How should signal flares be used after abandoning ship?

• A. Use them constantly regardless.
• B. Use them only during daylight hours.
• C. Do not use signal flares.
• D. Use them only when you are aware of a ship or plane in the area.

Answer: (D)

Signal flares are visual distress signals used to attract rescuers. After abandoning ship, you should fire them only when you know a ship or aircraft is in the area and could see your location. This maximizes the chances of a successful rescue because the signal is observed by someone who can respond, and it helps conserve limited flare supplies. Firing them constantly wastes resources and could confuse or mislead rescuers, while using them only in daylight isn’t practical since flares are most effective for attracting attention when visibility is reduced. In short, deploy flares when a potential observer is present to ensure your distress call is seen and acted upon.
