What is the safest procedure when working around energized overhead power lines with mobile equipment?

When working around energized overhead power lines with mobile equipment, ensuring safety is paramount. The safest procedure is to have the local electrical authority cut off power. This method eliminates the risk of electric shock or electrocution by removing any potential electrical hazards before work begins.

Cutting off power ensures that no accidental contact with the power lines will lead to serious injuries or equipment damage. This precaution is critical when there is a possibility that equipment could come too close to the energized lines.

Other safety measures, such as wearing insulated gloves, using a signalman, or staying inside the equipment, may reduce some risks but do not provide the same level of safety as ensuring the power is completely cut off. If the lines remain energized, even with protective measures in place, there is still a significant risk involved. Thus, the best practice is to completely de-energize the lines before proceeding with any work activities in that area.
