Chemistry of Fire Retardancy SUSAN L. LEVAN U.S. Department of Agriculture,Forest Service, Forest Products Laboratory, Madison, WI Fire retardancy of wood involves a complex series of simultaneous chemical reactions, the products of which take part in subsequent reactions.

Most fire retardants used for wood increase the dehydration File Size: KB. A fire retardant is a substance that is used to slow 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. Fire retardants may also cool the fuel through physical action or endothermic chemical reactions. Fire retardants are available as powder, to be mixed with.

Fire retardants work three ways: removing heat, coating the surface (so the fuel can't find oxygen), or by diluting the air near the fire.

Water is a great fire retardant because it does all three. The questions above sound like they are asking the same thing, but the asker of the first probably wants to know if the product is fire retardant treated (FR or FRT) to a Class A Flame Spread Index.

Flame retardant additives offer a potential short-term solution for reducing the combustibility of composites, and hence the reduction of the associated hazards. A brief review of fire modelling was performed to identify suitable mathematical expressions with which the results of the experimental flame retardant investigation were analysed.
