Height and Width Requirements
- An exit route must meet minimum height and width requirements.
- The ceiling of an exit route should be at least seven feet six inches (2.3 m) high. Any projection from the ceiling must not reach a point less than six feet eight inches (2.0 m) from the floor.
Exit doors and exit routes must meet height and width requirements.
- According to OSHA, an exit access should be at least 28 inches (71.1 cm) wide at all points. The ADA recommends 32-48 inches, and NFPA 101 , Life Safety Code, requires emergency exits to be at least 36 inches wide for new construction to accommodate those who use wheel chairs. The width may remain at 28 inches for existing buildings.
- Where there is only one exit access leading to an exit or exit discharge, the width of the exit and exit discharge should be at least equal to the width of the exit access.
- The width of an exit route should be sufficient to accommodate the maximum permitted occupant load of each floor served by the exit route.
