compartments should allow 2438 mm clearance for maintenance of
the exhaust system and smoke generation equipment. An equipment
space over the burner room may also be required. The ceiling
height in the egress chamber should be 2438 mm minimum.

associated with the egress chamber should be quick-acting
watertight doors. Other doors should be hollow metal. A 1829
mm wide by 2134 mm high door should be located in the staging
area to accommodate large equipment on hand trucks. The door
should have ramp access. No forklift trucks should be used.
