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.
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 ...

[1] Fire-retardant gels can also be slurries that are composed of a combination of water, starch, and clay. [2] Used as fire retardants, they can be used for structure protection and in direct-attack applications against wildfires. [3] [4] Fire-retardant gels are short-term fire suppressants typically applied with ground equipment. [5]
