How far apart should notices stating "NO DIVING" be located at a pool?

Notices stating "NO DIVING" should be located 25 feet apart at a pool to ensure adequate visibility and awareness for all swimmers. This distance is significant because it helps to reinforce the warning, making it more likely that individuals will notice the signs before entering the water. The placement of these warnings is a critical safety measure, as it reduces the risk of accidents related to diving, especially in shallow areas or where diving is prohibited. Spacing the notices at this distance allows for effective communication of safety rules, ultimately promoting a safer swimming environment.
