Question 577 Deck Safety

The correct answer is B) sound the general alarm. The reasoning is that when a fire breaks out on a vessel, the top priority is to alert the crew and passengers so they can evacuate the area and potentially assist in firefighting efforts. Sounding the general alarm quickly notifies everyone on board so they can respond appropriately. The other options, while important, should come after the alarm is sounded to ensure the safety of all personnel. Determining the source, attempting to extinguish the fire, and stopping ventilation are all secondary actions that should be taken after the alarm is raised.
