Which class of fire involves flammable liquids?

The correct classification for fires involving flammable liquids is Class B. This category encompasses a wide range of combustible liquids, including gasoline, oils, solvents, and any other substances that can ignite and produce a flame.

Understanding the nature of Class B fires is crucial for proper firefighting techniques and the selection of appropriate extinguishing agents. For instance, water is not suitable for extinguishing Class B fires, as it can cause the flaming liquid to spread and worsen the situation. Instead, specific foam, dry chemical, or carbon dioxide extinguishers designed for Class B fires must be used to effectively suppress the flames and prevent re-ignition.

Different classes of fire include specific materials; for example, Class A pertains to ordinary combustibles like wood and paper, Class C includes electrical fires, and Class D relates to combustible metals. Knowing these distinctions is essential for safety and effective firefighting.
