Section 50.22. Exit accessibility standards

(a) Either direct access to exits or safe and continous corridors or aisles leading directly to every exit and arranged so as to be conveniently accessible by every occupant shall be maintained and kept unobstructed on all floors of buildings.

(b) Travel distances shall be measured in the following manner:

(1) Exits shall be so arranged that the total length of travel from any point to reach an exit will not exceed 150 feet.

(2) Exits shall be so arranged that one exit is not more than 200 feet from another exit.

(3) Dead ends and occupancy areas with access to a single exit shall not exceed 75 feet measured as a radius with the center of the circle being the exit.

(4) Travel distances may be increased to the following in buildings totally protected by an automatic sprinkler system installed in accordance with NFPA-13, 1983 Edition.

(i) 200 feet from any point to an exit.

(ii) 300 feet between exits.

(iii) 100 feet for dead ends and areas with a single path of egress.

(c) Exit access corridor means a corridor which is separated from all other rooms or spaces by full height partitions (floor to ceiling). Exit access corridors shall lead directly to exits. This definition is not intended to restrict the use of open plan floor arrangements. It is intended to provide protected exit access where floor areas are separated from each other by floor to ceiling partitions.

(d) All means of egress shall be properly illuminated, either naturally or artificially, during all periods of occupancy.

(e) All exits shall be marked by a readily visible sign. Access to exits shall be marked by readily visible signs indicating the direction of travel where the exit or way to reach it is not immediately visible to the occupants.

(f) Every exit sign shall have ‘‘EXIT’’ printed in plainly legible letters not less than 6 inches high with the principal strokes of letters not less than 3/4 inch wide.
