CLASS A FOAM SUPPRESSANTS

Foams contain foaming and wetting agents like those found in dishwashing detergents and other cleaners. Foams depend on the water they contain to suppress fire. Once the water has evaporated the foam is not effective. This property makes them most effective for direct attack and mop up. Only Class A foams are used on wildland fires.

Class A foam suppressants depend on the water they contain to suppress the fire.

Refer to the Class A Foam Fact Sheet for an in depth description of Class A foam suppressants.

Forest Service Specification FS 5100-307b provides the specific requirements for qualifying class A foam suppressants.

WFCS tests wildland fire chemicals thoroughly to ensure both human and ecological health and safety. We integrate risk assessments and environmental consultations into our testing and approval processes. Refer to the following links for more information about using long-term retardants:

If your company is interested in submitting long-term fire retardants for evaluation, check out our submit a product section.

WFCS must first evaluate and approve long-term fire retardants before they can be used on Federal lands. The process for fully evaluating products can take 18 to 24 months. We list these products on our QPL once we approve them.
