What type of fire extinguisher is appropriate for flammable substances such as grease, oil, or gas?

• A. Type A fire extinguisher
• B. Type B fire extinguisher
• C. Type C fire extinguisher
• D. Type D fire extinguisher

Answer: (B)

A Type B fire extinguisher is specifically designed for flammable liquids, which include substances such as grease, oil, and gases. The distinguishing feature of Type B extinguishers is that they utilize agents effective for suppressing fires caused by these types of materials. The extinguishing agents often include foam, carbon dioxide, or dry chemical agents that can effectively displace oxygen or interrupt the chemical reaction occurring during the combustion of flammable liquids. Choosing a Type B extinguisher is crucial because using an incorrect type of extinguisher can potentially exacerbate the fire. For instance, a Type A extinguisher, which is meant for ordinary combustibles like wood and paper, is not suitable since these types of agents can react unfavorably with flammable liquids, leading to spreading the fire. Likewise, Type C extinguishers are intended for electrical fires, and Type D extinguishers are used for combustible metals. In summary, a Type B fire extinguisher is the correct choice for addressing fires involving flammable substances such as grease, oil, and gas, ensuring both safety and effectiveness in firefighting efforts.
