Class A foam is used as a fire retardant in 2.5 gallon [APW] and [CAFS] extinguishers to contain incipient brush fires and grass fires by creating a fire break. Other chemical retardants are capable of rendering class A material and Class B fuels non-flammable and extinguishing class A, class B, and some class D fires.
The fireproofing of wood utilizes a fire retardant chemical that remains stable in high temperature environments. The fire retardant is applied under pressure at a wood treating plant like the preservatives described above, or applied as a surface coating. In both cases, treatment provides a physical barrier to flame spread.
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.
Homes with wood siding or cedar shakes can be treated with fire-retardant chemicals, though in California, such treatments must meet standards set by the [California State Fire Marshall] 9https ...
Microbial metabolism in products treated with TBP is known to produce 2,4,6-tribromoanisole (TBA), [9] which has a musty odor. In 2010 and 2011, Pfizer and Johnson & Johnson voluntarily recalled some products due to TBA odors from wooden pallets which were treated with TBP. [10] [11] [12] [13]
Furfurylated wood, holding the Scandinavian ecological label Swan, is today traded as an environmentally friendly product since both the wood and furfuryl alcohol are produced from renewable raw materials. [14] In recent years, attempts to make furfurylated wood as a fire resistant material, have been made. [15] [16]
San Antonio Statement on Brominated and Chlorinated Flame Retardants 2010: [51] A group of 145 prominent scientists from 22 countries signed the first-ever consensus statement documenting health hazards from flame retardant chemicals found at high levels in home furniture, electronics, insulation, and other products. This statement documents ...
Research on fire-retardant polymers was bolstered by the need for new types of synthetic polymers in World War II. The combination of a halogenated paraffin and antimony oxide was found to be successful as a fire retardant for canvas tenting. Synthesis of polymers, such as polyesters, with fire retardant monomers were also developed around this ...
