You are asked: what is the correct sequence of actions if a fire is discovered in the engine room while the main engine is running, and why is the order of these actions important?

A. Raise the alarm and inform the bridge/Master immediately, initiate emergency shutdowns/stops for fuel and ventilation to the affected space as appropriate (without isolating systems needed for the immediate emergency response, such as fire pumps), evacuate personnel and account for them, and only release fixed firefighting media (e.g. CO2) once the space is confirmed fully evacuated, boundaries are cooled/sealed, and ventilation/dampers are closed

B. The order does not matter as long as all actions are eventually completed

C. Release the fixed CO2 system immediately upon discovering the fire, before any other action, to extinguish it as fast as possible

D. Shut down all electrical power on the vessel first, before raising the alarm

A. Nothing — a test lift can proceed immediately after repairs

B. Testing should wait until cargo operations begin

C. The area within the grab's swing radius should be cleared of personnel before the lift

D. Only the crane operator needs to be aware the lift is happening

A. Who must remain clear of the exclusion zone while the lift takes place

B. The lunch schedule for the deck team
