Say this

  1. A confined space is any enclosed space where the air can be bad, oxygen can run low, or you can be buried. Tanks, manholes, pits, silos and pipes all count.
  2. You can't see, smell or feel low oxygen. Only the gas detector tells us the air is safe, so we test before entry and keep a detector on the team inside.
  3. No permit, no entry. The permit must be posted at the entrance and must match the job you are doing. If the job changes, stop and get the permit updated.
  4. Your name tag goes on the board at the entrance when you go in, and comes off when you come out. That is how we know who is inside.
  5. The ventilation fan stays on the whole time you are inside. If it stops, come out.
  6. If your detector alarms, you feel dizzy or something feels wrong, get out at once and tell the attendant. Don't stop to finish the job.
  7. If someone collapses inside, do not go in after them. Raise the alarm, call the rescue team and use the winch and lifeline from outside.

Ask the crew

  1. What are the three things that make a space a confined space?
  2. Who is our attendant today, and what will they do if you stop answering?
  3. Your detector alarms while you are working. What do you do?
  4. Why must you never climb in to help someone who has collapsed?

Show them

  • The posted entry permit and the gas readings written on it.
  • The name board at the entrance and how to use it.
  • The tripod, winch and harness, and how the lifeline clips on.
