Back3.1.8.6.(2)

ATTRIBUTION:

Functional Statement:

F03

To retard the effects of fire on areas beyond its point of origin.

Objective:

OS1.2

 

APPLICATION:

Maximum size of openings in an interior fire separation required to be protected with a closure where the fire compartments on both sides of the fire separation are sprinklered, in buildings described in Sentence 1.3.3.2.(1) of Division A.

INTENT:

To limit the probability that large closures--which are permitted to have a lower resistance to fire than do the fire separations--will reduce the fire-resistance rating of the fire separations, which could lead to the spread of fire from one fire compartment to another fire compartment, which could lead to harm to persons in the other fire compartment.
