Warnings from OSHA and some state agencies, including an incident where an employee suffered a broken nose and facial cuts. Even if you are willing to take the risk, in a commercial setting it will be an OSHA violation with potential fine if there is an OSHA inspection.

everyone will poo poo the pvc idea, but i've had it in my shop for decades. Sweat copper works well also. I personally wouldn't screw (no pun intended) with the black iron. It'll rust inside and be a mess in the filters and separators.

Steve-
Just because you have used PVC for compressed air for decades and have not suffered a failure does not counter the scientific evidence that PVC is not an appropriate material for delivery of compressed air. http://www.lni.wa.gov/Safety/Basics/HazAlerts/902.asp
The fact that your PVC has not failed or caused injury is merely anecdotal.

It appears very little is of consequence to you.

Sometimes you make useful contributions to news group discussions, sometimes your ignorance knows no bounds.
This current discussion falls in the later category.
Check the date on the osha letters. Hmmmm looks like Reagan or Bush was president.
Further, if you read the notice from the private company
PLASTICS PIPE INSTITUTE 355 LEXINGTON AVENUE, NEW YORK, N.Y.10017 212-370-7341
RECOMMENDATION B THERMOPLASTIC PIPING FOR THE TRANSPORT OF COMPRESSED AIR OR OTHER COMPRESSED GASES
Adopted January 19, 1972
The Plastics Pipe Institute recommends against the use of thermoplastic pipe to transport compressed air or other compressed gases or the testing of such piping with compressed air or other compressed gases in exposed above ground locations, e.g. in exposed plant piping. It is recommended that all thermoplastic piping used to transport compressed air or other compressed gases be buried underground or encased in shatter-resistant materials. In designing thermoplastic piping to transport compressed air or other compressed gases, the strength at the operating temperature, the pressure, the energetics, and specific failure mechanism need to be evaluated.

So govt & OSHA directives hold no sway with you........looks like it started as a non-government initiative.
I guess next you'll be arguing against changes / updates to seismic design code because they're based on "pencil pusher" research & analysis?

Good for you, but I'd never take the chance. In industry, it is an OSHA violation. It has been proven to fail.

yeah well, they say (now) not to use soft copper for NG lines and hookups. But that's all we had for almost a century. Also, ALL the NG lines i pulled out of my 140 year old house were galvanized. They say don't do that either. Hmmmmm.... real world, or pencil pusher???

Yeah and a few days ago I posted an OT concern about the increasing number of labeled and unlabeled off topic posts (including troll materiel); and as expected got criticized. But the fact is, I have been hanging out and contributing to this group for 10-15 years and had it has been a good experience. But the increasing number of off topic material (excluding spam) that appears to be coming for subscribers is increasing rapidly. If it continues rec.woodworking will become a useless wasteland just like one of our RV groups and others. The increasing amount of venomous name calling also directly follows the path that ( http://groups.google.com/group/rec.outdoors.rv-travel/topics?lnk=srg ) took. When I looked at rec.outdoors,rv. travel at the time of this post there were 28 items on the subject list and one was on topic. There is also a very large amount of fighting, name calling and profanity on that site.
What this group needs to understand is that many, maybe most, of us are woodworkers who spend time working in the shop, spending time with families, etc. We do not spend large amounts of time sitting in front of the keyboard plotting filtering strategies to protect us from the crap that shows up in these groups. When using a group becomes too difficult we just quit using it.
You won't miss me but as other folks fade away, as they have with other groups, you will miss the knowledge and resources these people provide.

Unfortunate but, some pride themselves with destroying groups and Usenet by infiltrating the group and constantly raising the grain of the types with the 20 grit personalities. Sometimes this takes a few sockpuppets and that is done on a professional calibre. I have seen too many groups bite the dust this way. This group has surprisingly survived a tonne of this BS.
One has to wonder that some editorialize so well, with so much time spent here, actually do any woodworking, at all.

Yeah but maintaining the site's integrity is easy:
1 - Don't post off topic 2 - If you are compelled to post off-topic, include "OT" in your subject line.
Don't get me wrong. There is nothing wrong with occasional jokes or good-intent banter. That is what builds camaraderie among us. But when a group gets recognized as tolerant of BS, the spammers, trolls and others flock like geese.
We are on the verge of becoming a sanctuary.
