Abstract:

Emergency lighting must be provided IAW NFPA 101, Chapter 5, Section 5-9. Normally emergency lighting is required only for designated stairs, aisles, corridors, ramps, escalators, and passageways leading to an exit. Interior rooms and windowless rooms generally do not require emergency lighting unless they meet the definition of a Windowless Structure in NFPA 101, Chapter 30 Section 30-1.3.5. Mechanical rooms, telephone equipment rooms, and similar utility spaces generally do not require emergency lighting. Emergency lighting in facilities provided with a stand-by-electric generator should be powered by the generator. Such generators must be installed, tested, and maintained in accordance with NFPA 110, Emergency and Standby Power Systems.
