For power lines rated at 300 kV, what minimum clearance is required when the crane is in transit according to OSHA 1926.1411?

The minimum clearance required when a crane is in transit near power lines rated at 300 kV is ten feet. This standard is in place to ensure the safety of workers and machinery around high voltage power lines, as the risk of electrical shock increases with proximity to live electrical sources. Maintaining this clearance helps to prevent accidental contact with the power lines, which can lead to severe injuries or fatalities.

The ten-foot clearance requirement allows for a safety buffer that accounts for both the height of the crane and any potential movement or sway of the equipment during transit. Ensuring this distance is adhered to is a crucial part of crane operation safety and aligns with industry guidelines set by OSHA to protect workers on construction sites.
