The International Building Code (IBC) specifically requires emergency lighting in electrical rooms, fire command centers, fire pump rooms, and “electrical equipment rooms”. Internal rooms, bathrooms, and storage areas larger than a broom closet require emergency. . In Class 6 or 9b buildings, emergency lighting is required in every room or space with public access, and open areas and rooms must provide sufficient illumination for occupants to feel safe and move towards a safer place. UL 924 is a product safety standard outlining requirements for equipment used in emergency situations. They must be illuminated to at least 54 lux and exit lights are often required to be red. In the case of a power outage or other emergency, lights must be hardwired and have a backup. . These standards define where emergency illumination must be installed, brightness levels for means of egress, required runtime durations, exit sign specifications, and testing protocols that keep systems operational when lives depend on them. Emergency luminaires are connected to dedicated emergency circuits. . With the recent release of the 2018 Edition of the National Fire Protection Association (NFPA) National Life Safety Code 101, which became effective on September 6, 2017, now is a good time to review your emergency lighting system to ensure that it is still compliant with the newest updates.
