Which of the following should be included when reviewing zones?

When reviewing zones, it is essential to include zone coverage diagrams as they visually represent the specific areas that each lifeguard is responsible for monitoring. These diagrams provide clarity on the layout of the pool and surrounding areas, ensuring that lifeguards understand their designated zones and can effectively communicate with one another. By having a clear plan of coverage, the entire team can work together to ensure comprehensive surveillance of all areas, which is critical for maintaining safety and preventing incidents. This preparation helps lifeguards to anticipate potential issues and respond quickly if an emergency arises, ultimately enhancing the safety of all patrons in the aquatic environment.
