Electrical safety & lock-out/tag-out

Isolate, lock, tag and prove dead before anyone touches electrical gear.

Key points

  • Work on equipment dead, not live. Isolate it, lock it, tag it and prove it dead.
  • In Singapore, only a Licensed Electrical Worker may repair or maintain electrical installations.
  • The occupier must set up lock-out procedures and brief every worker before maintenance starts.
  • Use RCD-protected supply, keep cables off wet ground and pull damaged tools out of use.
