What type of maintenance occurs when equipment fails?

Corrective maintenance is performed when equipment fails. This type of maintenance is reactive in nature, meaning that it addresses issues only after they have occurred. The primary goal of corrective maintenance is to restore the equipment to its operational condition as soon as possible following a breakdown. This often involves diagnosing the problem, repairing or replacing faulty components, and ensuring that the equipment is running smoothly again.

In contrast, preventive maintenance involves regular and routine actions taken to prevent equipment failures before they occur. Predictive maintenance uses data-driven insights to predict when equipment will fail, allowing for maintenance to be performed just in time to avoid breakdowns. Proactive maintenance focuses on identifying and eliminating the root causes of equipment failures to improve reliability and performance over time.

Thus, it is clear that the type of maintenance specifically associated with addressing equipment failures directly is corrective maintenance.
