>Finally, someone with actual experience and knowledge has spoken up and stated the honest, real facts.
Mr. T, I don't know whose post is more irresponsible, Steven N's or your post in support.
The real "facts": PVC pipe is not approved by OSHA or anyone else for compressed air. Here's directly from OSHA:
"Since PVC material does not possess shatter resistant property, and since it is very clear from the industry's recognized practice that PVC pipes are prohibited for above ground transportation of compressed air and gases (unless the pipelines are encased in shatter resistant material), any such use by the employers, where employees may be exposed to hazards, will be in violation of Section 5(a)(1) of the OSH Act. Therefore, employers who are found to violate the above described conditions or manufacturer's recommendations, during an OSHA inspection, shall be issued a 5(a)(1) citation."
Just because thousands of cheapskates use PVC pipe for compressed air and get away with it doesn't make it a good idea.
