Intent | Intent 1: To limit the probability that coverings and linings will
have inappropriately high flame-spread and smoke-development properties, which
could lead to the development of an inappropriate amount of smoke and the
spread of fire across the exposed surfaces of the material, which could lead
to the spread of fire and smoke to other parts of the building by means of
the air duct systems, which could lead to harm to persons. |
