Intent

Intent 1:

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.

Intent 2:

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.
