A rescue tube is a flotation device designed to assist in water rescues. Typically made of buoyant materials, it is lightweight and easy to throw to someone in distress. Lifeguards often use rescue tubes at pools, beaches, and other aquatic environments to help individuals stay afloat until they can be safely brought to shore. These tubes are usually bright in color, making them easily visible in the water. They often come with a strap or rope attached, allowing rescuers to pull a person to safety. Proper training in using rescue tubes is essential for effective and safe rescues in emergency situations.
