What immediate action should be taken if a lifeguard notices signs of distress in a swimmer?

When a lifeguard notices signs of distress in a swimmer, the most immediate action should be to alert other lifeguards. This is crucial because it ensures that additional help is available to manage the situation effectively. Lifeguarding is a team effort, and having more eyes on the situation can lead to quicker action and greater safety for the distressed swimmer.

Alerting other lifeguards allows for coordinated rescue efforts, which can include one lifeguard entering the water while others keep track of the situation and prepare to assist if necessary. This also helps in maintaining safety for both the swimmer in distress and the lifeguard attempting the rescue, as multiple lifeguards can communicate effectively to prevent further emergencies.

Jumping in the water immediately without alerting others can lead to complications, especially if the lifeguard encounters difficulties. Scanning other areas would detract from the immediate need to address the swimmer in distress, and ignoring the signs of distress goes against the fundamental responsibilities of a lifeguard. Recognizing and responding to distress promptly is key to ensuring the safety of swimmers under their watch.
