Engaging a contractor for high risk work
If you’re a person conducting a business or undertaking at a workplace, you’re legally required to take reasonable steps to make sure that no person, plant or thing at the workplace comes within an unsafe distance of an underground electric powerline. You need to make sure all risks are assessed by your designer or contractor.
Work near energised electrical assets is considered high risk. Activities that can increase the risk include:
- entry into the powerline backfill below the protective cover strips, bricks or equivalent (typically installed approximately 100mm above cables)
- removal of flowable fill backfill
- excavation beneath the underground powerline.
If you’re doing any of these activities, we recommend you engage an Ergon Network rated Transmission Civil Contractor to carry out work and/or help to assess risks and develop safe work methods through our Electrical Partners Portal. There is a fee for this service.
IMPORTANT: All works need to consider the Electrical Safety Code of Practice 2020 for Working Near Overhead and Underground Electric Lines.
