What action should a WSI take when spotting a distressed swimmer?

When spotting a distressed swimmer, the appropriate action is to perform a rescue or alert a lifeguard immediately. This is crucial because a distressed swimmer may be unable to signal for help or may not have the strength to reach safety on their own. Acting promptly ensures that the swimmer receives the necessary assistance as quickly as possible, reducing the risk of drowning or further distress.

Alerting a lifeguard, if one is present, activates emergency protocols that can provide immediate support. Performing a rescue directly, if safe to do so, can save vital seconds and may be the difference between life and death. The key point in this scenario is that swift, decisive action is essential to ensure the safety of the distressed swimmer and prevent the situation from worsening.

In contrast, ignoring the situation fails to address the immediate danger, waiting for the swimmer to signal prolongs their distress, and simply notifying others to stay calm does not address the urgent need for intervention. Therefore, the most responsible and effective response is to take action to assist the distressed swimmer or to inform a lifeguard for proper rescue response.
