What does a Class B fire extinguisher specifically target?

A Class B fire extinguisher is specifically designed to target fires caused by flammable liquids and gases. This includes substances such as gasoline, oil, grease, and other similar materials that can ignite and produce significant hazards. The firefighting agents used in Class B extinguishers are formulated to effectively smother the flames and cut off the oxygen supply, preventing the fire from spreading.

Understanding the classification of fires is vital for effective firefighting. Class A covers ordinary combustibles like wood and paper, while Class C deals with electrical fires. Class D is for combustible metals. Each class requires specialized handling techniques and fire extinguisher types, which is why knowing that a Class B extinguisher is aimed at flammable liquids and gases is essential for safety and effective response in emergencies.
