What safety measure should be taken when using a ladder near power lines?

Ensuring the ladder is non-conductive and maintaining a safe distance from energized lines is vital for safety when working near power lines. Non-conductive ladders, typically made of fiberglass, help prevent electricity from traveling through the ladder and potentially causing severe injury or death if an electrical current comes into contact with it. This is especially crucial because metal ladders can conduct electricity, posing an increased risk when used near energized lines.

Moreover, keeping a safe distance from power lines is essential in preventing accidental contact. The National Electrical Safety Code specifies minimum distances that should be observed, which can vary depending on the voltage of the power lines. By adhering to these safety measures, workers substantially reduce the risk of electrical hazards.

While other options may offer some level of safety, they do not address the critical aspects of electrical hazards and proper ladder selection in environments with power lines.
