- Exits: Two exits shall be required for stories with less than 500 occupants. Three exits shall be required for
stories with 501 to 1,000 occupants. Four exits shall be required for stories with more than 1,000 occupants.
Two means of egress are also required from all mezzanines with an occupant load greater than 50 or with exit
travel distance greater than 75 feet.
- A single exit is permitted in the story at the level of exit discharge when the occupant load of the story does not exceed 50 and the exit access travel distance does not exceed 75 feet.
- Existing fire escapes shall be accepted as providing one of the required means of egress unless
judged to be dangerous for use under emergency exiting conditions. For use of fire escapes, access
shall be through a door except when serving an occupant load of 10 or fewer. All occupants shall have
unobstructed access to fire escapes without having to pass through a room subject to locking.
- When more than one exit is required and there is not sufficient space for an exterior stair within the lot line, a new fire escape shall be accepted as providing one of the required means of egress. Newly-installed fire escapes shall comply with FTO-3.
- Ladders shall be prohibited on fire escapes used as a required means of egress. (Plan review--Building, Fire. Inspection--Building)
- Egress Doorways: A minimum of two egress doorways shall be required for all rooms and spaces with an
occupant load greater than 50 or in which the travel distance exceeds 75 feet. All egress doors serving an
occupant load greater than 50 shall swing in the direction of exit travel.
- Exception: Storage rooms with a maximum occupant load of 10 shall not be required to have two egress doorways.
- All required exit doors equipped with latching devices in buildings or spaces with an occupant load greater than 100 shall be equipped with approved panic hardware. (Plan review--Building, Fire. Inspection--Building)
- Capacity of Means of Egress: The capacity of the means of egress in each work area shall be determined in accordance with N.J.A.C. 5:23-6.11(b). Additionally, for buildings with an occupant load of 100 or more, a main entrance capable of serving as the main exit with an egress capacity for at least one-half the total occupant load is required. The remaining exits shall be capable of providing one-half of the total required exit capacity. This provision shall not apply in buildings with multiple main entrances. (Plan review--Building, Fire. Inspection--Building)
- Dead End Corridors: Existing dead end corridors shall not exceed 35 feet in length. Exceptions are allowed as follows:
- Dead end corridors may be up to 50 feet in length in a building with an automatic alarm system installed in conformance with the building subcode in effect at the time of its installation.
- Dead end corridors may be up to 70 feet in length in a building with an automatic sprinkler system installed in conformance with the building code in effect at the time of its installation. (Plan review--Building, Fire. Inspection--Building)
- Means of Egress Lighting: Artificial lighting with an intensity of not less than one foot candle at floor level
shall be required during all times that the conditions of occupancy of the building require that the exits be
available. Lighting shall also be required to illuminate the exit discharge. In all buildings, rooms or spaces
required to have more than one exit or exit access, means of egress lighting shall be connected to an
emergency electrical system conforming to NFPA 70 (NEC) except that continued illumination shall be required
to be provided for not less than one hour in the case of primary power loss.
- In buildings used for motion pictures or other projections by means of directed light, the illumination of aisles may be reduced during periods of projection to not less than 0.2 foot candle. The switch requirements and location(s) for controlling egress lighting connected to the emergency electrical system shall be in conformance with the NFPA 70 (NEC). (Plan review--Building, Fire, Electric. Inspection--Building)
- Illuminated Exit Signs: Illuminated exit signs shall be provided for all required means of egress in all
buildings, rooms or spaces required to have more than one exit or exit access. Exit signs shall be visible from
the exit access and supplemented by directional signs when necessary. (Exception: Approved main exterior
doors that are clearly identified as exits are not required to have exit signs.) Exit signs shall meet the following
- Red or green letters at least six inches high; minimum width of each stroke 3/4 inch on a white background or in other approved distinguishable colors. Arrows, if provided, shall be such that the direction cannot readily be changed. The word "Exit" shall be clearly discernible when the sign is not energized.
- Exit signs shall be illuminated at all times when the building is occupied by a source providing at least five foot candles at the illuminated surface or shall be approved self-luminous signs which provide evenly illuminated letters with a minimum luminance of 0.06 foot lamberts. Exit signs shall be connected to an emergency electrical system conforming to NFPA 70 (NEC) except that continued illumination shall be required to be provided for not less than one hour in the case of primary power loss. No emergency power shall be required for approved self-luminous signs. (Plan review--Building, Fire. Inspection--Building)
- Handrails: Every required exit stairway having three or more risers and not provided with handrails or in which the existing handrails are in danger of collapsing when used under emergency exiting conditions, shall be provided with handrails for the full length of the run of steps on at least one side. All exit stairways more than 66 inches wide shall have handrails on both sides unless the full width of the stairway is not needed to accommodate the design occupancy. (Plan review--Building, Fire. Inspection--Building)
- Guards: Every open portion of a stair, landing or balcony which is more than 30 inches above the floor or grade below and is not provided with guards or those in which the existing guards are in danger of collapsing when used under emergency exiting conditions, shall be provided with guards. (Plan review--Building, Fire. Inspection--Building)
- Vertical Opening Protection: Vertical opening protection for interior stairways and other vertical openings shall be provided as follows:
- For vertical openings connecting more than six floor levels, approved assemblies having a fire resistance rating of not less than two hours with approved opening protectives shall be required.
- For vertical openings connecting four to six floor levels, approved assemblies having a fire resistance rating of not less than one hour with approved opening protectives shall be required.
- For vertical openings not exceeding three stories, a minimum 30-minute UFC fire barrier shall be
required. Exceptions are as follows:
- When connecting the main floor and mezzanines; or
- When all of the following conditions are met:
- The communicating area has a low hazard occupancy or has a moderate hazard occupancy which is protected throughout by an automatic sprinkler system;
- The lowest or next to the lowest level is a street floor;
- The entire area is open and unobstructed in a manner such that it may be assumed that a fire in any part of the interconnected spaces will be readily obvious to all of the occupants;
- Exit capacity is sufficient to provide egress simultaneously for all the occupants of all levels by considering all areas to be a single floor area for the determination of required exit capacity; and
- Each floor level, considered separately, has at least one-half of its individual required exit capacity provided by an exit or exits leading directly out of that level without having to traverse another communicating floor level or be exposed to the smoke or fire spreading from another communicating floor level.
