What should lifeguards observe in patrons besides swimming ability?

Lifeguards are trained to monitor various aspects of patrons' behavior, as it is crucial for ensuring safety in the aquatic environment. Observing behavior indicators allows lifeguards to detect potential issues that may arise, such as distress, unsafe playing, or signs of fatigue. These indicators are essential for recognizing when a patron may need help or may be involved in risky activities that could lead to incidents.

Understanding behavior also encompasses noting group dynamics, as certain groups may engage in behavior that could increase the chances of accidents, such as roughhousing or excessive splashing. By focusing on these behavior indicators, lifeguards can proactively intervene and maintain a safe environment for all patrons in the pool area. The other choices, while they may have some relevance to overall safety, do not directly pertain to immediate risk assessment and intervention in the same way. For example, swimming times and water temperature do not provide insight into patrons’ immediate behavior or safety needs.
