Should emergency lighting be included in a building design?

Usually, the code applicable to the design of the building—like the International Building Code (IBC), for example—sets the requirement to include an emergency lighting system as an element of the project design. The building code, alternatively, might invoke NFPA 101: Life Safety Code.

How long do you need emergency lighting?

Emergency lighting is required throughout the path of egress and must operate for a minimum of 90 minutes. (See NFPA® 101® Life Safety Code®.) Stairs, aisles, corridors, ramps, escalators and passageways leading to safety must be continuously illuminated for a minimum of 90 minutes.

What are the NFPA requirements for emergency lighting?

For example, in addition to IBC building general type classifications, the IBC Type I-2 for hospitals have additional emergency lighting requirements as outlined in NFPA 99, NFPA 110, and NFPA 70 Article 517.63, which require supplemental battery-powered emergency lighting for anesthetizing locations.

Do emergency lighting systems need two sources of power?

Emergency lighting systems are also required to have two sources of power. The two sources may be two utility sources—preferably from two separate substations. Another option is a utility source and a storage battery or unit battery equipment—an option typically used in small commercial projects.
