What is the recommended minimum clearance required when operating mobile equipment near high voltage lines over 1000 kV?

The recommended minimum clearance required when operating mobile equipment near high voltage lines over 1000 kV is 45 feet. This distance is established to ensure the safety of personnel and equipment from the dangers associated with electrical arcing, which can occur when a conductor is energized. The significant voltage level underscores the need for a larger safety buffer compared to lower voltage lines, as the risk and potential impact of an electrical incident increases with voltage.

Maintaining this minimum clearance helps prevent accidental contact with electric lines, which can lead to severe injury or fatality. Also, the greater distance is crucial for accommodating any potential swinging movements of the mobile equipment, as well as allowing for a safety margin in unpredictable situations like equipment failure or environmental factors such as wind. Overall, complying with the 45-foot clearance is essential for ensuring a safety-first approach on job sites near high voltage installations.
