NFPA 101 , Life Safety Code

Code red safety

In 1913, the NPFA s Committee on Safety to Life began an analysis of notable fires involving loss of life. This work led to the development of standards for stairways, fire escapes, and exit facilities that were published in 1916 (Outside Stairs for Fire Exits) and 1918 (Safeguarding Factory Workers from Fire). These standards were expanded and merged with other safety standards in 1921, and published as the Buildings Exits Code.

A deadly series of fires between 1942 and 1946 (notably the November 19, 1942 Cocoanut Grove Night Club Fire in Boston, Massachusetts, and the December 7, 1946 Winecoff Fire in Atlanta, Georgia) led to the beginning of a revision of the Building Exits Code from a tool for building contractors to a a potential model code, and several versions were published before the Committee on Safety to Life was restructured in 1963. For the 1966 version, the name was changed from the Building Exits Code to Code for Safety to Life from Fire in Buildings and Structures. After further reorganization and several versions later, the modern Life Safety Code had become the modern code which would be widely adopted in the United States as model legislature.

The portion of the NFPA 101 , Life Safety Code that applies to emergency lighting, exit signs, and means of egress is presented below (from the 2015 edition). The NFPA 101, Life Safety Code is a model code, and while some states or localities have implemented the code in full, other states or locality have implemented only certain parts and changed others. For the most accurate information on your local codes, check with your local code enforcement agency.
