What are the five basic classifications of fire? The five fundamental classifications of fires are widely recognized in various fields of study. These include Class A, Class B, Class C, Class D, and Class K. Class A fires involve common combustibles, such as wood, paper, or cloth. Conversely, Class B fires involve flammable liquids or gases such as gasoline, most paint, most oil, and alcohol. Class C fires are those that involve electrical equipment, such as clothes dryers, wiring, cords, and space heaters. Class D fires involve combustible metals, such as sodium and lithium, while Class K fires involve cooking oils and fats, such as vegetables and grease. These classifications are essential in fire safety and prevention, as they provide a framework for identifying the appropriate extinguishing agents and strategies for each type of fire. Explain the various types of agents used to extinguish or control fires in these five classifications. In the fire suppression realm, various agents may be employed to extinguish or control fires. These agents may be broadly classified into five distinct categories: water, halon, foam, dry chemical extinguisher, and dry powder. Class A fires, typically fueled by paper, wood, or plastic, are best tackled using water, dry chemicals, or fire blankets. Class B fires, generally fueled by flammable liquids such as gasoline or oil, can be effectively handled using halon, dry chemical fire extinguishers, or foam. Class C fires, which involve electrical equipment, a dry chemical extinguisher is the most appropriate choice. Class D fires, which involve combustible metals, can be successfully suppressed using dry powder. Class K fires, associated with cooking oils and greases, are best extinguished using water mist, foam, and fire suppression blankets. Reference: https://firefightergarage.com/classes-of-fire/
