In what scenario would a lifeguard use a rescue buoy rather than entering the water?

Using a rescue buoy is appropriate when the victim is far from the shore. This scenario allows the lifeguard to provide assistance without putting themselves at risk by swimming long distances in potentially hazardous conditions. The buoy acts as a flotation device, allowing the victim to grasp onto it for support, which can help keep them afloat while the lifeguard secures a safe plan for rescue or communication. The use of the rescue buoy helps maintain a safe distance and reduces the risk of a lifeguard becoming overwhelmed or needing assistance themselves.

The other scenarios do not emphasize the need for a buoy to the same extent. For example, in cases of swift water rescue, immediate entry may be necessary, while conscious victims can often follow instructions or assist themselves. During a typical swim, the proximity to safety or assistance often negates the need for a buoy, as the situation does not demand a rescue.
