Which type of fire extinguisher is specifically designed to put out fires caused by flammable liquids?

The correct choice is designed specifically for dealing with fires that involve flammable liquids, such as gasoline, oil, or grease. These types of fires are classified as Class B fires. Type B fire extinguishers use substances like foam, carbon dioxide, or dry chemical agents that are effective in smothering the flames and preventing oxygen from fueling the fire.

Type A extinguishers, on the other hand, are intended for ordinary combustibles like wood, paper, and cloth, which are not suitable for combating flammable liquid fires. Type C extinguishers are designed for electrical fires, while Type D extinguishers are meant for combustible metals. Understanding the right type of extinguisher to use in different fire situations is crucial for safety.
