Working on live circuits requires a live-work permit system.

A live-work permit should, at least, contain this information:

  • a description of the circuit and equipment to be worked on and the location,
  • explanation why the work must be done "live"
  • date and time covered by the permit
  • a description of the safe work practices to be used
  • results of shock hazard analysis and determination of shock protection boundaries
  • results of flash hazard analysis and determination of the flash protection boundary
  • PPE needed to safely perform the job
  • who will do the work and how will unqualified persons be kept away
  • evidence of completion of job briefing, including discussion of job-specific hazards
  • energized-work approval signatures (authorizing or approving management, safety officer, owner, etc.)
