9.10.9.15.(3)

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] is to limit the probability that a fire will not be controlled or suppressed, which could lead to the spread of fire into the public corridor, or from the public corridor into a suite, which could lead to:

• damage to the building, or
• delays or ineffectiveness in fire emergency response operations, which could lead to the spread of fire to other parts of the building, which could lead to damage to the building.

This [the minimum corridor width] is to limit the probability of overcrowding in corridors during a fire situation, which could lead to delays or ineffectiveness in emergency response operations, which could lead to the spread of fire, which could lead to damage to the building.
