Exclusion zones and safety laws

Exclusions zones keep people, operating plant and vehicles a safe distance from energised overhead powerlines. No part of a worker, operating plant or a vehicle should enter an exclusion zone while the overhead powerline is energised (live).

What’s an exclusion zone?

An exclusion zone is a minimum safe distance that must be kept from powerlines to reduce the risk of electric shock. People, operating plant and vehicles must stay out of an exclusion zone while an overhead powerline is energised or live.

The size of an exclusion zone depends on the voltage of the powerline, the type of work being done, and the qualifications of people involved.

Generally, exclusion zones are:

  • 3 metres for voltages up to 132kV
  • 6 metres for voltages up to 330kV

Note: These distances can be reduced if a worker is approved as an Authorised Person. Find out how to become an Authorised Person.

IMPORTANT: If you have to enter an exclusion zone, contact us to request written Safety Advice. You can’t enter the zone until you have that advice.

Look up and Live map

Our Look up and Live map helps you locate overhead powerlines using an interactive geospatial map. It also gives you:

  • safety guidelines and advice, including powerline exclusion zones
  • options for planning or performing work e.g. powerline visual indicators
  • information on de-energisation or relocation of powerlines
  • high load forms
  • Dial Before You Dig enquiry details.

Note: You can also download this map as the Look up and Live app.

You can scroll down to any part of the map or just type in where you want to go to. Once on site you can click and get all the property details.  You can also then find out what voltages the powerlines are at. This one in particular was eleven thousand volts, and some low voltage there as well.

If you need more information now, and you want to get safety advice, it will then take you to the powerline owner. In this case, Ergon Energy’s website.  You can fill out the form and complete the safety advice.

Also, if you want to do a Dial Before You Dig enquiry, click on Dial Before You Dig.  It will take you the Dial Before You Dig enquiry page.

If you would now like to print out your plan of your construction site, you can write in what your construction site is.  Press print.  Then you will have a powerline safety plan giving you the scale, and legend, showing you there’s low voltage network.  There are also high voltage powerlines there.  And it will give you the exclusion zones around those powerlines to work safely.

Electrical safety laws

Several laws apply when you work with or around powerlines. They’re designed to prevent people and property from being harmed or damaged by electricity. These include:

  • Electrical Safety Act 2002
  • Electrical Safety Regulation 2013
  • Work Health and Safety Act 2011
  • Work Health and Safety Regulation 2011
  • Codes of Practice approved under the above-mentioned Acts.

If you are an employer, getting to know these laws will help you understand your obligations. It’s your responsibility to keep your workers safe.

How to comply

Use the Electrical Safety Code of Practice 2020 - Working near overhead and underground electric lines for practical advice to help you apply the laws in your place of work. It outlines a process for:

  • identifying hazards
  • assessing the risks associated with these hazards
  • implementing and maintaining risk control measures
  • reviewing risk control measures.

Read more about these in the accordions below.

Identifying hazards

Before you work near electricity, you should take some time to identify electrical hazards. Plan ahead and check the location of powerlines with our Look up and Live map, which you can also download from app stores.

The following are examples of activities that can pose a risk when done near powerlines.

Overhead powerlines

  • operating machinery such as cranes, tip trucks, cane harvesters, elevated work platforms, fork lifts, grain augers, excavators and irrigators
  • putting up advertising signs or billboards
  • building work, scaffolding or demolition
  • pruning or felling trees or vegetation
  • painting fascia, replacing roofing, guttering or external cladding near service line point of attachment to a building
  • dam construction or levee bank earthworks.

Underground powerlines

  • digging and excavating
  • sawing
  • trenching
  • under boring
  • sinking boreholes
  • earth works
  • laying cables and pipes
  • driving implements into the ground such as star pickets and fence posts.

Assessing risks

If you’re carrying out hazardous activities, assess how likely it is that:

  • a worker will be injured
  • property, plant or equipment will be damaged
  • you’ll come within an unsafe distance of an electric line.

Refer to the Electrical Safety Code of Practice 2020 - Working near overhead and underground powerlines for more detail about how to assess risks.

Implementing control measures

Ideally, you should eliminate the risks associated with working near powerlines. If you can’t eliminate risks completely, you need to at least minimise them. Control measures, in order of effectiveness, include:

  • De-energising the overhead network
  • Relocating the overhead network
  • De-energising the underground network
  • Relocating the underground network
  • placing physical barriers to stop entry to exclusion zones
  • using powerline visual indicators e.g. rota markers
  • appointing a safety observer
  • delineating and setting up a safety observer area.

If you’re working or operating plant near any overhead or underground electric lines, you should also refer to the Electricity Entity Requirements: Working Near Overhead and Underground Electric Lines, (PDF 765.3 kb)
