Class B fires involve which type of fuel?

• A. Liquid
• B. Gas
• C. Metal
• D. Electrical

Answer: (A)

Fires in this classification are defined by the fuel involved. Class B is for flammable liquids, such as gasoline, solvents, and oils. The defining idea is the fuel’s liquid form and its ability to spread and pool, which changes how you fight the fire (cooling and blanket/retaining the liquid rather than just burning the solid fuel). That’s why liquid is the best answer. Other fuels map to different categories: metals form Class D fires, solids like wood or paper form Class A, and electrical fires are Class C (or electrical) fires. In some systems, gas isn’t categorized as Class B, so it’s treated separately from flammable liquids.
