WD881 is highly effective for fighting Class A fires when mixed with water at use rates of 0.1% to 1.0%. It has proven effectiveness in many applications including Compressed Air Foam Systems (CAFS), structural firefighting, forest fire suppression and prescribed burning, mine fires, industrial Class A fires, and for extinguishing hydrocarbon spill fires.
Phos-Chek WD881 is the most concentrated Class A foam product available today. Other products contain significantly more water in the concentrate. This extra water means higher use rates will be required to achieve expected results.
WD881 does not contain fluorinated surfactants such as PFOS/PFOA. Fluorinated surfactants are used in Class B foam concentrates and are necessary to form a film on flammable liquid fires.
Class B foams should not be used on Class A fires. Never mix Class A and Class B foam concentrates.
