What is one of a lifeguard's primary responsibilities during surveillance?

One of a lifeguard's primary responsibilities during surveillance is maintaining a continuous watch over swimmers. This responsibility is crucial because it enables the lifeguard to monitor the safety of all patrons in the water, recognize any potential emergencies, and respond promptly to situations that may require their intervention. Constant vigilance helps to identify swimmers in distress, those who may be at risk of drowning, and unsafe behaviors that could lead to accidents. By focusing on this task, lifeguards ensure a safer environment for all swimmers and help prevent accidents before they escalate into emergencies. This level of attentiveness is foundational to the role of a lifeguard and is essential for effective surveillance.
