Exclusion zones

Contact with overhead or underground electric lines can have deadly consequences.

Exclusion zones are the minimum safe distance from live power lines to reduce the risk of an electric shock.

Working near powerlines can be fatal. Touching them or straying into the exclusion zone around them can result in a serious electric shock.

If you must work near powerlines, you should follow these steps:

  1. Develop a safe system of work before you start
    • Develop a safe system that ensures a safe distance from powerlines is maintained (stay outside the exclusion zone)
    • Identify overhead and underground powerlines by consulting maps and/or talking to the property owner and electrical entity. For Ergon Energy and Energex visit for your free powerline safety plan.
    • Conduct a site specific risk assessment – think about:
      • the type of plant and equipment/tools used
      • site and weather conditions
      • type of work being done
      • set-up and pack-up procedures.
    • Put risk controls in place – the most effective way of controlling the risk is to de-energise the line for the duration of work where there is a risk of contact.
  2. Keep your workers and contractors informed about electrical safety
    • Induct and train your workers and contractors in safe work procedures, emergency procedures, and exclusion zones (Figure 1).
    • Carefully plan the tasks to be completed near powerlines and work away from them whenever possible, not underneath them.
    • Show your workers the safe distance from a powerline by marking it on the ground.
    • Ensure people are aware that powerlines sag or sway in hot or windy weather (Figure 2).
  3. Avoid going into exclusion zones
    • Make powerlines and poles visible. Ask your electrical entity for permission to paint power poles and/or have them install markers or flags on the powerlines.
    • Plan your work so tree branches do not fall across powerlines.
    • Where possible, use insulated or non-conductive tools and equipment.
    • Operators should use a safety observer carrying out work near powerlines.
    • Follow the safety advice you obtain from your electrical entity.
