What type of fire is classified as Class B?

Class B fires are specifically categorized as those involving flammable liquids, such as gasoline, oils, and solvents. Understanding this classification is crucial for effective firefighting strategies and safety measures.

Flammable liquids can produce vapors that are ignitable, and the fire may spread quickly due to the nature of these substances. Firefighters must use the appropriate extinguishing agents, such as foam or dry chemical extinguishers, which are designed to smother the fire and prevent re-ignition by cutting off the oxygen supply or preventing the release of flammable vapor.

In contrast, other fire classifications address different types of materials: Class A fires involve ordinary combustible materials like wood and paper, Class C fires pertain to electrical equipment, and Class D fires are related to combustible metals. Recognizing these distinctions enables firefighters to tailor their approach to each situation effectively and safely.
