What should a lifeguard do if they witness a swimmer showing signs of fatigue?

When a lifeguard witnesses a swimmer showing signs of fatigue, the appropriate action is to watch them closely and be prepared to assist. This is crucial because signs of fatigue can quickly escalate into a dangerous situation, potentially leading to drowning if the swimmer is unable to keep themselves afloat. By monitoring the swimmer closely, the lifeguard can assess the swimmer's condition and respond promptly if their situation worsens. This proactive approach allows for immediate intervention, ensuring the safety of the swimmer.

Proper training emphasizes the importance of vigilance and readiness to act in various situations, especially when a swimmer is in distress. Continuous observation helps in identifying not just visible signs of struggle or fatigue, but also in predicting potential hazards before they arise. This approach also reflects the lifeguard's responsibility to prioritize the safety and well-being of everyone in their area of supervision.
