When is it appropriate for a lifeguard to empty a pool?

The appropriate reason for a lifeguard to empty a pool is when there is a serious safety concern. This could involve situations such as a potential contamination of the water, a structural issue with the pool itself, or other hazards that pose a risk to swimmers' safety. In such circumstances, the immediate priority is the health and safety of all patrons. Therefore, clearing the pool is essential to prevent accidents or health hazards.

While routine maintenance is important, it is typically planned and notified to patrons, allowing for alternative arrangements. Patron requests or the pool's busyness do not warrant a decision to empty the pool, as safety should always be the primary concern guiding such actions.
