Intent 1:
To exempt public corridor separations from the application
of Sentence 9.10.9.15.(1) by waiving the requirement for a fire
separation if certain conditions are met [i.e. the floor area is sprinklered
throughout, the sprinkler system meets certain operational requirements,
and the corridor has a minimum width].
This [the
sprinklering and the minimum corridor width] is to limit the probability:
- that a fire will not be controlled or suppressed [sprinklering],
which could lead to the spread of fire into the public corridor, or
from the public corridor into a suite, and
- of overcrowding in corridors during a fire situation
[minimum corridor width].
This is to limit the probability of:
- delays in the evacuation or movement of persons to a
safe place, or
- delays or ineffectiveness in fire emergency response
operations, which could lead to
- delays in the evacuation or movement of persons to a
safe place, or
- the spread of fire to other parts of the building.
This is to limit the probability of harm to persons.
