Who must approve deferring an alarm?

• A. Operator
• B. NCOIC, ESS or vindicator NCO
• C. Supervisor
• D. Commanding Officer

Answer: (B)

Deferring an alarm is a controlled exception to normal alarm response that requires formal approval to maintain accountability and safety. The person in charge of the area or the designated supervisory roles are the ones entrusted with this authority because they can assess the situation, weigh risks, and ensure the action is properly documented in the system. This keeps the chain of command intact and provides an auditable record of why the alarm was deferred and for how long.

The operator does not have the authority to grant a deferral, since they are the one responding to the alarm rather than authorizing changes to the response procedure. A supervisor might review or oversee; however, the policy specifies that approval comes from the NCOIC, ESS, or vindicator NCO. The commanding officer is too high-level for routine deferrals, reserved for exceptional circumstances or overarching policy decisions.
