Q

Which extinguishing agent is effective in combating an isoprene fire?

🔍 Key Concepts

• Properties of isoprene (a flammable hydrocarbon liquid, similar to other flammable solvents) • Which agents are best for flammable liquid (Class B) fires • Limitations of CO2 and foam on certain types of fuel fires

💭 Think About

• Think about whether isoprene behaves more like a flammable liquid fuel, an electrical hazard, or an ordinary combustible solid when it burns • Consider which of the listed agents can both quickly knock down flames and help prevent re‑ignition of a flammable liquid surface • Ask yourself: in real shipboard practice, which one agent would you most likely be trained to use first on a small flammable liquid spill fire?

✅ Before You Answer

• Verify which extinguishing agents are generally recommended for Class B (flammable liquid) fires in maritime training materials • Check whether CO2 provides any cooling or sealing of the liquid surface to prevent re‑flash • Check which option, if any, is known as a good general‑purpose shipboard agent that can be used on many classes of fires, including flammable liquids
