What is the minimum clearance established by OSHA 1926.1408 for cranes near power lines rated above 50kv?

The minimum clearance established by OSHA 1926.1408 for cranes working near power lines that are rated above 50kV is 10 feet with additional precautions. This standard recognizes the increased risk associated with higher voltage power lines, which can pose dangers due to the potential for electrical arc and shock.

Maintaining a clearance of 10 feet allows for a safe working distance, but it is essential to implement additional precautions due to the heightened risk of electrocution and the potential for power lines to sway or sag. This can include using insulating materials, limiting the operation of cranes near these lines, or using spotters to ensure safe operation.

Understanding this regulation is crucial for ensuring safety in construction environments, especially where heavy machinery operates in proximity to high-voltage power sources. Complying with these guidelines helps protect workers from the serious hazards associated with electrical lines.
