What action should a lifeguard take if encountering poor visibility while searching for a guest?

When a lifeguard encounters poor visibility during a search for a guest, utilizing snorkels and masks is a proactive and effective method to enhance the search. These tools allow the lifeguard to see more clearly underwater, increasing the chances of locating the guest quickly and safely. In conditions of poor visibility, relying on standard observation may not be sufficient, as a lifeguard may not be able to see submerged individuals or objects clearly.

Employing snorkels and masks optimizes the lifeguard's ability to navigate underwater and identify any presence of guests in distress, which is crucial for ensuring their safety. This approach demonstrates an understanding of the situational challenges and uses available resources to improve the search efficiency.

Alternative actions, such as continuing the search without assistance, waiting for conditions to improve, or rescuing everyone in sight immediately, do not address the specific challenge of low visibility in a focused and effective manner. Each of these actions lacks the targeted improvement that snorkels and masks provide, which is essential in potentially life-threatening situations.
