Tree Work Near Power Lines

Every year, tree workers, landscapers and homeowners are electrocuted when a branch, pole saw, ladder or their own body comes too close to a power line. A tree touching a line can be energized, and electricity can jump from the line to you without direct contact.

• Landscaping & tree work
• Storm cleanup
• Homeowners

Who can work near the lines

• Line-clearance tree trimming close to energized lines may be done only by qualified line-clearance arborists, trained and equipped for that work under OSHA’s utility rules and ANSI Z133.
• Everyone else, including general tree crews, landscapers and homeowners, must keep themselves, their tools and the tree parts they handle at least 10 feet from lines up to 50 kV, and farther for higher voltages.
• If a job requires getting closer, call the utility. They may trim, de-energize or cover the line.

Hidden dangers

• Branches touching or near lines may be energized; don’t touch the tree
• “Fiberglass” pole saws and ladders can conduct when dirty or wet; they’re not protection
• Cut limbs can swing or fall into lines
• Service drops (lines to houses) carry deadly voltage too
• Wind and wet weather increase the risk

Before tree work

• Look up and around; identify every line near the tree, including service drops
• Estimate whether any part of the tree, your tools or equipment could come within 10 feet
• Plan the fall direction so nothing can hit a line
• Call the utility if the work can’t stay clear
• Brief the crew, including ground workers handling ropes and limbs
• Never climb a tree that touches a line

Homeowners

Never prune trees near power lines yourself. Most utilities trim trees near their lines for free, or will drop service lines temporarily so a professional can work safely. Call before you cut.
