Which of the actions listed should be carried out immediately after securing the fires in one boiler of a two- boiler ship?

🔍 Key Concepts

• Safe shutdown procedures for a fuel‑fired marine boiler • What happens inside a boiler when you suddenly stop firing but still have pressure and water present • Which systems must stay in service to protect the boiler after you secure the fire

💭 Think About

• After you put out the burner flame, which part of the fuel system is still actively pushing oil toward that boiler? • Which systems must continue running so the boiler can cool down and maintain proper water level and pressure control? • Which listed actions could actually damage the boiler by causing thermal shock or loss of level/pressure control if done immediately?

✅ Before You Answer

• Identify which choice directly addresses fuel supply/pressure to the boiler just secured • Eliminate any choice that would cause sudden cooling with air or water (thermal shock risk) • Confirm that you would NOT immediately secure anything that is still needed to safely cool down and control the boiler (like feed systems)
