Which minimum distance should non-electrical workers stay from live overhead power lines when operating boom lifts?

• A. 5 feet
• B. 10 feet
• C. 15 feet
• D. 20 feet

Answer: (B)

The main idea is to prevent electrical shock and arcing by keeping a safe clearance from energized overhead lines. Boom lifts can move unexpectedly, and metal parts can conduct electricity or arc across air gaps if the distance is too small. For non-electrical workers, the required minimum is ten feet from live overhead lines while a boom lift is in use. This gap accounts for movement of the equipment and the possibility of an arc reaching out to nearby parts. If the lines are higher voltage, the needed clearance increases, so always follow the voltage-specific guidelines or de-energize and relocate the equipment if in doubt.
