Effective surveillance while scanning the swimming pool is crucial for ensuring the safety of swimmers and can prevent accidents. The key aspect of effective surveillance is the ability to continuously move your head and scan all depths of the water, which allows you to monitor the activities of swimmers effectively. This comprehensive scanning technique helps lifeguards detect any signs of distress, variations in swimmer behavior, or potential dangers that may not be immediately visible from a fixed viewpoint.

This method enables lifeguards to quickly identify situations that require immediate attention, such as someone struggling below the surface or any hazardous conditions that may arise at varying depths. Merely watching the surface of the water or focusing only on areas with more patrons may lead to overlooking critical signs of trouble in less populated or deeper areas. Adjusting the lifeguard chair height, while it may provide a better overall view, does not substitute for the active and thorough scanning required to ensure the safety of all individuals in the pool.
