How quickly should the generator provide power to exit signs during an emergency?

The timeframe for a generator to provide power to exit signs during an emergency is critical for ensuring safety and effective evacuation. The correct timeframe is 10 seconds. This prompt response time is essential because in emergencies, such as a power outage or a fire, occupants need clear and immediate guidance to evacuate the building safely. Exit signs help direct people to exits, and a delay in power can create confusion and exacerbate panic.

A generator that activates exit signs within this timeframe ensures that they are illuminated quickly, allowing individuals in the building to recognize their escape routes without hesitation. The National Fire Protection Association (NFPA) and other safety guidelines emphasize the importance of having emergency lighting and exit signs operational as soon as possible in the event of a power failure, highlighting that a 10-second response aligns well with these safety protocols.
