The choice emphasizes safety for both the lifeguard and the swimmer. It allows the lifeguard to maintain a safe distance from potential struggles with a distressed swimmer, which can be dangerous in turbulent water or if panic sets in. The buoyancy of the rescue tube helps keep the swimmer afloat, allowing the lifeguard to take necessary action without immediate physical contact, thus enhancing the chances of a successful rescue without compromising the lifeguard's safety.

A thorough swim test involves assessing a swimmer's abilities rather than the active rescue context in which a rescue tube is vital. Signaling for help is a function of communication but does not reflect the direct use of the rescue tube itself. Increasing visibility during
