Which type of fire extinguisher is appropriate for flammable liquid fires?

• A. Class A extinguisher
• B. Class B extinguisher
• C. Class C extinguisher
• D. Class D extinguisher

Answer: (B)

The classification of fire extinguishers is based on the type of material that is burning. Flammable liquid fires, which include fires involving fuels like oil, gasoline, and solvents, are categorized as Class B fires. Therefore, a Class B extinguisher is specifically designed to tackle these types of fires effectively.

Class B extinguishers utilize agents such as foam, dry chemical, or carbon dioxide, which work by suffocating the fire or preventing the flammable vapors from igniting. This quality makes them suitable for tackling flammable liquid fires, as they help to control the problem without spreading the flames further.

In contrast, other classes of extinguishers cater to different types of fires. Class A extinguishers are intended for ordinary combustibles like wood and paper, Class C extinguishers target electrical fires, and Class D extinguishers are used for combustible metals. Thus, understanding the specific classes helps ensure that the right extinguisher is used for the correct type of fire, maximizing safety and effectiveness in emergency situations.
