In the mid-1880s, Class A foams were developed for pugnacious wildfires. To lower the surface tension of the water, Class A foams reinforced in dowsing and to drench all Class A agents by means of liquescent. All these means supports fire suppression and will avert re-ignition. Auspicious familiarities directed in the direction of its recognition meant for battling additional types of Class A fires, as well as structure fires ("Army Safety Program," 2013).
Therefore, Klaus (2013) defines Class B foams as it was intended for Class B fires which take account of igneous solutions. Nevertheless, usage of Class A foam on a Class B fire possibly will return …show more content…
Synthetic foams arrange for enhanced stream and more rapid extinguish and restraint flames, nonetheless narrow fire security. Such synthetic foam is known as aqueous film forming foams. Aqueous film forming foams are water based and commonly comprise of hydrocarbon based surfactant such as sodium alkyl sulfate, and fluorosurfactant, such as fluorotelomers, perfluorooctanoic acid, or perfluorooctanesulfonic acid (Klaus, 2013). All having the capability to extend fully over the surface of hydrocarbon based liquids. Alcohol resistant aqueous film forming foam are foams impervious to the action of alcohols, capable to assemble a shielding film when
