This page provides information and tips for being safe when you're around our lines, towers and substations.
To ensure your own personal safety around transmission lines you can read:
- Approach to land under and beside transmission lines
- Information on electric and magnetic fields
- Safety resources
- What you should do before you dig
If you see anything wrong with a Transpower line, or someone in danger around a line, phone our emergency 24-hour hotline 0800 THE GRID immediately.
Follow these tips when you’re around our lines, towers and substations:
- Treat all lines as live at all times.
- Never climb transmission towers (pylons), poles or other structures.
- Do not attempt to enter a substation switchyard.
- Do not touch or go near a fallen wire (conductor).
- Do not light fires under or near lines without first discussing it with Transpower or your network company.
- Do not fly kites or flying models near lines.
- Use extreme care when handling long metal objects such as pipes or ladders near lines.
- Use extreme care when running out or straining fence wires near lines. Always check for power lines where fence wires may be pulled under tension, such as across gullies.
- Use extreme care when moving or using boats with masts, cranes, diggers, scaffolding, work platforms or buckets (cherry pickers) or any other tall objects near transmission lines – keep at least four metres away from the conductors.
- Do not sail or launch boats with tall masts under lines.
- Do not connect metallic objects like fence wires or clothes lines to transmission structures.
- Do not build, excavate, dump or stockpile fill or plant trees close to a transmission line.
- Electricity can jump from transmission line wires (conductors). You do not have to touch them to be killed – just being close can be dangerous! Always keep yourself or anything you are touching at least four metres away from the lines.
- Pilots – always be aware of transmission lines and other overhead wires when using helicopters, aerial topdressing aircraft and microlights.
- If you are working near power lines (such as farming, building or operating machinery) you are required by health and safety legislation to control the risks and ensure your own safety and that of others.
