An inflatable buoy (20) that may be worn by a person, such as a swimmer, and used as a flotation aid and beacon in an emergency situation. The buoy (20) has securing means (2a) for being secured to a forearm (3) of a person, an inflatable balloon (4a) that when uninflated is disposed on the securing means (2a) and when inflated is separate from the securing means (2a), a tether (7a) anchoring the balloon (4a) to the securing means (2a), and a gas dispenser (30a) that, when activated, inflates the balloon (4a) with gas. The buoy (20) also has a pair of handles (21) for gripping by a person as well as a pop-up flag (22). In another embodiment of the invention, the buoy may be used as an air beacon whereby the balloon is filled with gas that is lighter than air and the balloon can float to a height determined by the length of the tether.
