What minimum distance should aerial devices be kept away from powerlines?

• A. 20 feet
• B. 5 feet
• C. 15 feet
• D. 50 feet

Answer: (A)

Keep in mind that electricity can arc across a gap and energize equipment even without direct contact. Aerial devices must stay well clear of lines to prevent electrocution and equipment damage, and a 20-foot margin provides a practical buffer against line sag, wind gusts, ice, and the movement of the ladder or platform as you operate it. This distance helps ensure you won’t come within the range where arcing or unintended contact could occur while extending, positioning, or adjusting the apparatus. In situations involving higher voltages, greater clearances may be required by policy or code, but for standard procedures, 20 feet is the safe minimum.
