Question 580 Deck Safety

The correct answer is D) immediately. Control of fire should be addressed immediately because fire poses an immediate threat to the safety of the vessel and crew. Quickly containing and extinguishing a fire is critical to prevent it from spreading and causing further damage or endangering lives. This is a fundamental principle of maritime safety and is a key focus area in the US Coast Guard Captain's License Examinations. The other answer choices are incorrect because they do not reflect the priority of addressing a fire threat. Restoring vital services, establishing fire boundaries, and controlling flooding are all important, but they should not take precedence over the immediate control of an active fire.
