Which NFPA standard provides guidelines for emergency lighting systems?

The NFPA standard that provides guidelines for emergency lighting systems is NFPA 101, also known as the Life Safety Code. This standard specifically addresses means of egress, including the necessary requirements for emergency lighting to ensure safe evacuation during power failures or other emergencies. It dictates the minimum levels of illumination needed in paths of egress, as well as the performance criteria for emergency lighting systems to ensure they function correctly when needed.

In addition, NFPA 101 emphasizes the importance of maintaining adequate visibility in evacuation routes and assembly areas, thus facilitating a safe exit for occupants. It integrates the requirements for emergency lighting within a broader framework of life safety as it pertains to building design, occupancy, and operation.

Other standards such as NFPA 72, which deals primarily with fire alarm and signaling systems; NFPA 5000, focusing on building construction and safety; and NFPA 13, which outlines the installation of sprinkler systems, do not specifically provide the guidelines for emergency lighting systems. Instead, they address different aspects of fire safety and prevention in buildings.
