What should a lifeguard do first when they notice a swimmer in distress?

When a lifeguard notices a swimmer in distress, the first step should be to assess the situation before taking any further action. This assessment is crucial as it allows the lifeguard to evaluate the swimmer's condition and the environment, which are critical factors in determining the safest and most effective course of action.

By assessing the situation, the lifeguard can identify whether the swimmer is merely struggling or in immediate danger, as well as whether there are any hazards present, such as underwater obstructions or currents that might complicate a rescue. This careful evaluation also enables the lifeguard to consider their own safety and the safety of others around them.

Taking this preliminary step helps ensure that the lifeguard can respond effectively and choose the most appropriate method of rescue, rather than rushing in without understanding the full context, which could lead to further complications or danger for both the lifeguard and the distressed swimmer.
