What is a critical step to take before approaching a rescue victim?

Assessing personal safety and environmental conditions is crucial before approaching a rescue victim because it ensures that the rescuer is fully aware of the potential dangers that could affect both themselves and the victim. This assessment includes evaluating factors such as water current, weather conditions, and any hazards in the environment, such as unstable banks or submerged objects. Understanding these elements allows the rescuer to make informed decisions about the safest way to approach the situation, reducing the risk of further injuries or complicating the rescue. Prioritizing personal safety means that rescuers can be in a position to help effectively rather than becoming victims themselves during the rescue attempt.
