A fire retardant is a substance that is used to slow down or stop the spread of fire or reduce its intensity. This is commonly accomplished by chemical reactions that reduce the flammability of fuels or delay their combustion. [1] [2] Fire retardants may also cool the fuel through physical action or endothermic chemical reactions.
The phosphate and sulfate salts act as fire retardants and prevent combustion of cellulosic materials. Phosphate can also act as a fertilizer once the fire danger has passed. Guar gum and clay are thickening agents to prevent dispersal of the retardant after it is dropped from the plane. Other ingredients include corrosion inhibitors and flow ...
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.
What is the fire retardant made of? The vibrant red fire retardant is known as Phos-Chek and has been used by firefighters battling wildland blazes for over 50 years, according to its manufacturer ...
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.
The discovery of high levels of heavy metals in a popular fire retardant has added to long-running concerns from environmentalists. ... My grandma’s 3-ingredient breakfast is so simple, but so good.
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 components of long-term fire retardants are mainly salts – typically agricultural fertilizers – that "alter the way the fire burns, decreases the fire intensity, and slows the advance of ...
