Class A, B, and C fires are categories used to classify different types of fires based on the materials or substances involved. These classifications help determine the appropriate firefighting methods and extinguishing agents to effectively combat the fire. Here's what each class represents:
Class A fires involve ordinary combustible materials such as wood, paper, cloth, rubber, and plastics (that do not contain halogens). These fires typically leave behind ash when burned. Class A fires are among the most common types of fires encountered. Extinguishing agents for Class A fires include water, foam, and dry chemical extinguishers. These agents work by cooling the fire, smothering it, or interrupting the chemical reaction of the combustion process.
Class B fires involve flammable liquids or gases, such as petrol, oil, grease, propane, and solvents. These fires may produce a visible flame and can spread rapidly if not properly contained. Class B fires do not leave behind ash; instead, they produce a residue that may greasy. Extinguishing agents for Class B fires include foam, carbon dioxide (CO2), dry chemical powders, and specialized extinguishing agents designed to smother the fire or interrupt the chemical reaction of the combustion process.
Class C fires involve energized electrical equipment or wiring. These fires pose a unique challenge because water-based extinguishing agents can conduct electricity and pose a risk of electrical shock to firefighters. Class C fires can occur in switch panles, transformers, wiring, and other electrical devices. Extinguishing agents for Class C fires include carbon dioxide (CO2), dry chemical powders, and halon alternatives specifically formulated for use on energized electrical equipment. These agents are non-conductive and can extinguish the fire without posing a risk of electrical shock.
