Working safely around the network

Highload permits

If you are driving a vehicle with a high load of materials or transporting large plant items, the risk of hitting overhead powerlines while in transit is real and needs to be managed.

Authority to travel for oversized vehicles

Loads over 4.6 metres require a permit to travel through the Ausgrid network area. Any person or company transporting a high load (in excess of 5m high) in the Ausgrid network area must comply with SafeWork NSW - Work Near Overhead Powerlines Code of Practice 2006.

  • when transporting high loads, plan safe travel paths that allow you to maintain the required clearances
  • before entering a worksite or property, contact the site manager or property owner for information on the approved safe travel path on site
  • visually check all powerlines if you must pass beneath them and ensure you don’t vary from the approved safe travel path

High load safety

If a vehicle does contact overhead powerlines it will become 'live' and the electricity will attempt to pass through it to the ground. 

In order to stay safe you should:

  • call 000 and Ausgrid Fault and Emergency Line on 13 13 88 immediately
  • always remain in the vehicle
  • never approach, attempt to rescue or allow others to approach any machinery or vehicles in contact with power lines
  • stay a minimum of 8 metres from the vehicle (about a bus length away)
  • treat all power lines as if they are 'live'
  • after the emergency is over and you are able to access the vehicle, get a professional to check all tyres, bearings and brakes before you operate or drive it.
