Pallet - (48) 5 Gallon Pails- Free Shipping Low viscosity with aerial visibility PHOS-CHEK® WD881C Class A foam concentrate is specially formulated to make water more effective for firefighting. PHOS-CHEK WD881C provides the same superior foam characteristics that you expect from PHOS-CHEK WD881 but disperses well, exhibits a lower viscosity, and provides improved aerial visibility when mixed with extremely cold water. PHOS-CHEK WD881C was developed specifically for use in northern regions where nighttime freezing temperatures are common during the early spring and late fall fire season. Low viscosity at cold temperatures allows the foam concentrate to be readily mixed using eductors, proportioners, and injection devices, even at near or below freezing temperatures. The unique combination of surfactants in PHOS-CHEK WD881C 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. The foam blanket creates a barrier between the fuel and the fire, knocking down the fire faster than water alone and allows fire fighters to see the areas of application. The reduced surface tension allows the water to penetrate deep into Class A fuels rather than beading up and rolling off before it can be absorbed. Making the water more effective reduces the amount of water needed to extinguish the fire and increases fire fighter safety through quicker knockdown and reduced mop-up/overhaul requirements. Both PHOS-CHEK WD881 and WD881C are the most concentrated Class A foam products available today. Many available products contain significantly more water in the concentrate. The extra water in the concentrate means higher use rates will be required to achieve expected results. PHOS-CHEK WD881C is compatible with fresh water, sea water and long-term retardant. Foam characteristics are not affected by freeze-thaw. PHOS-CHEK WD881C foam concentrate does not contain PFAS chemicals including, but not limited to, PFOS or PFOA. Fluorinated surfactants are used in Class B foam  concentrates and are necessary to form a film on flammable liquid fires.    *Can be used any season.

First Response is the latest development of a budget conscious Class A foam concentrate that compares favorably to the performance of other economy foams such as Chemguard’s Class A foam products and Ansul Silv-ex Plus. First Response is manufactured by the makers of the well known Phos-Chek® brand fire suppression products. First Response is formulated to make water more effective for fire fighting. The unique combination of surfactants significantly reduces water’s surface tension and, when mixed with air, creates a 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, and allows fire fighters to see the areas of application. Making the water more effective reduces the amount of water needed to extinguish the fire reducing water damage and increases fire fighter safety through quicker knockdown and reduced mop-up/overhaul requirements. First Response contains NO HAZARDOUS MATERIALS, is non corrosive, non-toxic, readily biodegradable, and has no flash point. It does not contain any fluorinated surfactants such as PFOS/PFOA, which are found only in Class B foams. First Response Class A foam concentrates have been tested and qualified for use by the USDA Forest Service. First Response meets the requirements of NFPA 1150. It is effective for use in Compressed Air Foam Systems (CAFS). Use Rates: Wetting Agent: 0.2% Direct Attack: 0.6% to 1.0% Mop Up/Overhaul: 0.2% to 0.6%
