Sentence 3.3.1.4.(3)

Intent 1:

To exempt fire separations in public corridors from the application of Sentence 3.3.1.4.(2), which would otherwise require the fire separation to have a fire-resistance rating, on the basis that the storey is sprinklered throughout and the corridor does not serve certain occupancies.

This is to limit the probability that a fire will not be suppressed or controlled, 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 damage to the building, and
• fire emergency response operations being delayed or ineffective, which could lead to the spread of fire to other parts of the building, which could lead to damage to the building.
