What is the minimum crane clearance for power lines rated at 100 kV according to OSHA 1926.1408?

• A. Ten feet with encroachment precautions
• B. Fifteen feet with encroachment precautions
• C. Twenty feet
• D. Twenty-five feet

Answer: (B)

The minimum crane clearance for power lines rated at 100 kV according to OSHA 1926.1408 is set at fifteen feet with encroachment precautions. This distance is specified to ensure safety when operating cranes in proximity to high-voltage power lines. The rationale behind this requirement is to protect both crane operators and ground personnel from the hazards of electrical contact, which can pose serious risks of electrocution or electric shock. Encroachment precautions may include utilizing spotters, warning devices, or increased training for personnel working near these power lines. Such measures reinforce the importance of maintaining a safe operational distance from electrical sources to prevent accidents. Therefore, adhering to the fifteen feet clearance guideline is crucial for the safe use of cranes around power lines rated at 100 kV.
