Do Don't
  • Obtain a signed electrical permit before starting any electrical work.
  • Confirm the exact circuit and isolation points match the permit details.
  • Prove dead at the point of work using an approved voltage indicator.
  • Display the permit at the work location so it is visible to all.
  • Lock off all isolation points with personal padlocks and danger tags.
  • Cross-reference with other active permits to avoid conflicting work.
  • Return the permit to the authorised person when work is complete.
  • Stop work and contact the authorised person if the time limit expires.
  • Ensure all earths are applied before starting work where required.
  • Brief all members of the work team on the permit conditions.
  • DON'T start electrical work without a valid signed permit in place.
  • DON'T assume a circuit is dead without proving it at the point of work.
  • DON'T work on circuits not covered by your specific permit.
  • DON'T remove another person's lock or tag from an isolation point.
  • DON'T allow the permit to expire while work is still in progress.
  • DON'T re-energise circuits until the permit is formally cancelled.
  • DON'T carry out live working unless specifically authorised and controlled.
  • DON'T leave the work area without handing back the permit.
  • DON'T ignore changes in site conditions that affect the permit controls.
  • DON'T issue permits for equipment you are not authorised to control.
