A galley grease fire is classified as a Class B fire. Class B fires involve flammable liquids and gases, including fuels such as gasoline, oil, grease, and many solvents. In the context of a galley or kitchen, the grease used for cooking is a flammable substance that can ignite and create a fire hazard. When fat or oil overheats, it can ignite, and if the fire is not controlled promptly, it can spread quickly. Understanding the classification of fires is crucial for effective firefighting. Class B extinguishing agents, such as foam, dry chemical, or carbon dioxide extinguishers, are designed specifically to combat fires fueled by flammable liquids like grease. In contrast, other classes of fire, such as Class A for ordinary combustibles (wood, paper, etc.), Class C for electrical fires, and Class D for combustible metals, require different types of extinguishing agents. This classification helps firefighters select the appropriate method for extinguishing a fire safely and effectively.
