§ 27-533 Travel distance.
AC § 27-533
At least one exit opening shall be available from every attached seat or standee space in an assembly space, or from the most remote point in the space when movable seats are provided or, when no seats are provided, within the primary travel distance limitation listed in table 8-1. In addition, an alternate exit opening shall be available from every attached seat or standee space, or from the most remote point when attached seats are not provided within the secondary travel distance limitation listed in table 8-1. Such alternate exit openings may serve to satisfy the requirements for primary travel distance for other seats or locations. Exit openings satisfying the primary and secondary travel distance requirements for any one seat or location shall be separated from each other by a distance of at least twenty-five feet.
(a)Travel distance shall be the measured distance along centerlines of paths of travel to the centerline of the exit opening, as adjusted by penalties for multi-directional or stepped travel as provided below.
(1)No path of travel shall be permitted through rows of seating other than the first leg of travel from a seat to an aisle.
(2)The first thirty-five feet of a primary path of travel and a secondary path of travel may be common to each other except that this distance may be increased to fifty feet in F-2 places of assembly.
(3)Not more than three changes in direction of travel shall be permitted in the path of travel to an exit opening. A change in direction shall be deemed to occur when it is necessary to change direction by a forty-five degrees or greater angle, measured from the preceding line of travel, except that it shall not be considered as a change in direction when it is necessary in an aisle or cross aisle to travel in another direction not more than seven feet.
(4)Travel distance shall be the sum of the distances of all segments of travel to the exit, computed as follows: Segment Length First leg of travel Measured distanceSecond leg of travel after first change in direction Measured distanceThird leg of travel after second change in direction 1.25 times measured distanceFourth leg of travel after third change in direction 1.40 times measured distanceAny leg of travel with four or more steps 1.25 times length of segment as computed above
