🔍 Key Concepts

• Properties of Ethane as a cargo (flammable gas, not a liquid fuel like alcohols or oils) • Typical fixed and portable fire-extinguishing systems for liquefied flammable gases on gas carriers • The role of dry chemical vs. foam vs. water fog when dealing with gas fires

💭 Think About

• Is Ethane more like a gasoline/oil fire, an alcohol/polar-solvent fire, or a liquefied flammable gas fire, and how does that change the best extinguishing method? • Which agents are most effective at quickly breaking the flame’s chemical reaction in a gas fire, and which are better for cooling surrounding structures? • Among the options, which agent combinations are designed specifically for gas fires rather than liquid pool fires?

✅ Before You Answer

• Verify whether alcohol foam is intended for polar-solvent liquid fires or for flammable gas fires. • Check how dry chemical agents are described for use on LPG/LNG or liquefied gas fires in firefighting guidance. • Confirm the primary use of water fog in gas carrier fires (cooling boundaries and dispersing vapors vs. directly extinguishing the burning gas).
