Rupturing tanks at 120 psi is not fun.. not in the slightest. While there have been (luckily) no serious injuries from exploding tanks, it can leave you quite shaken. The sound is nothing to sneeze at either, at GTRW many students had momentary hearing loss and ear pain that lasted into the next day just from being in close proximity of it going off, and this was in a large open area.
Correction. The old white tanks, Clippard PN AVT-PP-41, are polypropylene as well, not PVC. I am not aware of a single manufacturer that rates PVC for use in gas storage - PVC is generally only rated for liquid pressure.
