Functional Statement:
F03
To retard the effects of fire on areas beyond its point of origin.
F02
To limit the severity and effects of fire or explosions.
F04
To retard failure or collapse due to the effects of fire.
Objective:
OS1.2, OS1.3
APPLICATION:
Combustible drain, waste and vent piping in any part of a system that penetrates:
- a fire separation required to have a fire-resistance rating, or
- a membrane that forms part of an assembly required to have a fire-resistance rating.
This applies to buildings described in Sentence
1.3.3.2.(1) of Division A.
INTENT:
To limit the probability that certain combustible piping
that penetrates fire-rated assemblies will contribute to the growth and spread
of fire within the assemblies, which could lead to a structural failure and
collapse of the assemblies, which could lead to harm to persons in the building.
To limit the probability that combustible piping that penetrates
fire-rated fire separations will contribute to the growth and spread of fire
within the fire separation, which could lead to a loss of integrity of the
fire separation, 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.
