What should a lifeguard do if they notice a swimmer having difficulty?

The appropriate response when a lifeguard notices a swimmer having difficulty is to contact backup immediately. This action is crucial as it ensures that additional support is on its way while the lifeguard assesses the situation and takes necessary steps to assist the distressed swimmer. The priority in such scenarios is to address potential emergencies swiftly and effectively, minimizing the risk of drowning or serious injury.

Calling for backup not only expedites assistance but also allows the lifeguard to focus on the swimmer in distress. Relying solely on one person may delay critical response time, especially if the situation escalates. Engaging other swimmers, waiting to see if the individual resolves the problem themselves, or ignoring the situation could lead to catastrophic outcomes, as these approaches do not prioritize the safety and immediate needs of the swimmer experiencing difficulty.
