What action should a rescuer take before trying to assist a victim in the water?

Before attempting to assist a victim in the water, it is crucial for a rescuer to assess the water conditions. Understanding the environment where the rescue will take place is vital for ensuring both the rescuer's safety and the victim's well-being. Factors such as water depth, current strength, temperature, and visibility can significantly affect the outcome of the rescue operation.

By evaluating these conditions beforehand, a rescuer can make informed decisions about the appropriate rescue method and whether entering the water is safe. This type of assessment helps to mitigate risks and create a safer environment for both the rescuer and the victim, aligning with best practices in water rescue training.

Other actions, like estimating the risk of drowning or determining if help is available, are also important but naturally follow after understanding the immediate context of the rescue. Calming and reassuring the victim, while essential to assist with their anxiety, cannot precede the assessment of the situation—it is critical to ensure the rescuer can approach the scenario safely first.
