Pressure Test Tag Question

[Bob G]

Morning all....
  New to the trade, my employer is getting me to write the different material and length breakdown on pressure test gas.  Example 20ft Underground + 10ft Black Iron + 7ft CSST.  I was not taught this in school, I was told just to write total length of line being tested = 37ft.
Thoughts?
Thanks

I think it really depends what the inspectors in your area expect. In my area, we do the same as your employer. Lengths of different materials are all written down. Also the lengths of different sizes if it is all the same material. It's not a bad practice for someone who may be looking to add to the system.

Your school should have taught you the meaning of RTFM. With RTFM, you don't need to rely on what someone told you. In a lot of cases people are wrong. If you look at the tag requirements of 6.22.6 in your codebook and look at the list of what's required on a pressure test, it does show you need to write down the size of the piping. It does not say you have to write down the type of material in relation to those sizes, but it's just better practice since you are tagging it by saying it's safe and not leaking. In fact, I'd rather be clear about which lines I'm tagging as to not accidentally put responsibility of someone else's lines on my shoulders.

The tag is a legal document, and the more accurate information, the better, and you should be as precise as possible.  Say, for instance, there is a leak, fire, explosion, or any other serious incident involving gas, rest assured there will be an TSSA investigation.  You only want to be responsible for you own gas piping.  If your tag says 21 feet of 1/2" BI and there is 25 feet, then someone else added the other 4 feet.  If you just ball parked it and wrote down 25 feet, then you will have to try and convince the judge that you really only did 21 feet, and someone else did the last 4 feet.  I would try and be as accurate as possible, and take pictures.  It would be your best defence in a legal situation.
