I've heard of several people braking their carboys, but this it my first time. And I spent the afternoon in the hospital because of it. I was washing it after kegging the batch, and for no apparent reason, the bottom just fell off. I was turning it over to drain, and while my arm was under it, it broke. It cut my wrist, severing a tendon and possibly a nerve. It was half full - or half empty, depending on how you view life - and water splashed everywhere. I noticed that there was a lot of red water too. I didn't know why, until I noticed that I had a new eye on my wrist. It turned out that it wasn't an eye, but a deep cut. Blood was just pouring out. Being home alone, I decide that I'll take an ambulance ride. The doc said I'm going to need surgery to repair the tendon, and I'm not looking forward to that.
So, the moral of the story it to be very careful when cleaning glass carboys.
