Which flag indicates that personnel are working both over the side and aloft?

The correct answer identifies the flag that signifies that personnel are working both over the side and aloft. The flag associated with this condition is the Kilo Three flag. This information is particularly important for maintaining safety and awareness on a vessel, as it signals the need for caution to other personnel and vessels in the vicinity.

Kilo flags, in general, are used to communicate specific activities on a ship. When the Kilo Three flag is displayed, it means that there are individuals working at heights and over the edge of the ship, drawing attention to the potential hazards involved. This flag serves as a critical tool for coordinating operations and ensuring that both the crew and those outside the vessel are aware of the activities taking place, reinforcing safety protocols on board.

Understanding such flag signals is vital for anyone in a naval or maritime environment as it aids in effective communication and helps to prevent accidents during operations.
