What type of fire is a fuel or oil fire classified as?

A fuel or oil fire is classified as a Class B fire because Class B fires involve flammable liquids and gases, including fuels like gasoline, oils, and other petrochemical products. These types of fires cannot be extinguished with water, as it can spread the fire further. Instead, they require specific extinguishing agents that can effectively smother the flames or separate the fuel from the oxygen supply. Understanding this classification is crucial for selecting the appropriate firefighting methods and equipment to manage such fires safely and effectively. The other classes pertain to different materials: Class A covers ordinary combustibles like wood and paper, Class C is related to electrical fires, and Class D involves combustible metals, which are not applicable to fuel or oil fires.
