Class A Foam Uses. Class b foams should not be used on class a fires. The purpose of class “a” concentrate is to allow water to create a foam blanket on a burning class “a” fuel and keep it there where plain water beads up and runs off. For any wildland or structural brigade that has to bring its water to the scene, and has to establish water tanker shuttles, using class a foam can easily increase operational efficiency of fighting the fire. Class a foam concentrate is used for fire fighting wildland and structural fires which consist of ordinary combustible materials, such as paper, cloth, wood, coal and rubber.

Class b foams should not be used on class a fires. The reason is that, class a foam, when properly deployed, allows the fire to be extinguished more quickly and with far less water than would be required if foam was not used. Also, foam, dry powder, and wet chemical fire extinguishers are convenient for this fire class. Class a foams are often intended for use at very low concentration of 0,1 to 1%, and are formulated using environmentally favourable raw materials. • use for class b fires. However, by adding a small amount of class “a” foam concentrate to the water, it becomes 3 to 5 times more efficient.
Wd881 class a foam enhances a firefighter’s ability to fight fire fast.
Uses of class “a” foam different uses for water treated with a class “a” foam concentrate are: Foam fire extinguishers aqueous film forming foam (afff) designed for protection of industrial and commercial premises. The type of foam these systems use is; Fluorinated surfactants are used in class b foam concentrates and are necessary to form a film on flammable liquid fires. Seattle uses a product that takes all the guesswork out of using foam, novacool uef (universal extinguishing foam). The balanced chemical system in forexpan reduces the surface tension of water to increase the penetrating power into burning class a materials.

However, by adding a small amount of class “a” foam concentrate to the water, it becomes 3 to 5 times more efficient. Class a foam concentrate is a synthetic chemical additive that reduces the surface tension of water so it can penetrate combustible fuel surfaces. Triclass fire extinguishers with an afff additive are effective on class a and b fires by cooling the burning embers of carbonaceous materials and sealing the surface of burning liquids. Class a foam concentrate is used for fire fighting wildland and structural fires which consist of ordinary combustible materials, such as paper, cloth, wood, coal and rubber.

When mixed with water it creates a foam solution that is more effective than plain water for flame knockdown and fuel cooling when used for a fire attack.

Fluorinated surfactants are used in class b foam concentrates and are necessary to form a film on flammable liquid fires. If a fire st arts to attack offices or the structure of buildings, a water extinguisher is an ideal solution.

• use for class a fires. Never mix class a and class b foam concentrates qualifications and uses Afff /foam works in two ways, firstly it provides a cooling effect to the fire to slow down the fire and other is it sealed the surface and make the fire starved of fuel and break fire triangle by eliminating fuel from the triangle and extinguish the fire. The water/foam blanket smothers the fire by not allowing air (oxygen) to access the fuel and lowers the fuel temperature to below its ignition point. Class a foam concentrate is a synthetic chemical additive that reduces the surface tension of water so it can penetrate combustible fuel surfaces.

Class “a” fuel type fire; • fires involving flammable solids, such as paper, wood, and textiles (‘class a’ fires) • fires involving some flammable liquids, such as petrol, diesel, and paint (‘class b’ fires) • fires involving electrical appliances if the extinguisher has passed the 35kv conductivity test. Class a foam is for use against class a fires such as paper, rubber, textiles and wood. For any wildland or structural brigade that has to bring its water to the scene, and has to establish water tanker shuttles, using class a foam can easily increase operational efficiency of fighting the fire. • tire fires • dumpster fires • deep seated fires in landfills or hay

The reason is that, class a foam, when properly deployed, allows the fire to be extinguished more quickly and with far less water than would be required if foam was not used. Their use of class a foam, quite simply, makes good sense for them. It helps the water penetrate the burning material to quickly suppress the fire and prevent rekindles. The surfactants used must produce foam in concentration of less than 1%.
