NFPA 101: Life Safety Code

The Life Safety Code (NFPA 101) is a widely used consensus standard that sets requirements to protect people from fire, smoke and similar emergencies in buildings: how many exits are needed, how wide, how marked, and what alarms, sprinklers and drills must be provided. It is written by the National Fire Protection Association (NFPA) and becomes law only where a state, city or agency adopts it.

• Safety Managers
• Facility Inspectors
• Healthcare & School Staff

What the code covers

• Means of egress: the continuous, unobstructed path from any point in a building to a safe place outside, made of the exit access (the way to the exit), the exit (a protected path such as an enclosed stair) and the exit discharge (the way from the exit to the street). See Exit Routes.
• Occupancy classifications: assembly, educational, health care, detention, residential (one- and two-family, lodging and apartments), mercantile, business, industrial, storage and others. Each has its own rules on exits, sprinklers and alarms.
• Exit capacity and travel distance: how many people each door and stair can serve, the number of exits and the maximum distance to an exit, the width of corridors and the common path of travel.
• Doors, stairs and ramps: door swing, locks and hardware that allow free exit, handrails, stair width, landings and fire-rated doors. See Stairways.
• Exit signs and emergency lighting so exits can be found in smoke and during power loss.
• Fire alarm and detection systems to warn occupants, and sprinklers to control fire. See NFPA Sprinkler Standards and Fire System Impairments.
• Fire and smoke barriers, compartmentation and protection of vertical openings such as stairs and shafts.
• Interior finish and furnishings flame spread and smoke rules.
• Emergency planning and drills: fire drills in schools, hotels and other occupancies, and staff training for health care. See Emergency Action Plans.
• Special features for high-rise, health care, detention, assembly and large-capacity buildings.

How it relates to other rules

• Voluntary until adopted. NFPA 101 is a consensus code. States, cities, fire marshals and agencies (such as health care funders) adopt specific editions, often with amendments. Check the edition your authority uses.
• OSHA has its own rules for exit routes, emergency action plans and fire protection (29 CFR 1910 Subpart E and Subpart L). OSHA's rules overlap with NFPA 101 but are not the same, and OSHA may refer to NFPA codes as evidence of recognized practice. See Exit Routes and General Industry (1910).
• Building and fire codes (International Building Code and International Fire Code, or NFPA 1 and NFPA 5000) also address egress and fire protection, and may be used instead of or alongside NFPA 101. See Building Codes and International Fire Code.
• NFPA 101 applies to new and existing buildings, with separate chapters. Existing buildings often have different requirements than new ones.
• When rules differ, the stricter or the one adopted locally usually controls. Ask your fire marshal or building official.

What workers and managers can do

• Keep exits clear and unlocked from the inside during occupancy, with aisles, corridors and stairs free of storage and clutter. No chains, blocked doors or locked emergency exits. See Exit Routes.
• Make sure exit signs and emergency lights work, are visible and are tested as required.
• Keep fire doors closed and not wedged open, and don't remove self-closing devices. Don't prop open stair doors.
• Report alarm and sprinkler problems and keep sprinkler heads and fire alarm devices unobstructed. Keep storage 18 inches below sprinkler heads where required by sprinkler rules.
• Participate in fire drills and know your evacuation route and assembly point. See Evacuation Headcounts.
• Know your occupancy load limits and don't exceed posted capacity in assembly rooms.
• Plan for people who need help evacuating and communicate the plan.
• Use permits and impairment procedures when fire systems are out of service. See Fire System Impairments.

Inspections and enforcement

• Fire marshals and building officials inspect buildings for egress, alarm, sprinkler and storage violations, and can order corrections or closures. See Permits & Inspections.
• Health care facilities that receive Medicare or Medicaid money must meet life safety requirements based on NFPA 101 as adopted by the federal agency.
• Document inspection, testing and maintenance of alarms, sprinklers, lights and doors, and keep records for inspectors.
• The code is updated every few years. Check which edition applies to your building and project.

Life Safety Code checklist

• Exits, corridors and stairs are clear, unlocked from inside and well-marked
• Exit signs and emergency lighting work and are tested
• Fire doors close fully and aren't propped open
• Alarms and sprinklers are working, unobstructed and tested; impairments follow procedure
• I know which code edition my authority adopted, and drills are held
