A lifebuoy ring, also known as a life ring or lifebuoy, is a critical lifesaving device designed for emergency water rescues. Typically circular and buoyant, it is thrown to a person overboard to keep them afloat while rescue operations are underway. Made from durable materials like polyethylene, it resists harsh marine conditions and UV rays. Lifebuoy rings are often equipped with reflective tape and grab lines for increased visibility and handling. Commonly found on ships, docks, pools, and offshore platforms, they are essential safety equipment that meets international marine safety regulations and ensures compliance with SOLAS standards.
