Which of the following tasks is NOT part of routine maintenance?

The task that is not part of routine maintenance is related to repairing damage from an accident. Routine maintenance is generally focused on preventative care to ensure that equipment, such as fire apparatus, operates safely and efficiently. This includes tasks like checking fluid levels and testing alarm systems, which are regular inspections meant to identify and address potential issues before they become significant problems.

Repairing damage from an accident, however, involves corrective maintenance rather than routine maintenance. It is an unforeseen event that requires specific repairs to restore the apparatus to working condition, and it occurs outside the usual maintenance protocols that are part of regular operational procedures. Thus, while all maintenance tasks are important for the overall functionality and safety of fire apparatus, only those that are preventative or routine should be classified as such.
