Which fire extinguisher type is specifically designed for Class B fires?

A Type B extinguisher is specifically designed to combat Class B fires, which involve flammable liquids such as gasoline, oil, paints, and solvents. These extinguishers contain agents that can suppress the flames of liquid hydrocarbons by forming a barrier between the fuel and the oxygen or by interrupting the chemical reaction that is sustaining the fire.

Using the correct type of extinguisher is crucial for safe and effective fire suppression. Class B fires require specific agents, such as foam, dry chemical, or carbon dioxide, that can effectively put out fires fueled by flammable liquids, whereas other types of extinguishers are designed for different classes of fire. For instance, a Type A extinguisher is suitable for ordinary combustibles like wood and paper, a Type C extinguisher is appropriate for electrical fires, and a Type D extinguisher is designed for combustible metals. Understanding the specific applications of each type ensures that individuals can respond appropriately in fire emergencies, maximizing safety and effectiveness.
