Class B fires involve fuels such as:

Class B fires are associated with flammable liquids and gases. These fuels include substances such as gasoline, oil, paint, and solvents, which can easily ignite and produce intense flames. The identification of Class B fires is critical for effective firefighting strategies, as they require specific approaches that differ from those used for other classes of fires. For example, water should not be used on Class B fires, as it can spread the flammable liquid and make the situation worse. Instead, specialized extinguishing agents, such as foam or dry chemical agents, are typically employed to effectively suppress these fires and prevent re-ignition. Understanding the types of materials involved in Class B fires is important for both fire safety education and emergency response planning.
