Default Any dental office experts?

I'm working on the rough plumbing for a dental office ( 12 chairs ). I have questions regarding piping for gas. Any "serious" advice would be appreciated. I'll ask my questions directly to anyone who could PM me. Thanks in advance!

I have a couple questions regarding the piping for Nitrous & Oxygen. Firstly, there are 1/2 o/d & 3/8 o/d inlets on the boxes located in the exam rooms. Also, the piping off the gas manifold is 1/2 & 3/8 o/d. Can I run my trunks in 1/2 I/d & reduce at each end of the run? Secondly, is there a specific name brand for brazing rod which I can use?

Are you licensed to do medical gas work! Second are you insured enough if there is a screw up? Make sure that no disclaimers on on your policy.

Are you really willing to put people's life at risk based on information you receive on a public plumbing forum?

I am doing Per Diem work for a friend. I have noticed items on the drawings that don't jive with how the install is planned. I've asked about the med gas certification, and was assured there was an employee med gas certified. I tend to operate on the conservative side. Lots of "what if" as well as other questions. I guess my curiosity is piqued as to how this should be done.

I'm not licensed to do med gas so I won't touch it but I have done a couple of dental offices and have seen what they do. All of their gas lines were ran in 1/2 copper and iirc reduced at the box.

Here you are not supposed to touch med gas unless you hold a journeyman med gas certification.

Get a NFPA 99 2015 addition and look it up. Don't touch any med gas work unless you hold a certification. You are not even slowed to put hangers up unless certified. Most of the time all gasses are run in 5/8 od oxy/med copper vacuum is run in PVC sometimes. Violations is code are common so don't get yourself in the middle of firestorm unless trained to know what the rules are.
