Final Answer:

Class B fire extinguishers are used for flammable fires involving liquids and gases.

Explanation:

Class B fire extinguishers are specifically designed to combat fires involving flammable liquids and gases, such as gasoline, oil, propane, and natural gas. These extinguishers are typically filled with agents like carbon dioxide (CO2), dry chemical powders, or foam, which work by smothering the fire and interrupting the chemical reaction of the flames with oxygen.

This type of extinguisher is essential in environments where flammable liquids and gases are present, such as laboratories, workshops, garages, and industrial facilities. Using the appropriate Class B extinguisher is crucial for effectively and safely extinguishing fires fueled by liquids and gases, minimizing the risk of injury and property damage.
