OP1 Fire Protection of the Building



Intent 1:

To override the requirement for a flame-spread rating of not more than 25 in Clause and to permit a higher flame-spread rating if an automatic fire suppression system is provided.

This is to limit the probability that a fire in the power-ventilated enclosure and exhaust duct system will spread to other parts of the building, which could lead to damage to the building.
