What does the signal PAN PAN indicate?

The signal PAN PAN is recognized as an urgent message that conveys an immediate concern regarding the safety of a ship or personnel. It indicates a situation where there is a need for urgent assistance but does not suggest that the situation is life-threatening or requiring immediate rescue, which is the distinction between PAN PAN and a distress call. This signal is used to alert other vessels or authorities that there is a potential issue that requires prompt attention, allowing them to prepare to assist if necessary.

In maritime communication, the proper understanding of these signals is crucial for effective emergency response. Knowing that PAN PAN conveys urgency helps ensure that both the sender and receivers give appropriate priority to the situation at hand.
