Look Out for Overhead Power Lines

• When working with ladders or long tools: Stay at least 10 feet away from overhead power lines carrying up to 50kV.
  
  
• When cranes and derricks are used in construction: Keep the crane boom and load at least 20 feet away from lines up to 350 kV and 50 feet away from lines greater than 350 kV but at or less than 1,000 kV. Always assume the line is energized, and allow nothing closer unless
  you have confirmed with the utility owner/operator that the line has
  been de-energized.
  
  
  • If voltage is unknown, contact the local electric utility before
    work begins.

• As voltage increases, clearance distances also increase. For specific requirements, consult the local electric utility and osha.gov.
  
  
• Clearly mark boundaries with tape, signs, or barricades to keep workers and equipment a safe distance away.

If in doubt, contact your local electric utility well in advance so safety arrangements can be made.
