🔍 Key Concepts

• Class B fires (flammable liquids like oil and gasoline) and how they are normally extinguished • How water behaves when sprayed on burning oil on water (does it sink, mix, spread, or smother?) • How foam and dry chemicals work on oil fires (smothering and vapor suppression)

💭 Think About

• For each option, ask: will this method spread the burning oil, or will it smother and contain it on the water’s surface? • Think about why firefighters avoid using solid water streams directly on burning liquid fuels. What happens to the fuel when hit hard with water? • Between fog, solid water streams, dry chemical, and foam, which is best at forming a continuous blanket over the oil on the water’s surface?

✅ Before You Answer

• Verify which agents are specifically recommended for oil (flammable liquid) fires on water in standard firefighting guidance • Check which methods are likely to break up and spread the burning oil (these are poor choices) • Focus on the option that can create a floating, smothering blanket over the fuel rather than just cooling it
