Am
I In Danger?
Overhead and buried power lines at your site are especially
hazardous because they carry extremely high voltage. Fatal
electrocution is the main risk, but burns and falls from elevations
are also hazards. Using tools and equipment that can contact
power lines increases the risk.
Examples
of Equipment That Can Contact Power Lines
- Aluminum
paint rollers
- Backhoes
- Concrete
pumpers
- Cranes [For additional information, see
Cranes and Derricks]
- Long-handled cement finishing floats
- Metal
building materials
- Metal
ladders
- Raised
dump truck beds
- Scaffolds [For additional information, see 29 CFR 1926.451(f)(6)]

How Do
I Avoid Hazards?
- Look for overhead power lines and buried power line
indicators. Post warning signs.
- Contact utilities for buried power line locations.
- Stay at least 10 feet away from overhead power lines.
- Unless you know otherwise, assume that overhead lines are
energized.
- De-energize and ground lines when working near them. Other
protective measures include guarding or insulating the lines.
- Use non-conductive wood or fiberglass ladders when working
near power lines.

Overhead power lines are un-insulated and can carry tens of
thousands of volts, making them extremely dangerous to employees who
work in their vicinity.
