In special hazard applications, audible alarms in the facility may be silenced.

• A. True
• B. False
• C. Only with manual release
• D. Only during maintenance

Answer: (A)

In special hazard systems, there is a controlled way to temporarily quiet audible alarms to allow maintenance or testing to proceed safely. The alarm control includes a silence function that authorized personnel can use to suppress the sound for a limited time, while the system continues to monitor for hazards and keeps other indicators (like visual signals or remote annunciation) active. The silencing is not a free-for-all; it is time-limited and requires proper authorization so that a dangerous condition can still be detected and re-alerted if needed. This approach supports safe operations by reducing noise during work without eliminating the notice of a real hazard.
