Section 7.7.1/Discharge from Exits
NFPA 101 Section 7.7 covers exit discharge requirements establishing that exits must lead to a public way or through a protected discharge path.
Exits must terminate directly at a public way or at an exterior exit discharge that provides a safe path to a public way. The exit discharge must be at least as wide as the exit it serves. Not more than 50 percent of the required number of exits may discharge through the level of exit discharge (typically the ground floor interior) before reaching the exterior, and only when the path is protected by automatic sprinklers, enclosed by fire-rated construction, and leads directly to an exterior exit door.
Why this section exists
The exit discharge is the final segment of the egress path. An exit stairway that ends in a basement instead of at grade, or that discharges into an unprotected lobby, defeats the purpose of the enclosed stairway. Occupants who have navigated through smoke-filled corridors and down enclosed stairways must be able to reach the exterior without re-entering a fire-exposed area. The 50 percent limit on interior discharge ensures that at least half the exits always lead directly outside.
What plan reviewers look for
Plan reviewers trace each exit from the stairway or exit passageway to the point where it reaches the exterior. They verify that each exit leads to a public way (street, alley, or open area) and that the path is clear of obstructions. If any exits discharge through the interior at the level of exit discharge, they verify the 50 percent limit, the sprinkler protection, the fire-rated enclosure, and the direct path to an exterior door.
