🔍 Key Concepts

• Behavior of burning oil on water (spreads out, floats on surface) • How different extinguishing agents work: dry chemical, foam, solid water stream, water fog • Danger of spreading burning liquid with the wrong extinguishing method

💭 Think About

• Think about what happens if you hit a pool of burning oil on water with a solid stream of water. Does that push and spread the oil or gently smother it? • Which agent can form a blanket over the surface of the burning oil to cut off oxygen and prevent re‑ignition? • If you direct an agent at the side of the vessel instead of directly onto the burning surface, what effect are you trying to create?

✅ Before You Answer

• Which option is least likely to spread the burning oil over a wider area? • Which method creates a smothering blanket over the oil rather than disturbing the liquid surface? • Which choice would be considered standard practice for flammable liquid fires on water in marine firefighting training?
