A rescue tube is a flotation device commonly used by lifeguards and emergency responders to assist individuals in distress in water. It is typically made of buoyant materials and is designed to be lightweight and easy to throw. The tube often features a strap for the rescuer to hold onto while providing support to the person in need. Rescue tubes are essential tools in aquatic safety, especially in places like swimming pools, beaches, and water parks. They help ensure quick and effective rescues, allowing lifeguards to reach individuals who may be struggling to stay afloat or are in danger of drowning.
