Your Occupational Safety and Health (OSH) requirements

Work near energised electrical installations and powerlines, whether underground or overhead, is high risk work. A person in control of the work area must ensure that no person, plant or material enters the “Danger Zone” of an overhead powerline or other electrical network assets.

The “Danger Zone” is set out in Western Australian Occupational Safety and Health Regulations 1996 – Specifically Reg 3.64.

Any information provided to you by Western Power should not be used in isolation and we recommend that you refer to the Occupational Safety and Health Act 1984 and Occupational Safety and Health Regulations 1996. These documents outline WorkSafe WA requirements for working near electricity.

For queries relating to these requirements, visit www.worksafe.wa.gov.au or contact WorkSafe on 1300 307 877. Breaches should also be reported directly to WorkSafe.

Danger Zone

The size of the danger zone depends on the voltage of the powerlines

A danger zone is a specific area surrounding live electrical apparatus that ordinary persons, equipment and materials must not enter. The size of the danger zone is determined by the voltage of the electrical apparatus.

Within the Occupational Safety and Health Regulations 1996 reg 3.64, a danger zone means anywhere that:

  • is within 0.5 metres of a live insulated overhead power line or aerial bundled conductor line of a voltage of not more than 1,000 volts;
  • is within 1.0 metre of a live uninsulated overhead power line of a voltage of not more than 1,000 volts;
  • is within 3.0 metres of a live overhead power line whether insulated or not, of a voltage exceeding 1,000 volts but not more than 33,000 volts; or
  • is within 6.0 metres of a live overhead power line whether insulated or not, of a voltage exceeding 33,000 volts

Getting advice on how to work safely around Western Power’s electricity network

To ensure it is safe for you to work near Western Power’s electricity network you should consult the Local Government, the Planning Authority, Architect, Civil, Structural or Electrical Engineer or Project Manager specific to your project. Western Power strongly recommends that you also engage a qualified service provider before you start.

Request for information about Western Power’s electrical assets

Before commencing any work it is essential to complete a Dial Before You Dig enquiry to obtain the location and voltage of any overhead and underground assets.

Complete a Dial Before You Dig enquiry by visiting www.1100.com.au, downloading the 1100 mobile app or calling 1100.

Request for Tiger Tails - distribution assets

Once you have received the Dial Before You Dig information, or if you already know the asset details, it may be determined that you require the installation of Tiger Tails. Tiger Tails are a black and yellow cover that wrap around the wires. They work as a visual deterrent only and do not provide insulation.

The cost to install and remove covers on one bay of low voltage mains directly adjacent to a work site is based on the following requirements:

  • all four wires being covered
  • a minimum of one week's notice
  • mobilisation of crew and equipment
  • administrative costs
  • traffic management

Allow a minimum of one month notice from receipt of monies paid to schedule into our works program.

To submit a request for Tiger Tails, complete the following form: Request for installation of aerial visual covers (Tiger Tails) (PDF 596 kb)

You can extend the period of Tiger Tail supply by notification via e-mail. Further charges will apply.

Note: Tiger tails are visual indicators only and must not be relied upon for insulation and do not reduce the “Danger Zone”.
