Which fire extinguisher classification is suitable for flammable liquids?

Fire extinguishers are classified based on the type of fire they are designed to extinguish. For flammable liquids, the appropriate classification is Class B. This category specifically addresses fires fueled by combustible liquids such as gasoline, oil, and other solvents.

Class B extinguishers work by smothering the fire, cutting off the oxygen supply, and often using agents such as foam, dry chemical powders, or CO2 to effectively suppress the flames. In contrast, the other classifications target different types of fires: Class A is for ordinary combustibles like wood and paper, Class C is for electrical fires, and Class D targets combustible metals. Therefore, understanding these classifications is crucial for selecting the right extinguisher for the fire type at hand, ensuring both safety and effectiveness in an emergency situation.
