What type of maintenance is concerned with immediate correction of failures?

The focus of corrective maintenance is specifically on addressing and rectifying failures that have already occurred. This type of maintenance is reactive; it involves identifying the cause of a malfunction and performing the necessary repairs to restore equipment to its operational state. Corrective maintenance becomes crucial when equipment fails unexpectedly, and immediate action is required to minimize downtime and restore functionality.

This approach is a key aspect of a comprehensive maintenance strategy, as it ensures that any issues are promptly resolved, allowing operations to continue with minimal interruption. In contrast, preventive maintenance involves regular servicing to prevent failures, routine maintenance refers to regularly scheduled tasks, and scheduled maintenance outlines planned maintenance activities based on time or usage rather than immediate need. Each of these plays a role in an overall maintenance program, but only corrective maintenance directly deals with the immediate response to equipment failures.
