Well there was uh... one time where the valve got stuck on full blast, and the emergency release valve got locked up too... I don't think I could tell you exactly how big I got, since most of my vision was taken up by suit... As for how it was dealt with, uhm,, I tried to call for someone to shut the air off but, I think everyone was a bit too preoccupied uh, placing bets on "just how big it'll get before it pops"...
Suffice to say they took me to get a new suit afterward ._.
