What type of extinguisher is suitable for fires involving flammable liquids?

A Class B fire extinguisher is specifically designed to combat fires that involve flammable liquids such as gasoline, oil, grease, and certain solvents. This type of extinguisher contains agents like foam, dry chemical, or carbon dioxide that effectively suffocate and extinguish the flames by disrupting the combustion process or removing the heat.

Class A extinguishers are intended for ordinary combustible materials such as wood and paper, while Class C extinguishers are meant for electrical fires. Class D extinguishers are suited for fires involving combustible metals. Each class of extinguisher targets different types of fire hazards, making it crucial to select the correct one to ensure an effective response to a fire incident. Therefore, the suitability of the Class B extinguisher for flammable liquid fires is clear, as it is formulated to address the unique challenges posed by such fires.
