Class B fire extinguishers are designed for which type of fires?

Class B fire extinguishers are specifically designed to extinguish fires that involve flammable liquids, such as gasoline, oil, grease, and solvents. These kinds of fires can spread rapidly and require extinguishing agents that can effectively smother the flames or interrupt the chemical reactions that sustain the fire. Class B extinguishers typically use substances like foam, carbon dioxide, or dry chemical agents that are effective against this type of fire.

Understanding the classification of fire extinguishers is crucial for effective firefighting. Class A extinguishers are for ordinary combustibles like wood and paper, while Class C extinguishers are meant for electrical fires, and Class D extinguishers are used for flammable metals. Each class is tailored to address specific materials, emphasizing the importance of using the correct type of extinguisher to safely handle a given situation.
