How often should lifeguards conduct rotations to maintain alertness?

The recommendation for lifeguard rotations is every 20-30 minutes to maintain alertness and effectiveness while on duty. This duration allows lifeguards to adequately monitor the pool area without experiencing fatigue, which can lead to decreased awareness and slower response times in emergencies. Rotating more frequently would help ensure that lifeguards remain engaged and alert, particularly in active aquatic environments where the potential for incidents can vary greatly. The 20-30 minute guideline strikes a balance between ensuring effective monitoring while providing adequate time for lifeguards to remain vigilant and attentive to their surroundings. This practice is crucial in promoting safety for all swimmers and ensuring lifeguards don’t become distracted or fatigued during their shifts.
