Class B extinguishers are specifically designed for which type of fire?

1. Wood fires

2. Electrical fires

3. Grease and oil fires

4. Fabric fires

The correct answer is: Grease and oil fires

Class B extinguishers are specifically designed to handle fires involving flammable liquids such as grease, oil, gasoline, and other combustible liquids. These types of fires require special extinguishing agents that can effectively smother the flames and prevent re-ignition. Class B extinguishing agents may include foam, carbon dioxide, or dry chemical powders that are effective in separating the fuel from the oxygen necessary for combustion. In contrast, Class A extinguishers are meant for ordinary combustibles such as wood, paper, and cloth. Class C extinguishers are tailored for electrical fires, where the risk of electric shock exists, and Class D is used for combustible metals. Understanding the specific classes of fire extinguishers ensures that individuals can choose the right type to effectively combat the respective fire safely.
