A life ring, also known as a life buoy, is a circular flotation device designed to save lives in water emergencies. Typically made of buoyant materials, it is brightly colored for high visibility and often features reflective strips. Life rings are commonly found near swimming pools, beaches, and on boats, ready to be thrown to someone in distress. When someone falls into the water and struggles to stay afloat, a life ring can be tossed to them, allowing them to grab hold and stay above water until help arrives. They are an essential safety tool, often used in conjunction with other rescue equipment like lifeguard stations and rescue boats.
