Intent | Intent 1: To limit the probability that certain service equipment
that penetrates fire-rated assemblies will contribute to the growth and spread
of fire within the assemblies, which could lead to the structural failure
and collapse of the assemblies, which could lead to harm to persons.
Intent 2: To limit the probability that certain service equipment
that penetrates fire-rated assemblies that also form a fire separation will
contribute to the growth and spread of fire within or through the assemblies,
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,
which could lead to harm to persons in the other compartment. |
