What is the first step a lifeguard should take when someone is in trouble in the water?

The first step a lifeguard should take when someone is in trouble in the water is to assess the situation and determine the safest way to reach the victim. This is crucial because it allows the lifeguard to evaluate the environment and the conditions of the water, including potential hazards such as strong currents, waves, or obstacles, as well as the behavior of the victim. By assessing the situation, the lifeguard can determine the best approach for the rescue while minimizing risks to both themselves and the person in distress.

A hurried jump into the water without proper assessment can lead to additional problems, such as putting the rescuer in danger or failing to provide effective assistance. Calling for backup is important in many situations but is secondary to understanding the rescue dynamics first. Blowing a whistle may alert others, but it is not a primary action when immediate assistance is necessary. Therefore, the logical and safest course of action starts with a thorough assessment of the scenario.
