The danger is that it shatters upon failure. There are types of plastic pipe rated for compressed gas use but I do not think the standard PVC pipe should be used for compressed air. |
I suspect that with the inclusion of plasticizers, a PVC pipe could be produced that did not exhibit this failure behaviour.
It's an overreach to take the position that "PVC pipe shall not be used as a means of transporting compressed air" without qualifying the pipe's composition, manufacturing process, installation and operating conditions. Despite their strongly-worded statements, I hope that OSHA is recognizing competent engineering as the appropriate way to circumvent their prohibition.
