How should a lifeguard react if they see a swimmer in distress?

When a lifeguard observes a swimmer in distress, the appropriate response is to assess the situation and then initiate a rescue if necessary. This approach is crucial because it allows the lifeguard to evaluate the severity of the swimmer's distress and determine the best course of action. Factors such as the swimmer's condition, the environment, and potential risks are considered before proceeding with a rescue to ensure the safety of both the swimmer and the lifeguard.

Jumping in immediately without assessing the situation could lead to unnecessary risks, such as not being aware of any dangers that may affect the lifeguard or the swimmer. Similarly, ignoring the situation can be extremely dangerous, as it may result in a life-threatening scenario for the swimmer. Calling for help and waiting for others to respond is not ideal either, as it delays necessary assistance and may increase the risk for the distressed swimmer. Therefore, the best practice is to first assess the situation and then act accordingly with appropriate rescue techniques.
