How should a lifeguard approach a swimmer signaling trouble?

When a lifeguard approaches a swimmer signaling trouble, doing so calmly and assertively is crucial. This approach helps to establish trust and communicate effectively with the distressed swimmer. A calm demeanor can help prevent panic both in the lifeguard and the swimmer, creating a more controlled environment for assessment and potential rescue.

Being assertive ensures that the lifeguard conveys authority and confidence, which can be pivotal in guiding the swimmer. The swimmer may be experiencing fear, confusion, or disorientation, and an assertive approach signals that the lifeguard is in command of the situation and ready to help.

This method also allows the lifeguard to quickly assess the situation and take necessary actions without further escalating the swimmer’s distress. Other approaches, such as being aggressive, avoidant, or indifferent, could lead to confusion or an inadequate response to the swimmer's needs, which may worsen the situation. Thus, approaching the swimmer in a calm yet assertive manner is the most effective way to ensure safety and facilitate a successful rescue.
