What should be implemented when a fire alarm system is out of order for an extended period?

When a fire alarm system is out of order for an extended period, implementing a fire watch is essential. A fire watch involves designating trained personnel to monitor the premises for signs of fire and ensure safety protocols are followed during the period when the automatic fire alarm system is unavailable. This manual oversight is crucial because it helps to quickly detect any potential fires and allows for immediate notification of the fire department, ensuring a timely response to emergencies.

A fire watch also involves maintaining communication with local authorities and conducting regular patrols throughout the building to ensure that all areas are safe. These measures provide a necessary level of safety and protection when the automated alarm system cannot perform its critical function.

The other options, while relevant in certain contexts, do not directly address the immediate need for a protective measure while an alarm system is non-operational. A temporary alarm system could be part of a solution, but it does not replace the necessity of a dedicated fire watch. Evacuation of the building is not a practical response to the situation unless there is an immediate threat. Emergency drills, while important for preparedness, do not provide real-time monitoring and safety assurance in the absence of a functional alarm system.
