Abstract

Where a storey or part of a building has multiple escape routes available, one may be over a flat roof that complies with all of the following.
a. It should be part of the same building from which escape is being made.
b. The route across the roof should lead to a storey exit or external escape route.
c. The part of the roof (including its supporting structure) forming the escape route, and any opening within 3m of the escape route, should be of fire resisting construction (minimum REI 30).
d. The route should be clearly defined and guarded by walls and/or protective barriers to protect against falling.
