🔍 Key Concepts

• Consult the Chemical Data Guide for Bulk Shipment by Water entries for ethyl chloride (also called chloroethane) • Consider how water and foam interact with liquefied flammable gases and whether they might spread the fire • Compare how CO2 and older chemical agents behave in terms of cooling vs. smothering a flammable gas fire

💭 Think About

• Is ethyl chloride primarily a flammable liquid, a liquefied gas, or something else, and how does that affect extinguishing methods? • Would applying water-based foam potentially spread or react with this cargo, or is a non‑aqueous agent preferred? • Among the listed agents, which is still recommended and commonly used today for flammable gas fires on chemical tankers?

✅ Before You Answer

• Verify in the Chemical Data Guide whether water spray/foam is recommended, restricted, or to be avoided for ethyl chloride • Check which extinguishing agents are identified as preferred vs. "unsuitable" for this specific cargo • Confirm whether any listed agent is obsolete or no longer recommended for marine chemical firefighting
