In what situation should a lifeguard use a rescue buoy?

Using a rescue buoy is particularly effective when reaching for a swimmer at a distance because it allows a lifeguard to provide flotation and support while maintaining a safe distance. The buoy can be thrown or extended toward the swimmer, enabling them to grasp it for support without the lifeguard needing to be in close proximity, which is especially important if the swimmer is panicking or struggling. This technique helps to maintain the lifeguard's own safety and control the situation, reducing the risk of being pulled under by a distressed swimmer.

In this context, other scenarios do not utilize the rescue buoy as effectively. In shallow waters, the lifeguard might be able to reach the swimmer more easily without the buoy. For a swimmer who is injured and cannot swim, more direct assistance may be necessary which the buoy alone may not provide. With a panicking swimmer, while the buoy can be helpful, directly reaching them is often required instead of solely relying on the buoy for assistance.
