What is the first step a lifeguard should take if someone is suspected of drowning?

The first step a lifeguard should take if someone is suspected of drowning is to call for help and enter the water if it is safe to do so. This action is crucial because it ensures that assistance is on the way while also allowing the lifeguard to act quickly to rescue the individual in distress.

Calling for help alerts other lifeguards or emergency personnel, making sure that more resources are available for the situation. Entering the water only if it is safe prevents the lifeguard from putting themselves in danger, which is important for their own safety and for the successful execution of the rescue. If a lifeguard jumps in without assessing the situation or calling for backup, it could lead to additional complications or even make the situation worse by jeopardizing their safety.

Waiting for someone else to respond or shouting at the individual in distress does not address the immediate need for rescue and could lead to further complications as time is critical in drowning situations. Thus, the most effective approach involves communication and assessment before entering the water to ensure both the lifeguard's and the drowning person's safety.
