What specific type of fire does Class B represent?

• A. Fires involving ordinary combustibles
• B. Fires involving flammable liquids
• C. Fires involving electrical equipment
• D. Fires involving metals

Answer: (B)

Class B fires specifically refer to those that involve flammable liquids, which include substances like gasoline, oil, paints, and solvents. These fires can occur when liquids ignite or when volatilized vapors from these liquids come into contact with an ignition source. It is critical to understand that Class B fires require particular extinguishing agents, such as foam, carbon dioxide, or dry chemical agents designed to smother the flames and cut off their oxygen supply. Recognizing the correct class of fire is essential for effective fire prevention and response, as the wrong type of fire extinguisher can exacerbate the situation or fail to extinguish the fire entirely. In contrast, Class A fires involve ordinary combustibles like wood and paper, Class C fires pertain to energized electrical equipment, and Class D fires involve combustible metals, each requiring specific approaches for effective control and extinguishment.
