What type of fire does a Class B extinguisher combat?

• A. Electrical fires
• B. Flammable liquids and gases
• C. Ordinary combustibles
• D. Cooking oils and fats

Answer: (B)

A Class B extinguisher is specifically designed to combat fires that involve flammable liquids and gases. This includes substances such as gasoline, oil, grease, and paint, which can be volatile and produce rapid spreading flames. Class B extinguishers typically use agents such as foam, carbon dioxide, or dry chemical powders to suffocate the fire or interrupt the chemical reaction fueling it. Understanding the classification of extinguishers is crucial for effectively managing fires, as using the wrong type could exacerbate the situation. For example, applying water to a Class B fire can spread the flames instead of extinguishing them, as water does not separate flammable liquids from their source. This is why Class B extinguishers are essential in environments where there are flammable substances, ensuring that individuals have the right tools to respond to such incidents safely.
