[1] [2] Fire retardants may also cool the fuel through physical action or endothermic chemical reactions. Fire retardants are available as powder, to be mixed with water, as fire-fighting foams and fire-retardant gels. Fire retardants are commonly used in fire fighting, where they may be applied aerially or from the ground.
As of 2022, Phos-Chek LC-95A is the most used fire retardant in the world. [8] A Phos-Chek tank trailer at Ramona Airport. Phos-Chek is produced in several colors, including red, uncolored, and fugitive. The colored retardant gradually fades to an earth-tone when exposed to sunlight. [9] The red color aids aircrews in targeting drops of ...
Flame retardants manufactured for use in consumer products have been released into environments around the world. The flame retardant industry has developed a voluntary initiative to reduce emissions to the environment (VECAP) [87] by promoting best practices during the manufacturing process. Communities near electronics factories and disposal ...
The red color of the fire retardant is caused by the chemical component iron oxide, commonly known as rust. ... The long-term fire retardant, often used to steer wildfires and protect critical ...
This provides dramatic fire knockdown, an important factor in crash rescue firefighting. In the early 1970s, National Foam, Inc. invented alcohol-resistant AFFF technology. AR-AFFF is a synthetic foam developed for both hydrocarbon and polar-solvent materials. Polar solvents are combustible liquids that destroy conventional fire-fighting foam.
Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat. An example of a fire-resistant material is one which is used in bunker gear worn by firefighters to protect them from the flames of a burning building.
The discovery of high levels of heavy metals in a popular fire retardant has added to long-running concerns from environmentalists. Wildfire retardant is laden with toxic metals, USC study finds ...
Until the late 1970s, TDCPP was used as a flame retardant in children’s pajamas in compliance with the U.S. Flammable Fabrics Act of 1953. This use was discontinued after children wearing fabrics treated with a very similar compound, tris(2,3-dibromopropyl) phosphate, were found to have mutagenic byproducts in their urine.
