What are the safe working distances when operating machinery near overhead power lines?

2025-08-07

The safe working distance, also known as the minimum approach distance, is the closest a person or piece of equipment can get to a live power line. This distance is a non-negotiable safety measure defined by regulations like OSHA and is dependent on the voltage of the line. For example, a common rule is to maintain a 10-foot clearance for voltages up to 50 kV, with this distance increasing for higher voltages.

To prevent accidents, our company highly recommends the following:

  • Plan Ahead: Always contact the utility owner to confirm the voltage and clearance requirements before beginning work.

  • Utilize Spotters: A dedicated spotter is essential to provide constant guidance to equipment operators.

  • Use Physical Barriers: Install elevated warning lines, goalposts, or barricades to clearly mark the danger zone.

Our specialized power line tools and accessories are integral to executing these safety measures, enabling your team to work securely and efficiently around high-voltage infrastructure.
