By what time must time off requests be submitted to the OFF duty officer?

The correct answer is based on the common operational protocols within fire department practices regarding time off requests. Typically, fire departments establish specific times by which personnel must submit their requests for time off to ensure proper staffing and operational readiness.

In many departments, 0645 hours is the designated cutoff time for submitting these requests, as it allows the OFF duty officer adequate time to review the requests before the start of the daily shift. This practice ensures that any changes in staffing can be managed efficiently and that all personnel are informed well in advance about any adjustments to the roster.

The other times listed may either be too early or do not align with the operational procedure of most departments, which differentiates them from the correct submission time. Thus, the importance of adhering to this specific time is crucial for effective scheduling and maintaining optimal staffing levels within the department.
