Sentence 3.1.9.1.(3)

Intent 1:

To limit the probability that penetrations of a fire separation will not be sealed, which could lead to a failure of the integrity of the fire separations, which could lead to the spread of fire and smoke from one fire compartment to another fire compartment, which could lead to harm to persons in the other fire compartment.

Intent 2:

To exempt penetrations of a fire separation from the application of Sentence 3.1.9.1.(1), on the basis that a higher level of performance with respect to sealing is required for these fire separations.
