Class A Foam

NAFFCO Class A Foam is an non-corrosive, non-toxic, biodegradable Class A fire fighting foam concentrate. When mixed with water in the correct proportion, it changes the properties of water; it reduces the surface tension of the water, and produces foam which allows the water to cling to vertical or horizontal surfaces without run off. This allows the water to absorb more heat and provides greater penetration into Class A fuels.
