Fomtec Enviro Class A is a novel blend of high activity hydrocarbon surfactants, selected for their environmental profile, solvents and stabilizers, for use on class A fuel fires and smaller class B fires. Enviro Class A does not contain any fluorinated surfactants or polymers (PFAS) or other organohalogens. Enviro Class A does not contain any hazardous substances and does not require any special labelling when transported.
Enviro Class A provides excellent extinguishments of class A fires by providing deep penetration of the water into the burning material and an insulating foam blanket. Even at low concentrations it provides a strong wetting effect. Enviro Class A is also suited for smaller class B fires. Enviro Class A can be used with both aspirating and non-aspirating discharge devices. It is compatible with all dry chemical powders.
