if the medical gas lines need to be bonded why doesn't anyone carry a clamp that will fit onto the small copper med gas lines

Re: Med gas bonding
the medical gas lines in a health care facility just like the copper cold water pipe are required to be bonded but unlike the cold water pipe which is anywhere form a half inch pipe up the medical gas lines are only quarter inch or three eighth inch and I can not find a clamp to fit that small of pipe

Re: Med gas bonding
Being that the Med Gas piping is silver soldered through out, (not that that really matters) bonding it at any manifold will cover pipe reduction downstream.
The Ground jack requirements for flexible connections are not a concern now that flammable anesthesia is a thing of the past in most modern countries.

Re: Med gas bonding
Sarge, the typical split grounding water-pipe clamp can be used on smaller pipe by unscrewing both bolts and turning the back half over.
They'll easily grip as small as a #4 solid wire, so a 1/4" id tube should be no problem. I'd suggest attaching at a fitting to avoid crushing the tube.

Thank you I never thought of that sometime the solution is so simple and obvious that it eludes you

Re: Med gas bonding
Roger, is there a 517 requirement that address this, or is it simply a 250.104 issue? It seems to me that medical gas piping would probably not be "likely to become energized" and therefore no bonding would be required at all. Am I missing something?
EDIT
Or perhaps an NFPA 99 issue?

Re: Med gas bonding
Good morning Ryan. It is basically a 250.104 issue. There is the possibility that an associated Vacuum Pump or Compressor could energize the systems.
2002 NFPA 99 4.3.3.1.1.2 and 4.3.3.1.1.3 specifically excludes grounding of small and large conductive surfaces not likely to become energized in patient care areas.
I know you personally know Gaylen Rogers so you may find This Article interesting.

Re: Med gas bonding
Thanks Roger, I'll take a look at it. I do know Gaylen quite well. In fact, he retired not more than a month ago from the State of Utah.
I am going to be taking a class from someone you probably know personally (Mark Ode) here next week about 517 and the NFPA 99. I am looking forward to it, since 517 is probably my worst article of the code.
Speaking of this article and it's concept (517.13), I had to turn someone down for roughing inthe dentist chair in PVC the other day...
