OS1 Fire Safety



Intent 1:

To exempt the upper and lower levels of a multi-level dwelling unit from the application of Sentence relating to egress doorways from each storey, on the basis that the travel path [stairway] to a public access to exit is separated from the rest of the dwelling unit and is not shared with egress from another level.

This [the separation] is to limit the probability that fire will spread from other storeys in the dwelling unit to the stairway, which could lead to:

  • harm to persons using the stairway, or
  • the stairway becoming untenable, which could lead to delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons.
