Which class of fire extinguisher is specifically designed for use on flammable liquids?

Class B fire extinguishers are specifically designed for fires involving flammable liquids such as gasoline, oil, grease, and paints. These types of fires can be particularly dangerous because they have the potential to spread quickly and cause extensive damage. Class B extinguishers use substances like foam, carbon dioxide (CO2), or dry chemical agents, which can effectively smother the flames and prevent re-ignition.

In contrast, Class A extinguishers are meant for ordinary combustibles like wood, paper, and cloth. Class C extinguishers are suitable for electrical fires, while Class D extinguishers are designed for combustible metals. Understanding the appropriate class of fire extinguisher for different types of fires is crucial for effective fire safety and emergency response.
