When working on a boom lift, you should stay at least how many feet away from power lines?

• A. 5
• B. 15
• C. 20
• D. 10

Answer: (D)

Keeping a safe clearance from electrical power lines when operating a boom lift is essential because electricity can arc through the air to the equipment even without direct contact. The platform and its metal components can become energized, putting you at serious risk of shock or electrocution if you get too close. The standard minimum distance used in training is ten feet for lines up to 50 kV, which provides a practical buffer against arc and flashover under typical conditions. If the line carries higher voltage or conditions are wet or windy, you must increase that clearance or de-energize the line and follow proper procedures. Always maintain the prescribed distance, use a spotter, and avoid reaching beyond the platform edges toward the lines.
