OS1 Fire Safety

Attribution

Intent

Intent 1:

To exempt corridor separations from the application of Sentence 3.3.2.6.(1) by waiving the requirement for a fire-resistance rating on the basis that the floor area is sprinklered throughout.

This is to limit the probability that a fire will not be controlled or suppressed, which could lead to the spread of fire into the corridor, or from the corridor to another part of the building, which could lead to:

  • delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons, and
  • fire emergency response operations being delayed or ineffective, which could lead to:
    • delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons, including emergency responders, and
    • the spread of fire to other parts of the building, which could lead to harm to persons.
