3.13.4.5. — Width of Means of Egress

(1) Except as otherwise required in this Subsection, the required width of means of egress serving platforms in a rapid transit station shall be determined based on,

(a) the required egress capacity determined in conformance with Article 3.13.4.4., and

(b) the pedestrian flow rate for the type of means of egress facility listed in Table 3.13.4.5.

(2) In calculating the required width of corridors and ramps with a grade of less than 4%, 300 mm at each sidewall shall be added to the width determined based on required egress capacity.

(3) In calculating the required width of egress routes, one escalator at each level in a rapid transit station shall be deemed to be out of service and not available for egress purposes.

(4) Except as provided in Sentence (5), the minimum width of means of egress facilities serving platforms shall be,

(a) 1 750 mm for corridors and ramps,

(b) 1 750 mm for stairs,

(d) 500 mm for fare collection gates,

(e) 600 mm nominal width for escalators, and

(f) 900 mm for a door leaf.

(5) A second means of egress as required by Sentence 3.13.4.3.(1) is permitted to be not less than 1 100 mm wide.

(6) The minimum width of platforms shall be,

(a) 3.2 m for side platforms, and
