Which type of fire extinguisher is specially designed for use on flammable liquids and gases?

The selection of the Class B fire extinguisher is appropriate because it is specifically designed to combat fires involving flammable liquids and gases, such as gasoline, oil, grease, and certain solvents. These types of fires can spread rapidly and require specialized extinguishing agents that are effective on fuel-based materials. Class B extinguishers typically contain foam, carbon dioxide, or dry chemical agents that can smother and extinguish the flames safely and effectively, preventing re-ignition.

By understanding the classification of extinguishers, one recognizes that each type is tailored to tackle specific fire scenarios. Class A extinguishers, for example, focus on ordinary combustibles like wood and paper, while Class C extinguishers are meant for electrical fires. Class D extinguishers, on the other hand, are specialized for flammable metals. Each class serves a distinct purpose, highlighting the importance of selecting the appropriate extinguisher for the specific type of fire encountered.
