The Alpha Flag, also known in maritime communication as the "Diver Down" flag, is a distinguishing flag used to indicate that a diver is in the water and to instruct vessels to keep a safe distance. The design of the Alpha Flag features a swallowtail shape, which is split in half. One half of the flag is white, and the other half is blue. This specific design is crucial for ensuring visibility and conveying a clear message regarding diver safety.

This flag is widely recognized in maritime operations, making it essential for all seafarers to understand its appearance and significance. The colors and shape are tailored to stand out against the backdrop of the sea, thereby maximizing its visibility to approaching vessels and ensuring that they can take appropriate action to avoid any accidents involving divers.
