How should a lifeguard respond to a swimmer who is distressed?

A lifeguard's primary responsibility is to ensure the safety of all swimmers, and responding appropriately to a distressed swimmer is crucial. Using a rescue tube allows the lifeguard to maintain a safe distance while providing assistance. This method facilitates a more controlled and effective rescue, as the rescue tube can be thrown to the swimmer or used to help guide them back to safety without putting the lifeguard at risk of being pulled under by a panicking swimmer. This strategic approach minimizes danger and maximizes the chance of a successful rescue.

In other scenarios, diving in immediately could lead to the lifeguard being overwhelmed or caught by the distressed swimmer. Calling for help without acting delays critical assistance and might not provide immediate aid when needed. Ignoring the situation even with bystanders present undermines the lifeguard's duty of care and could result in severe consequences for the swimmer. Therefore, the most appropriate response is to use a rescue tube to ensure the safety of both the lifeguard and the distressed swimmer.
