The publication Life Safety Code, known as NFPA 101, is a consensus standard widely adopted in the United States.

[4] This is partly a historical consequence of the installation of heat and smoke vents following the August 1953 General Motors, Livonia, MI major fire in a nonsprinklered manufacturing facility which effectively stopped the production ...
First published in 2002, the code set named the Comprehensive Consensus Codes, or C3, includes the NFPA 5000 building code as its centerpiece and several companion codes such as the National Electrical Code, NFPA 101 Life Safety Code, Uniform Plumbing Code, Uniform Mechanical Code, and NFPA 1.
