Firefighting foam is a foam used for fire suppression. Its role is to cool the fire and to coat the fuel, preventing its contact with oxygen, thus achieving suppression of the combustion. Firefighting foam was invented by the Moldovan engineer and chemist Aleksandr Loran in 1902. [1] The surfactants used must produce foam in concentrations of ...
In the spring of 1994, a compressed air foam demonstration vehicle manufactured by W.S. Darley & Co., was driven from coast to coast in North America by Troy Carothers. The purpose was to spread the word about CAFS and display this relatively new technology to United States and Canadian firefighting services. Many years earlier Darley Co ...
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.
Washington state – which has a sweeping PFAS ban in effect that includes firefighting foam, food packaging and cosmetics – is considering adding turnout gear and other items to the list.
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.
In such cases, it is necessary to asphyxiate the fire. This can be done in a variety of ways. Chemical products which react with the fuel can be used to stop the combustion. A layer of water-based fire retardant foam can be applied by the fire hose in order to separate the oxygen in the air from the fuel.
Fire extinguishers are one of the most common manual fire suppression devices and are required in all commercial buildings and vehicles. [2] Fire extinguishers can be used with little to no training and are meant for small incipient stage fires. The most common extinguisher is the ABC extinguisher and are found in most offices and homes.
June 2001 According to a June 2007 article in the Industrial Fire Journal (IFJ), the Firefighting Foam Coalition (FFC) was created by "[m]anufacturers of firefighting foams and the fluorosurfactants they contain" as a "focal point" for co-operation with "several environmental authorities" regarding "potential environmental impacts of its products."
