Say this

  1. Check your tool and lead before you plug in. Look for cuts, cracks and burn marks. If you find damage, tag it and hand it in.
  2. Only the licensed electrician opens panels or repairs wiring. If something trips or sparks, stop and call the LEW.
  3. Before maintenance, the equipment gets switched off at the isolator. The stop button is not enough.
  4. Fit your own lock and your own tag. Nobody else removes your lock, and you never remove theirs.
  5. Try to start it before you touch it. If anything moves or hums, stop and report it.
  6. Keep cables off wet floors and out of walkways. Wet hands and wet ground make a small fault deadly.
  7. If someone gets a shock, cut the power first. Do not grab them. Then call 995.

Ask the crew

  1. Where is the isolator for the machine you work on?
  2. Who is allowed to remove your lock?
  3. What do you do if your extension lead has a cut in it?
  4. Someone is stuck to a live cable. What is the first thing you do?
