What class of fire involves flammable liquids?

The class of fire that involves flammable liquids is classified as B-class fires. This category encompasses fires fueled by substances such as gasoline, oil, paints, and solvents, which are typically characterized by their ability to ignite and combust rapidly. Understanding this classification is crucial for effective firefighting as it informs the selection of appropriate extinguishing agents. For example, B-class fires are best controlled with foam, dry chemical powder, or carbon dioxide extinguishers, which are specifically designed to smother flames and cut off the oxygen supply to the burning liquid.

Other classifications, such as A-class fires, involve ordinary combustibles like wood or paper; C-class fires pertain to electrical hazards; while D-class fires involve combustible metals. Each type requires unique firefighting strategies and materials, making it essential for personnel to recognize these distinctions in order to respond safely and effectively during fire emergencies.
