🔍 Key Concepts

• Class B fires (flammable liquids) commonly found in engine room bilges • How foam and water fog behave on burning fuel vs solid stream water • Danger of spreading burning oil with the wrong extinguishing agent

💭 Think About

• What type of fuel is usually burning in a bilge fire, and what fire class does that make it? • Which extinguishing agents will smother and cool burning oil without splashing or spreading it? • How does a solid stream of water behave when it hits a pool of burning oil compared with low-velocity fog?

✅ Before You Answer

• Confirm that bilge fires are usually oil/flammable liquid fires, not ordinary combustibles. • Eliminate any options that would agitate or spread a pool of burning oil (think solid water jets). • Look for the combination that both forms a blanket over the fuel and gently cools without splashing.
