Which of the following best describes Reactive Maintenance?

Reactive maintenance involves addressing problems after they occur rather than anticipating them. This approach focuses on responding to equipment failures and system breakdowns as they happen, making it essential in situations where immediate repair is needed to restore functionality. The primary characteristic of reactive maintenance is its unscheduled nature, where maintenance activities are performed in response to unexpected issues.

In contrast, planned repairs or preventative strategies aim to prevent issues before they arise, which is not the focus of reactive maintenance. Routine checks and services involve regular maintenance activities that help keep equipment operating smoothly, whereas regular audits of equipment efficiency assess ongoing performance but do not directly address immediate breakdowns. Thus, the description that captures the essence of reactive maintenance is the undertaking of unscheduled repairs following a failure or issue, making the chosen answer the most accurate representation.
