copper vs pvc compressor lines?

Had a pvc line blow out in a sheet metal shop I worked at years ago, huge chunks shooting across the shop. Luckily it just scared the crap out of everyone and no one was hurt. Just because you`ve had pvc in your shop for years without incident just means you`ve been lucky! I`ll be running black pipe thruout mine, actually sitting here waiting for the propane co. to finish installing my garage heater, woohoo!!!
