Phos-Chek WD881 Class A Foam Concentrate

ITEM #: WD881 PHOS-CHEK

Phos-Chek WD881 Class A Foam Concentrate

The Phos-Chek WD881 Class A Foam Concentrate has been formulated to make water more effective for firefighting. The unique combination of surfactants in WD881 significantly reduces water's surface tension and, when mixed with air, creates a superior foam blanket that surrounds fuels with a thick layer of water. This creates a barrier between the fuel and the fire, knocking down the fire faster than water alone, allowing firefighters to see the areas of application. Making the water more effective reduces the amount of water needed to extinguish the fire, reduces water damage and increases fire fighter safety through quicker knockdown and reduced mop-up/overhaul requirements.

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.
