Class B Fires Analysis

The ability to combat fires and to suppress fires, a fire fighting agent had to be developed to lower the heat within the fire and to subdue the cause, avoiding oxygen to be in contact with the source. In 1902, Aleksandr Loran, a chemist and engineer from Russia invented a foam fighting or fires. ("Army Safety Program," 2013). Proxies that generate high expansion foams consume an enormous area expansion ratio. High expansion foams are appropriate for sealed off capacities for instance, large buildings with vulnerable open spaces, where the rapid filling is required.
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
