  • Fire emergency exit lights guide people to the nearest exit in the event of an emergency. Loss of electrical power and smoke buildup can greatly diminish visibility during a fire. Emergency exit lights increase your chances of escaping. Exit lights should be located at exit doors and strategically located along exit routes to lead people to safety. The Occupational Safety and Health Administration regulates the designation and marking of fire exits.

    Guidance

    The National Fire Protection Association covers exit signs, their use, and performance standards in the Life Safety Codes (NFPA 101).

    Significance

    Fire emergency exit lights must be self-illuminated or externally illuminated with a reliable light source. The lights serve as a guide to help building occupants find exits during an emergency

    Features

    Fire emergency exit lights must be illuminated independent of the building's electrical service. The illumination should be bright enough for people to see from floor level should they have to crawl to an exit.

    Considerations

    The American Society for Testing and Materials recommends the use of continuous luminescent markings on floors and walls leading to exits to increase the probability of escape.

    Features

    Fire emergency exit lights are standardized in design with 6-inch high letters with 3/4 inch stroke. Green or red letters are used for the best visibility in low or obscured light conditions. Signs not directly above an exit door must have an arrow pointing to the nearest exit to expedite escape.
