when exiting by ramps or horizontally. When both horizontal and stair exits are used, the total width of
exits shall be determined by using both figures as applicable. No exit shall be less than 1.10 meters in
width. Exits shall be located at a reasonable distance apart. When only two exits are provided, they
shall be spaced not less that one-fifth of the perimeter apart.
(9) Securing of Chairs

Each safe dispersal area shall have at least two exits. If more than 6000 persons are to be
accommodated within such an area, there shall be a minimum of three exits, and for more than 9000
persons there shall be a minimum of four exits. The aggregate clear width of exits from a safe dispersal
area shall be determined on the basis of not less than one exit unit of 600 millimeters for each 500
person to be accommodated and no exit shall be less than 1.10 meters in width, a reasonable distance
apart but shall be spaced not less than one-fifth of the perimeter of the area apart from each other.
(o) Special Hazards

storey, shall be set at least 100 millimeters above the roof. Curbs on which the skylights rest shall be
constructed of incombustible materials except for Types I or II Construction.
(b) Spacing between supports in one direction for flat wired glass in skylights shall not exceed
625 millimeters. Corrugated wired glass may have supports 1.50 meters apart in the direction of the
corrugation. All glass in skylights shall be wired glass: Except, that skylights over vertical shafts
extending through two or more storeys shall be glazed with plain glass as specified in this Code:
