Notes:

  1. These exclusion zones apply to any part of a person including any extension of the person such as a tool or vehicle, unless the extension of the person is an insulated device and has been tested as safe to be used on or near the live part.
  2. Any work carried out which is intended to bring a person (including any extension of the person) closer than these exclusion zones is live electrical work and must be carried in accordance with the Electrical Safety Legislation.
  3. For meaning of instructed person, authorised person and untrained person, refer to Appendix A.
