Currently used in every U.S. state and adopted statewide in 43 states, NFPA 101: Life Safety Code, addresses minimum building design, construction, operation, and maintenance requirements necessary to protect building occupants from danger caused by fire, smoke, and toxic fumes. The Life Safety Code is truly the genesis of nearly all means‐of‐egress and life safety criteria codes used in the United States.

NFPA 101 is the most comprehensive code addressing safety to life from fire and similar emergencies in both new and existing buildings. The Life Safety Code can be used in conjunction with a building code or alone in jurisdictions that do not have a building code in place.

Revisions to the 2024 Edition include:

• Updated emergency action plan requirements to address security features, allowance for other exits associated with horizontal exits, revised listing and installation requirements for two-way communication systems in areas of refuge.
• New requirements for inflatable amusement devices, modular rooms, and sleep pods.
• Smokeproof enclosure exemption for sprinklered high-rise buildings.
• Additional carbon monoxide detection requirements for various new and existing facilities
• Mandatory automatic sprinkler system requirements for all new parking structures.
