Which type of fire extinguisher is appropriate for flammable liquids?

The appropriate type of fire extinguisher for flammable liquids is class B. This class is specifically designed to combat fires that involve combustible liquids such as gasoline, oil, paint, and solvents. Class B extinguishers use agents such as foam, carbon dioxide, or dry chemical powders to smother the flames and prevent the fire from spreading. The effectiveness of these extinguishers arises from their ability to create a barrier between the fire and the oxygen needed for combustion, making them essential for dealing with flammable liquid fires safely and effectively.

In contrast, class A extinguishers are intended for ordinary combustibles like wood and paper, class C extinguishers are designed for electrical fires, and class D extinguishers are used for fires involving flammable metals. Each type of extinguisher targets specific risks based on the materials involved, which is why using the correct class is crucial for effective fire suppression.
