Electrical work on high voltage equipment

Following several high voltage isolation and access incidents, employers and electrical workers are reminded to ensure all workers involved in work performed under an Access or Test permit have signed onto the permit before work commences.

Workers must have a clear understanding of:

  • the nature of the work
  • isolation points
  • the exact areas and equipment covered by the permit.

All exposed parts must be treated as energised until they have been isolated and proven de-energised. Each high voltage exposed part must be earthed after being de-energised.

Any changes to the access coverage of the permit must be communicated to all workers.

All workers who have signed onto the permit must sign off before surrendering the permit.
