When contacted by spatter of molten metal during a welding process the material protects the surrounding areas by maintaining the structural integrity of the blanket. [2] Many modern welding blankets are made of flame retardant fiberglass and can stand working temperatures ranging from 300 to 2,500 degrees Fahrenheit.

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.
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 .
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. These solvents extract the water contained in the foam, breaking down the foam blanket.
The retardant is applied ahead of wildfires to homes [5] [6] and vegetation by ground crews and aerial firefighting units, either fixed-wing or rotary-wing aircraft. [7] 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
