Preventive maintenance is specifically designed to prevent equipment failures before they occur. This type of maintenance involves regular inspections, servicing, and the replacement of parts based on the manufacturer's recommendations or operational data. The goal is to ensure that equipment operates efficiently and to prolong its lifespan by addressing potential issues proactively.

By conducting preventive maintenance, operators can identify wear and tear on machinery and make necessary adjustments or repairs before a failure happens. This approach minimizes downtime, reduces repair costs, and enhances overall productivity within plant operations.

In contrast, reactive maintenance occurs after a failure has happened, addressing problems as they arise. Scheduled maintenance refers to routine servicing done at predetermined intervals but does not necessarily focus on preventing failures—it can be preventive or corrective based on the task. Corrective maintenance deals with repairs needed to fix issues that have already manifested. So, while all these types of maintenance play roles in equipment management, preventive maintenance specifically targets the prevention of failures.
