When approaching a river during a rescue operation, what should be the first step?

Conducting a visual assessment of the scene is essential when approaching a river during a rescue operation as it allows rescuers to gather critical information before taking any further actions. This step involves evaluating the conditions of the water, identifying potential hazards such as debris, currents, and obstacles, and observing the victim's situation. A thorough visual assessment helps in determining the safest and most effective approach for the rescue, ensuring that rescuers can plan their actions wisely and minimize risks to both the victim and themselves.

By taking the time to assess the scene first, rescuers can also evaluate environmental factors such as weather conditions and water temperature, which play a significant role in risk assessment. This foundational step helps inform subsequent actions, such as the type of rescue equipment needed and the entry points into the water, rather than rushing into the rescue without sufficient information or preparation.
