According to OSHA 1926.1408, what is the minimum clearance between any part of the crane/load and 850kV energized overhead power lines?

25 ft.
30 ft.
35 ft.
45 ft.

The correct answer is: 45 ft.

The correct answer is based on OSHA regulations, specifically 1926.1408, which address safety standards for cranes operating near energized overhead power lines. For power lines carrying 850kV, the regulation mandates a minimum clearance of 45 feet between any part of the crane or the load being lifted and the power lines. This minimum clearance is crucial for ensuring the safety of crane operators and workers on site, as high voltage lines create significant risks of electrical hazards, including potentially fatal electric shocks. The larger clearance distance reflects the increased voltage and the corresponding risk associated with it. Maintaining this safe distance helps to prevent accidents and provides adequate protection for personnel and equipment. Therefore, adhering to this regulation is essential for safe crane operation around high-voltage power lines.
