Which class of fire extinguisher is specifically designed for flammable liquids?

• A. Class A fire extinguisher
• B. Class B fire extinguisher
• C. Class C fire extinguisher
• D. Class D fire extinguisher

Answer: (B)

Class B fire extinguishers are specifically designed for combating fires involving flammable liquids, such as gasoline, oils, solvents, and paints. These extinguishers use agents that can effectively suppress flames without spreading the fire or causing a violent reaction. Common extinguishing agents for Class B fire extinguishers include foam, carbon dioxide (CO2), and dry chemical powders that are formulated to interrupt the chemical reaction of the fire. In contrast, Class A fire extinguishers are used for ordinary combustibles like wood, paper, and cloth. Class C fire extinguishers are intended for electrical fires, while Class D fire extinguishers are designated for combustible metals. Each class serves a specific type of fire hazard, and using the correct class is crucial for effective fire suppression. Therefore, the classification of Class B makes it the appropriate choice for fires involving flammable liquids.
