Which of the following actions indicates that a swimmer is in trouble?

When a swimmer calls for help, it is a clear indication that they are experiencing difficulty and require assistance. This behavior demonstrates a recognition of their struggle and a willingness to seek aid, which is critical for lifeguards and water safety personnel to notice immediately. Swimmers who are in trouble may have exhausted their energy or encountered unexpected hazards, making their call for help an urgent signal for intervention.

In contrast, when a swimmer moves freely in the water or has a relaxed posture, it typically suggests they are comfortable and in control of their swimming abilities. Swimming towards another swimmer can also represent normal swimming behavior, possibly indicating that they are seeking company or assistance, rather than being in distress. Therefore, recognizing the nuances of a swimmer’s behavior is essential in assessing their safety, with vocalizing distress being the most direct indicator that intervention is necessary.
