9.9.3.2. (1) Each room, guest suite, podium, terrace, platform, contained open space or other area intended for occupancy
shall have egress facilities leading directly to (a)  a public thoroughfare, (b)  an approved
open space that has access to a public thoroughfare, or (c)  a corridor where it is possible to go in opposite directions to separate exits, except as otherwise permitted by this Article or Article 9.9.3.3. Dead end corridors (2) Dead end corridors shall not be longer than 6 m plus the width of the corridor, unless otherwise approved. (3) Unless otherwise approved, no area may be served by a dead end corridor where (a)  the area contains an assembly occupancy and its occupant load is greater than 20 persons, (b)  the area is intended for storage and exceeds 200 m2, or (c)  the area is intended for a use other than that described in Clauses (a) and (b) and exceeds 100 m2 in area or has an occupant load greater than 24 persons. (4) If a guest suite has access to a second exit
or if a guest suite is in a building
that is permitted to be served by a single exit
in compliance with Article 9.9.3.3., a doorway from the guest suite may open onto (a)  an exit
stairway, (b)  a fire escape, (c)  a corridor served by a single exit, or (d)  an exterior passageway served by a single exit stairway. Egress facilities (5) Each room, guest suite, podium, terrace, platform, contained open space or other area intended for occupancy shall have two egress doorways placed in such a manner that one doorway could provide egress from the room or area if the other doorway becomes inaccessible to the occupants due to a fire which might originate in the room or area where (a)  the space is intended for assembly occupancy, and (i)  the distance of travel to an egress door from any point in the space exceeds 15 m, or (ii)  the occupant load exceeds 60 persons, (b)  the space is intended for storage, and (i)  exceeds 200 m2
in area, or (ii)  the distance of travel to an egress door from any point in the space exceeds 23 m, or (c)  the space is intended for a use other than that described in Clauses (a) and (b), and (i)  exceeds 100 m2
in area, or (ii)  the occupant load exceeds 60 persons. (6) Despite Sentence (5), every room containing an assembly occupancy shall be provided with at least (a)  three independent well-separated egress doorways, where its occupant load is 600 persons or more, and (b)  four independent well-separated egress doorways where its occupant load is 1000 persons or more. (7) Where a room or floor area is divided into individual spaces for assembly occupancy, egress through an adjacent assembly occupancy
is permitted provided each space has at least one independent egress doorway in accordance with Sentence (1) and dividing walls or partitions
are not more than 1.35 m in height. (8) Dividing walls or partitions in Sentence (7) may exceed 1.35 m in height if alternative provisions are approved to provide safe egress. Egress widths (9) The aggregate width of required means of egress from a floor area or portion of a floor area shall be determined by multiplying the occupant load of the area served by (a)  6.1 mm per person, for ramps with a gradient of not more than 1 in 8, doorways, corridors and passageways, or (b)  9.2 mm per person, for ramps with a gradient of more than 1 in 8 and stairs. (10) Where two or more egress doorways are required from a floor area or portion of a floor area, a sufficient aggregate width shall be provided so that the egress capacity is not reduced by more than half if any one doorway or opening is inaccessible in an emergency. (11) Despite Sentences (9) and (10), the minimum clear width of a means of egress shall be not less than (a)  1100 mm for corridors, (b)  900 mm for stairs, and (c)  750 mm for doorways, ramps and all other areas.
