Which valve should be opened first when charging the ship's fire main from a shore connection in order to prevent over-pressurization of the house system and the shore connection hose?

Correct Answer: Option C — The fire main bleeder valves at the after fire stations on the main deck

Opening the fire main bleeder valves first allows for a controlled pressure equalization when connecting to a shore supply. This prevents a sudden pressure surge or 'water hammer' effect that could damage the ship's internal piping, gaskets, or the shore-side hose connection, ensuring a safe transition to shore water.
