OSHA 29 CFR 1910.269: What is the crane minimum clearance distance from power lines?

• A. Crane minimum clearance distance of 10 feet from power lines
• B. Crane minimum clearance distance of 5 feet from power lines
• C. Crane minimum clearance distance of 15 feet from power lines
• D. Crane minimum clearance distance of 20 feet from power lines

Answer: (A)

The essential point is maintaining a safe clearance from energized power lines to prevent electric shock or arcing during crane operations. OSHA 29 CFR 1910.269 sets a baseline minimum clearance of 10 feet from overhead lines energized parts for crane work near typical distribution lines (up to about 50 kV). This 10-foot distance accounts for crane movement, sway, and potential contact with the line, providing a practical margin for operator reaction and load handling.

If you know the line voltage is higher, the required clearance increases accordingly. For example, 15 feet is specified for lines in the 50–200 kV range, and about 20 feet for voltages in the 200–350 kV range. In everyday crane work near standard distribution lines, 10 feet is the general minimum to follow, with greater distances used for higher voltage scenarios.

So the 10-foot minimum is the best-supported baseline answer, reflecting the fundamental safety standard for most crane operations near power lines. Always verify the exact distance in the applicable table for the line voltage at hand and use additional precautions such as spotters, de-energizing lines when possible, or employing passive barriers if needed.
