Which type of fire extinguisher should you use for an engine fire caused by flammable liquids?

Using a Type B fire extinguisher for an engine fire caused by flammable liquids is correct because Type B extinguishers are specifically designed to put out fires involving flammable liquids such as gasoline, oil, and grease. These extinguishers typically use materials like foam, graphite, or dry chemical agents to smother the flames and prevent the fire from spreading.

Understanding the classification of fire extinguishers is vital for safety. Type A extinguishers are intended for ordinary combustibles such as wood or paper, while Type C extinguishers are used for electrical fires. Type D extinguishers are suitable for fires involving combustible metals, which is not relevant in the case of an engine fire caused by flammable liquids. Therefore, selecting a Type B extinguisher is essential for effectively combating this type of fire and ensuring the safety of everyone on board.
