What does the Kilo One flag indicate?

The Kilo One flag, also known as the "Kilo" flag, is a signal used in maritime communication to indicate that there is a person working over the side of the ship. This flag serves as a warning to other vessels to maintain a safe distance from the ship during operations that involve personnel working on or near the waterline. Its primary purpose is to ensure the safety of individuals engaged in these tasks and to prevent potential accidents or injuries.

Understanding the significance of the Kilo One flag is crucial for maintaining safety protocols in maritime operations, particularly when personnel are at risk due to their proximity to the edge of the vessel. In contrast, the other flags mentioned serve different purposes: for instance, the flag indicating a vessel in dry dock or the one denoting that sailors are on liberty communicates different operational statuses that do not pertain directly to safety regarding personnel working over the side.
