When a Fire extinguisher is a Class B. What type of fire will be put out by this extinguisher?

A Class B fire extinguisher is designed to put out fires involving flammable liquids, gases, and greases, such as gasoline, oil, paint, and solvents. These materials can produce volatile vapors that can ignite easily, making it essential to use the correct type of extinguisher to effectively suppress the fire. Class B extinguishers typically contain foam, carbon dioxide, or dry chemical agents to smother the flames and prevent re-ignition.
