A lifebuoy is a circular flotation device designed to save people from drowning in water. Typically made of buoyant materials, it is often brightly colored, making it easy to spot in emergencies. Lifebuoys are commonly found near swimming pools, beaches, and on boats, and they are usually equipped with a rope for easy retrieval. When someone falls into the water, a lifebuoy can be thrown to them, allowing them to grab hold and stay afloat until help arrives. These devices are an essential part of water safety equipment and are used by lifeguards, boaters, and swimmers to prevent drowning incidents.
