What kind of materials are involved in Class B fires?

• A. Electrical devices
• B. Common combustibles
• C. Flammable liquids such as gasoline
• D. Combustible metals

Answer: (C)

Class B fires are characterized by the combustion of flammable liquids and gases. These materials include substances like gasoline, oil, grease, and solvents, which can easily ignite and spread flames due to their low flash points. When dealing with Class B fires, it's crucial to use the appropriate extinguishing agents, as water can exacerbate the situation by spreading the flammable liquid. Understanding the material involved in Class B fires helps in selecting the correct fire suppression methods and ensuring safety during fire emergencies. This distinguishes Class B fires from other classes, such as Class A, which involves common combustibles like wood and paper, or Class C, which primarily includes electrical devices.
