| Overhead Power Line Clearances |
|
| Maintaining the proper clearance from overhead power lines is not only critical to a safe work environment, it’s the law. Before you start work, call Southern California Edison at 1-800-611-1911 to verify voltages and determine required safety clearances. |

| The Deal on Clearances |
| Here are some key rules to remember: |
| • |
When working with ladders or long tools: Keep yourself and all tools and equipment at least 10 feet away from overhead power lines carrying up to 50 kV. |
| • |
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 SCE before work begins. |
|
| • |
As voltage increases, clearance distances also increase. For specific requirements, consult SCE and osha.gov. |
|
| • |
Clearly mark boundaries with tape, signs or barricades to keep workers and equipment the required distance away. |
|
| • |
Always use a dedicated spotter on the ground to help you stay clear of power lines. |
|
|
| If you must work closer than regulations allow, contact SCE at 1-800-611-1911 well in advance so safety arrangements can be made. |
| Don’t Forget |
| Power lines are not insulated. Always consider them energized and dangerous. Any contact with overhead lines could cause serious injury to equipment operators and ground crew. |
