9.29.2.2.(1)

Intent 1:

To limit the probability of repeated water exposure of moisture-vulnerable interior finishes, which could lead to the deterioration of interior finishes.

This is to limit the probability of:

• where interior finishes are required to protect foamed plastics, a loss of fire protection, or
• where interior finishes are installed to contribute to the required fire resistance of assemblies, a loss of fire resistance.

This is to limit the probability of the growth and spread of fire, which could lead to harm to persons.
