Which of the following is an example of Class B fire hazard?

• A. Wood
• B. Grease
• C. Paper
• D. Cloth

Answer: (B)

Grease is a Class B fire hazard because it’s a flammable liquid. Class B fires involve liquids that can ignite and spread, such as oils, fuels, and greases. The other items—wood, paper, and cloth—are solid combustibles and burn as Class A fires. When dealing with a grease fire, avoid water, since it can spread the burning liquid. Use an extinguisher rated for Class B (or a multipurpose ABC extinguisher) or smother the fire with a metal lid or baking soda for a small, contained fire.
