What action should you take if you observe a person fail to surface after submersion in murky water?

Undertaking a rescue attempt in the scenario where you observe a person fail to surface after submersion in murky water is the appropriate action to ensure the safety of the individual in distress. In such situations, time is critical, and immediate intervention can be crucial. Since the person has not resurfaced, there is a significant risk that they may be in trouble and require assistance.

Taking prompt action can help prevent drowning or any further complications. Lifesaving protocols prioritize the safety of individuals in distress, especially in environments where visibility is low, like murky water.

While alerting other lifeguards and utilizing a flashlight may be helpful in some situations, the immediate concern is the person’s safety. Waiting for them to surface is not advisable as it could lead to a delay in delivering potentially life-saving assistance. Therefore, entering the water promptly to perform a rescue is essential in this urgent situation, demonstrating the importance of a proactive approach when someone's wellbeing is at stake.
