What clearance is required when operating near high voltage power lines rated at 33kV?

When operating near high voltage power lines rated at 33kV, maintaining a clearance of 10 feet is crucial for safety. This distance is established to prevent accidental contact with the power lines, which can lead to severe electrocution hazards for crane operators and crew members. The 10-foot clearance requirement is based on industry standards aimed at reducing the risk of electrical hazards associated with overhead power lines.

The rationale behind this specific clearance distance is to account for the voltage's potential to induce electrical currents and the possibility of lines swaying or moving due to environmental factors like wind or operational factors like crane movement. By adhering to the 10-foot clearance, crews can work in proximity to these lines without compromising safety, thereby minimizing the risks associated with high voltage electricity.
