Class B extinguishers are specifically designed for fires involving flammable liquids, such as grease or fuel. They contain special agents that will smother the fire by creating a barrier between the oxygen and the fuel source. Class A extinguishers are designed for fires involving ordinary combustibles such as paper, wood, or cloth. Class C extinguishers are designed for fires involving electrical equipment, while Class D extinguishers are designed for fires involving flammable metals. Using the wrong class of extinguisher could actually make the fire worse, so it is important to use the correct one for the specific type of fire.
