What class fire extinguisher should be used to safely extinguish a flammable liquid?

Class B fire extinguishers are specifically designed to combat fires involving flammable liquids, such as gasoline, oil, grease, and solvents. The extinguishing agents commonly found in Class B extinguishers can effectively suppress fires created by these materials by either removing the oxygen or cooling the burning liquid. The focus on flammable liquids distinguishes this class from others, which are intended for different types of fires.

For instance, Class A extinguishers are meant for ordinary combustibles like wood and paper, while Class C extinguishers are suitable for fires involving electrical equipment. Class D extinguishers are designed for combustible metals, which are not typically found in other fire scenarios. Understanding these classifications is crucial for ensuring safety in the presence of various fire hazards.
