When working outside, be sure to look up and note the location of power lines before you start. Never touch the lines with your person or the tools you are using and stay at least ten feet from power lines.
Careful avoidance of power lines is extremely important during exterior and yard work — especially when using ladders, paint extender poles and other tools. Be sure that ladders or scaffolding are far enough away so that neither your body or the tools you’re using come within ten feet of any power lines. You could be seriously injured or even killed if you or an object you are holding contacts a power line, including television antennae and satellite dishes.
If you’re a contractor, be sure all vehicles, derricks, cranes and other tall machinery have more than ten feet of clearance from the power lines. Making contact can be costly and dangerous.
