What should vessels do when they observe a false distress signal?

When vessels observe a false distress signal, the appropriate action is to immediately report it to the relevant authorities. This is crucial because false distress signals can divert resources and attention away from genuine emergencies. By reporting the incident, authorities can investigate the situation, potentially locate the source of the false signal, and take necessary action to prevent confusion and ensure the safety of all vessels in the area.

Ignoring a false distress signal could lead to serious consequences if a real emergency were occurring nearby, as it risks delaying critical response efforts. Attempting to signal back may complicate matters further, as the original signaler may not be in a position to respond, and it does not provide any definitive information about their intent. Recording the event for personal records does not contribute to resolving the situation and may instead contribute to a lack of response where one is urgently needed.
