[according to whom?] It is administered, trademarked, copyrighted, and published by the National Fire Protection Association and, like many NFPA documents, is systematically revised on a three-year cycle.

The Life Safety Code (NFPA 101) [5] and Section 803.1 of the International Building Code limit finishes for interior walls and ceilings to materials in three classes (A, B, or C, with A being the lowest flame spread and C being the highest) and gives greater restrictions for certain rooms:

It provides a method of escape in the event of a fire or other emergency that makes the stairwells inside a building inaccessible. Fire escapes are most often found on multiple ...
The Life Safety Code requires that the pressure differential across the barrier not be so great as to prevent the door from opening with a force of 30 lbf (133 N) at the door knob or handle. These 'pressurization' problems are, of course, non-existent with naturally ventilated smokeproof enclosures.
A firewall installed between substation transformers. Compartmentalization in structures, such as land-based buildings, traffic tunnels, ships, aerospace vehicles, or submarines, is an objective of passive fire protection, in which a structure is divided into fire compartments, which may contain single or multiple rooms, for the purpose of limiting the spread of fire, smoke and flue gases, in ...
