NFPA Fire Code

Fire safety signage and emergency egress marking.

NFPA standards — including NFPA 1 (Fire Code), NFPA 101 (Life Safety Code) and NFPA 170 (Standard for Fire Safety and Emergency Symbols) — define how fire and emergency signage must look, where it must be placed and how visible it must be in smoke or power failure.

Where this standard applies

  • High-rise buildings and large commercial complexes
  • Hospitals, hotels and educational institutions
  • Any facility certifying to NFPA / NBC fire safety

Key requirements

  1. 1Exit signs must be internally or externally illuminated and remain visible for at least 90 minutes of power failure (NFPA 101).
  2. 2Use NFPA 170 standard pictograms for fire alarm pull stations, extinguishers, hose reels and hydrants.
  3. 3Mount low-level exit path markings where smoke accumulation is expected (assembly, high-rise, healthcare).
  4. 4Post floor plans with 'You Are Here' egress diagrams on every floor of buildings under NFPA 101 occupancies.
