Which operational code is used to indicate a man overboard situation?

In maritime communication, the operational code that indicates a man overboard situation is "OSCAR." This code is part of the International Code of Signals, which is designed to convey important messages between vessels using a standardized set of flags and signals. When a vessel displays the "OSCAR" signal, it alerts others in the vicinity that immediate assistance is required for a person who has fallen overboard, prompting quicker and more coordinated rescue efforts.

The other operational codes represent different situations or requests. For example, "PAPA" refers to the need for assistance with a vessel that is in distress, "BRAVO" is commonly used to indicate the presence of explosive materials aboard, and "FIVE" does not have an operational code significance in this context. Understanding these codes is vital for ensuring safety and effective communication on the water.
