(c) External exit passageway (i) An external exit passageway may be used as a required exit in lieu of an internal exit passageway, provided that the external wall between the exit passageway and the rest of the floor space may have ventilation openings of non-combustible construction, fixed at or above a level 1.8m, measured from the finished floor level of the passageway to the sill level of the openings and such ventilation openings shall be located not less than 3m from any opening of an exit staircase, and (ii) An external exit passageway may not be subjected to the limitations of a maximum of two exit doors opening into the exit passageway, and (iii) An external exit passageway may be roofed over provided the depth of the roofed over portion shall not exceed 3m to avoid smoke logging, and (iv) An external exit passageway may be enclosed on the open side by only a parapet wall or solid balustrade of not more than 1m in height, and (v) Exit doors opening into an external exit passageway shall have fire resistance for at least half an hour and fitted with automatic self-closing device.

(d) Ventilation 2.2.5.12 ESCALATORS (i) Except as permitted by sub-clause (ii), all internal exit passageways shall be naturally ventilated by fixed ventilation openings in an external wall, such ventilation openings being not less than 15 per cent of the floor area of the exit passageway, and (ii) Internal exit passageways that cannot be naturally ventilated shall be mechanically ventilated to comply with the requirements in Section 2.6. (a) Escalators not fire-separated from the public floor area shall be considered as contributing to the means of escape capacity. (b) Escalators shall not account for more than 50% of the exit capacity at any one level. (c) Because of the possibilities of maintenance or malfunction, one escalator at each station shall be considered as being out of service in calculating egress requirements. The escalators chosen shall be the one having the most adverse effect upon exiting capacities. (d) The width of the escalator shall be the width of the step tread. (e) Escalators shall be provided with flat steps at landings which increase in number proportionally with the rise of the escalator as follows: Rise Number of Flat Steps Up to 6 m Not less than 2 6 – 18 m Not less than 3 Over 18 m Not less than 4 (f) Where operating in the direction of exit travel, escalators shall be permitted to be left in the operating mode during evacuation.
