In what situation would a lifeguard NOT use a rescue tube?

A lifeguard would not use a rescue tube in an emergency situation where quick action is needed and distance cannot be maintained because the primary purpose of the rescue tube is to provide buoyancy and support at a safe distance from the distressed swimmer. In urgent scenarios that require immediate intervention, the lifeguard may need to dive directly into the water to reach the individual quickly without the constraint of a rescue tube.

Using a rescue tube typically involves a careful approach to maintain distance between the lifeguard and the swimmer, which can be hindered if immediate action is required. The lifeguard's priority in such cases is to reach the swimmer as fast as possible, which might necessitate a direct contact strategy rather than using a buoyancy device that could slow the response time.

In contrast, using a rescue tube is standard practice in situations like assisting distressed swimmers in shallow or deep water, where the lifeguard can ensure safety while still maintaining distance and control. Therefore, the option indicates a scenario where the lifeguard must prioritize speed and direct intervention over the benefits of using auxiliary flotation devices.
