Objective

OP1 Fire Protection of the Building

Attribution

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 exit fire separations, and limit the openings to only certain penetrations, on the basis of maintaining the integrity of exits.

This is to limit the probability that:

  • fire will spread into an exit, which could lead to delays or ineffectiveness in fire emergency response operations, which could lead to the further spread of fire, which could lead to damage to the building, and
  • fire will spread from one floor area to another floor area by means of an exit, which could lead to damage to the building.
