Dangerous industrial fires are often Class-B, that is, they involve flammable or combustible liquids which can result in fast spreading and explosive reactions. Using water for Class-B fires is a bad mistake, since it fails to suppress the fire as most fuels and flammable liquids are not only bouyant and ride atop water, but also release flammable gases and fumes. In fact, water will only help to rapidly spread Class-B fires. That's why Class-B Foams are employed to combat many industrial fires, since these foams are specifically designed to coat and suppress flammable liquids. Class-A Foams (designed for wildfire suppression) should never be used on a Class-B Fire since the results are unpredictable and often counter-productive. Action Response Team operates Class-B Foam suppression in coordination with our Confined Space Division, and when we are already on-site we have the tremendous benefit of attacking the fire while it is still in its early stages, well before a fire department can be deployed (Assuming a fire dpt. has Class-B Foam capability), therefore keeping what starts as a small fire from becoming something worse.
