Foam supply systems are designed to protect which type of hazardous occupancies?

Foam supply systems are specifically designed to combat fires involving flammable liquids and some hazardous materials that are common in special hazardous occupancies. These systems use foam agents that smother flames and cool the fuel, effectively suppressing the fire and preventing re-ignition. Special hazardous occupancies include environments such as chemical manufacturing plants, flammable liquid storage facilities, and aircraft hangars, where traditional water-based firefighting methods may not be sufficient due to the nature of the materials involved.

Warehouses, residential buildings, and commercial offices typically do not handle the same level of fire load or contain the same types of hazardous materials that necessitate the use of foam systems. Standard fire suppression systems, like water sprinklers, are usually adequate for these types of structures, which do not present the same high risks associated with flammable liquids and hazardous substances found in special hazardous environments.
