What should a lifeguard do if they see a swimmer displaying signs of fatigue?

When a lifeguard observes a swimmer showing signs of fatigue, the appropriate action is to approach the swimmer and offer assistance. This is crucial because a fatigued swimmer may be at risk of drowning if no intervention is made. By approaching the swimmer, the lifeguard can assess the situation more closely to determine the level of assistance needed.

Offering assistance can take many forms, such as providing verbal encouragement, monitoring the swimmer's condition, or initiating a rescue if necessary. The lifeguard’s training emphasizes the importance of intervention when potential danger is identified, as timely assistance can prevent a situation from escalating into a more serious incident.

Using a rescue device, calling for backup, or ignoring the swimmer are not safe or effective strategies for ensuring the swimmer’s safety and wellbeing. Therefore, actively assisting the swimmer is the best course of action in this scenario.
