What safety measure should be taken when lifting near power lines?

Maintaining a safe distance from power lines or using insulating barriers is crucial when lifting near electrical sources to prevent electrocution or electrical accidents. Power lines can carry high voltage, and any contact or even close proximity can create a dangerous situation due to electric arcs, which can jump distances depending on voltage and environmental conditions.

By ensuring a proper distance, you can significantly reduce the risk of accidental contact with the lines, which could cause severe injuries or fatalities. Using insulating barriers adds an additional layer of protection, helping to provide a separation between the lifted load and the electrical hazard, thereby enhancing safety during operations.

While other options may involve general safety practices, they do not specifically address the hazards associated with lifting near power lines. For instance, using a heavier load does not mitigate the risks presented by electricity, and time of day or clothing factors do not play a significant role in electrical safety. Thus, maintaining distance and using barriers is the most effective strategy in this scenario.
