What minimum clearance is commonly required from energized lines during lifting?

• A. 2 feet (0.6 meters)
• B. 0 feet when using rubber pads
• C. 50 feet
• D. Generally at least 10 feet (3 meters) or more per local regulations.

Answer: (D)

When lifting near energized lines, the danger is that electricity can arc to the crane or load or energize metal parts, causing severe shocks or fires. A conservative, widely used safety practice is to keep a substantial clearance between the crane and any live lines. The commonly required minimum is at least 10 feet (about 3 meters), though the exact distance can be greater depending on line voltage and local regulations. This gap helps account for crane movement, wind, and load sway so arcing or contact is unlikely. Rubber pads on the ground do not provide reliable insulation for this scenario, and relying on them is unsafe. While some situations may require larger distances, 10 feet or more is the typical baseline you’ll encounter in many codes and guidelines. Always check and follow local regulations and coordinate with the utility if lines cannot be de-energized.
