How do you extinguish a class Bravo fire in an engine room?

• A. Water Spray
• B. Foam Blanket
• C. Halon or HFP
• D. CO2

Answer: (C)

For a Class Bravo fire in an engine room, using a clean, halogenated extinguishing agent is the best approach. Halon or HFP works by interrupting the chemical reactions occurring in the flame, which stops combustion almost instantly. This is especially important in an enclosed engine room with flammable liquids and electrical equipment, because it suppresses the fire quickly without flooding the space with water or foam that could spread fuel or damage machinery. Clean agents leave little residue, so you can protect gear and minimize cleanup. Water spray could spread spilled fuel and create steam that can burn or damage equipment, making it less effective for liquid-fuel fires. Foam blankets can work on some spills, but in a crowded, confined engine room they may not reach all fuel surfaces and can complicate machinery operation. CO2 displaces oxygen and poses a serious asphyxiation hazard to personnel in an occupied space, which is unsafe in engine rooms. So, Halon or HFP is the most effective option for rapidly knocking down a Class Bravo fire in an engine room.
