What is the main requirement for children aged 12-15 years in a pool when lifeguards are not present?

For children aged 12-15 years in a pool when lifeguards are not present, the primary requirement is that they must be accompanied by an adult. This guideline is designed to ensure the safety and supervision of younger swimmers, as this age group may not have the maturity or experience to manage potential risks in the water effectively. Having an adult present can provide immediate assistance if an emergency arises and allows for easier monitoring of the child's swimming abilities and behavior in the pool.

The requirement for adult supervision is critical in both private and public settings, as it reflects a commitment to safety and responsible swimming practices. By ensuring that young swimmers are accompanied by an adult, the likelihood of accidents decreases, and children can be educated on safe swimming habits in a controlled environment.
