Intent | Intent 1: To supersede the requirements of Subsections 3.1.8., 3.1.9. and 3.2.8., which would otherwise permit openings
in fire separations of vertical service space enclosures, and limit the openings
to only certain penetrations, on the basis of maintaining the integrity of
the enclosures. Intent 2: To limit the probability that fire will spread from one
storey to another storey by means of a vertical service space, which could
lead to damage to the building. |
