How should rescuers approach a scene involving downed power lines?

Rescuers should always approach a scene involving downed power lines with caution, treating the lines as live. This mindset is essential because downed power lines can carry electricity, posing a significant risk of electrocution to both rescuers and bystanders. Even if the lines do not appear to be arcing or sparking, they can still be energized due to various factors, such as contact with other power sources or equipment.

By treating the lines as live, rescuers ensure that they maintain a safe distance and take the necessary precautions to protect themselves and others in the vicinity. This approach emphasizes the unpredictability of electrical hazards and the need for emergency responders to prioritize safety in all circumstances.

In comparison, while protective gear is certainly important, it does not eliminate the risk posed by downed lines if caution is not exercised. Additionally, traffic management is important for overall scene safety, but it does not address the specific hazard of electricity from downed lines. Lastly, the idea of approaching without concern if no active arcing is visible undermines the essential principle of dealing with electrical hazards, which is to always err on the side of caution.
