What should a lifeguard do if they notice a change in a swimmer's behavior?

Taking immediate action to check on the swimmer's safety is crucial when a lifeguard notices a change in a swimmer's behavior. Changes in behavior can be indicative of distress, fatigue, or other issues that may compromise the swimmer's safety. By acting promptly, the lifeguard can assess the situation, determine the swimmer's condition, and provide necessary assistance. This proactive approach is essential for preventing potential accidents or emergencies.

Observing the swimmer for a short time, while sometimes appropriate in identifying patterns, may not be sufficient if the behavior indicates immediate risk. Failing to act can lead to serious consequences, including injury or drowning. Additionally, informing other staff members and ignoring the situation does not address the issue directly and could leave the swimmer vulnerable. Prioritizing assigned duties over the swimmer's safety overlooks the lifeguard's primary responsibility, which is to ensure the well-being of all patrons in the water. Thus, taking immediate action is the correct course of action in this scenario.
