🔍 Key Concepts

• Heat transfer in a shipboard fire: conduction through decks and bulkheads • Use of cooling water streams to protect decks and boundaries above a fire • The dangers of heat and structural damage to areas directly above a fire

💭 Think About

• Think about what happens to the metal deck directly above a very hot fire—how does that affect people standing on it and the ship’s structure? • Which option matches standard boundary cooling techniques used in shipboard firefighting? • Which choice, if taken literally, would clearly be unsafe for your crew when a space below is burning intensely?

✅ Before You Answer

• Identify which option shows protective cooling rather than exposing personnel to more danger • Eliminate any choice that would keep people standing on or very near overheated metal above a fire • Confirm which action aligns with basic boundary cooling and crew safety principles in shipboard firefighting manuals
