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 public corridor, or from
the public corridor into a suite, 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.
