NFPA Evacuation Map Requirements

NFPA 101 requires that means of egress be clearly identified and accessible to all building occupants. Evacuation maps must show primary and secondary exit routes, exit discharge locations, emergency lighting areas, fire equipment locations, areas of refuge, and assembly points. Maps should also reflect travel distance requirements and exit capacity calculations specific to your occupancy type as defined in Chapters 10-42.

While NFPA 101 doesn't use the specific word "map," it requires that means of egress be identified and that occupants can readily locate exits. Posted evacuation diagrams are the standard method for meeting these requirements. Section 7.1.10 requires emergency evacuation diagrams in certain occupancies, and fire marshals universally expect to see posted evacuation routes during inspections.

OSHA (29 CFR 1910.38) is federal law focused on employee workplace safety, while NFPA 101 is a model code adopted by states focusing on all building occupants. NFPA provides more specific requirements for travel distances, exit capacity calculations, and occupancy-specific provisions. Most facilities must comply with both - OSHA for employees and NFPA for the building itself.

Per NFPA 101 Section 7.3, calculate exit capacity using 0.2 inches per person for level components (doors, corridors) and 0.3 inches per person for stairs. Example: 200 occupants require minimum 40 inches total exit width for doors (200 × 0.2). Minimum single door width is 32 inches clear. Your total exit capacity must accommodate your calculated occupant load.

Travel distances vary by occupancy and sprinkler status. Business occupancies allow 300 ft (sprinklered) or 200 ft (non-sprinklered). Assembly occupancies: 250 ft (sprinklered) or 200 ft (non-sprinklered). Healthcare: 200 ft (sprinklered). High-hazard occupancies: 75 ft maximum. Always verify your specific occupancy classification in NFPA 101 Chapters 10-42.

NFPA 101 organizes requirements by occupancy type in Chapters 10-42. Assembly (12-13), Educational (14-15), Healthcare (18-19), Residential (26-31), Mercantile/Retail (36-37), Business/Office (38-39), Industrial (40), and Storage (42). Mixed-use buildings must comply with the most restrictive requirements from all applicable chapters. Your local AHJ determines final classification.

NFPA 101 requires that egress information remain current. Update your evacuation maps immediately after any layout changes, renovations, or equipment relocations. Best practice is a quarterly review walk-through comparing maps to actual conditions. Many jurisdictions require annual re-certification. Maps must reflect the current adopted edition of NFPA 101 in your jurisdiction.

Yes. NFPA 101 Section 11.8 defines high-rise buildings (typically over 75 feet) and requires additional provisions: voice/alarm communication systems, automatic sprinkler protection, emergency lighting with extended duration, stairwell pressurization, areas of refuge on every floor, and elevator recall. Your evacuation maps must show all these features and floor-specific evacuation procedures.
