High Hazard

High Hazard

High Hazard is a class of hazard wherein the amount and type of combustibles present are such that fires of large initial size may be expected. Typical high hazards include woodworking areas, warehouses with high-piled storage in excess of 4.5 m, foam plastics processing and storage which constitutes a Class A fire risk.

NOTE: Special consideration should be given to occupancies, which, because of their high-fuel load, may more correctly be allocated a higher hazard class.
