Even with high velocity water, it can still become polluted, even if the levels are indeed lower. In using water as a main source of fire fighting, it is clear that there will always be some level of toxicity in the water that is utilized in the process of stopping these fires. Ultimately, the best method of lessening fire-water is lessening fires.
APW extinguishers are commonly converted into makeshift CAFS extinguishers by drilling two 1.6–3.2 mm (1 ⁄ 16 – 1 ⁄ 8 in) holes in the pickup tube. The unit is then filled with 5.7 litres (1.5 US gal) of water and Class A foam, aqueous film forming foam (AFFF), film-forming fluoroprotein (FFFP) or commercial detergent is added to the water in a 1% ratio for class A fires and a 3–6% ...
Using water is one common method to extinguish a fire. Water extinguishes a fire by cooling, which removes heat because of water’s ability to absorb massive amounts of heat as it converts to water vapor. Without heat, the fuel cannot keep the oxidizer from reducing the fuel in order to sustain the fire. Water also extinguishes a fire by ...
He invented fire-fighting foam, which was successfully tested in experiments in 1902 and 1903. [1] In 1904 Loran patented his invention, and developed the first foam extinguisher the same year. [8] The original foam was a mixture of two powders and water produced in a foam generator.

Concerns have been raised that Phos-Chek harms fish and aquatic life; and that it causes long-term effects on soils, insects, and microbiology. [13] A group based in Oregon called Forest Service Employees for Environmental Ethics sued the U.S. Forest Service, claiming the service violated the Clean Water Act by spraying Phos-Chek without assessing the product's harmful effects on waterways.
Fire retardants are available as powder, to be mixed with water, as fire-fighting foams and fire-retardant gels. Fire retardants are also available as coatings or sprays to be applied to an object. [3] Fire retardants are commonly used in fire fighting, where they may be applied aerially or from the ground.
