What should a lifeguard do if they can no longer see some patrons due to glare?

A lifeguard's primary responsibility is the safety of all patrons in their designated area, which includes maintaining an unobstructed view of everyone at all times. When glare obstructs visibility, it is crucial for the lifeguard to adapt their scanning methods to ensure that all patrons can be seen clearly.

Adjusting position to reduce glare or conducting a walking scan allows the lifeguard to find a better angle of observation where visibility is improved. By changing positions, they can minimize the impact of bright reflections or sunlight that could hinder their ability to monitor the area effectively. A walking scan also helps cover a wider area and can ensure that no patrons are overlooked. This proactive approach emphasizes the importance of being vigilant and responsive to changing conditions in the environment.

Other options do not address the need for visibility. Ignoring the glare could lead to dangerous situations where patrons may be at risk without the lifeguard's knowledge. Using sunglasses might help somewhat, but it doesn’t solve the core problem of positioning and visibility. Informing patrons to behave quietly does not aid in reducing glare and does not contribute to the lifeguard's need to maintain effective surveillance.
