Electrical safety guidelines for working near overhead power lines

Power line clearance requirements in WA

In Western Australia (WA), the minimum clearance distances for working near overhead power lines are set by WorkSafe WA and the Western Australian Government. These vary depending on the voltage of the power line:

• 0.5 metres: For live insulated overhead electric lines or aerial bundled conductor lines with a voltage of up to 1,000 volts.
• 1.0 metre: For live uninsulated overhead electric lines with a voltage of up to 1,000 volts.
• 3.0 metres: For live overhead electric lines with a voltage exceeding 1,000 volts but not more than 33,000 volts.
• 6.0 metres: For live overhead electric lines with a voltage exceeding 33,000 volts.

Understanding the safety zones around overhead electrical lines is crucial for preventing accidents and ensuring safe work practices. The safety distances are set out according to Section 166A of the Work Health and Safety (General) Regulations 2022. Always check with the relevant network operator (e.g. Western Power) before starting any work near overhead power lines.

If you need to work near powerlines, it's essential to familiarise yourself with the safety guidelines to avoid hazards:

• Working in the Vicinity of Overhead Power Lines
• Guidelines for the Safety of Buildings Near Electrical Assets

Why clearance requirements matter

Failure to maintain safe distances can lead to:

• Electrocution or fatal injuries
• Fires and property damage
• Legal penalties for non-compliance
• Overhead power lines can be deceptive; electricity can “arc” through the air without direct contact, meaning accidents can occur even if you don’t physically touch the line.

Safe work practices near overhead lines

When working near power lines in WA:

• Treat all lines as live and dangerous
• Use spotters when operating machinery
• Never store materials under or near overhead lines
• Follow WorkSafe WA and Western Power guidance
