan of its equipment, maintains optimal performance, and minimizes the risk of unexpected downtimes or costly repairs. This proactive approach not only ensures that equipment operates efficiently but also upholds safety standards and enhances overall productivity.

In contrast, actions such as waiting for equipment to fail before fixing it, ignoring minor issues, or only replacing parts when they are visibly damaged reflect reactive or neglectful maintenance strategies that can lead to increased wear, higher costs, and reduced equipment reliability over time.
