The failure mode of plastic tanks is a catastrophic release of high pressure air that quickly accelerates large sharp plastic pieces. These pieces, with the pressure FIRST allows, could shoot more than 100 feet (IE: into the crowd).
I have been close to a plastic (non-first) 1 liter volume that failed at 100 PSI. I can tell you I am lucky to be here (the volume blew out away from me).
The only way I'll have plastic pneumatic volumes on my teams robots is if it is completely enclosed in a box (to absorb as much of the energy as possible) and even with this setup, I would be reluctant to do so.
