I am a mentor for FRC team 3799 on Sat. 2/26 we had a serious situation occur while pressurizing our Clipper PVC air cylinders. Please read the below letter written by our program leader to our Regional Director.
Glen,
During robot testing today we had a catastrophic failure of two of the new Clippard Air Tanks simultaneously. Luckily no one was seriously hurt. We had them pressurized to approx. 110 psi and during leak checking they blew apart into small shards (see photo). I sent a note to Andy Mark (the supplier we purchased them from) earlier today. If there is someone at FIRST that should be aware of this potential safety issue please forward this to them. We were excited about using the new lightweight tanks but as a result of this have now decided to convert to an aluminum tank.

We don't really know what caused this but we just want to make sure everyone is aware of this and are taking all proper safety cautions while testing and using.
