What occurs during a lifeguard rotation?

During a lifeguard rotation, one lifeguard relieves another at a designated station. This procedure is essential for ensuring that all stations remain monitored while providing lifeguards with necessary breaks and opportunities to rest. It helps to maintain vigilance and prevent fatigue, which is critical for effective surveillance and response to emergencies. When a lifeguard takes their turn at a station, they take over the responsibility for observing patrons and ensuring safety, allowing the previous lifeguard to either take a break or transition to a different assigned duty, enhancing the overall operational efficiency of the lifeguard team.

The other choices describe actions that may not accurately reflect the primary purpose of a lifeguard rotation. While taking breaks and switching stations can occur, they are not the focal point of a rotation, which primarily involves the transition of responsibilities from one lifeguard to another at the same post.
