What is a Class B fire?

• A. A fire involving electrical equipment
• B. A fire involving flammable liquids such as gasoline or oil
• C. A fire involving ordinary combustibles like wood and paper
• D. A fire involving cooking oils and fats

Answer: (B)

A Class B fire specifically refers to a fire that involves flammable liquids, such as gasoline, oil, and other hydrocarbons. These types of fires require specific extinguishing methods, typically involving foam, dry chemical agents, or carbon dioxide, which can effectively smother the flames and prevent the flammable liquid from reigniting. Understanding Class B fires is crucial for firefighters, as they can pose significant hazards due to the volatility of the involved materials. In contrast, the other classifications relate to different types of materials that ignite. For instance, fires involving electrical equipment classify as Class C fires, while ordinary combustibles like wood and paper fall under Class A fires. Cooking oils and fats represent Class K fires, which necessitate specialized extinguishing techniques. Recognizing these distinctions is essential for appropriate fire response protocols.
