Well I was working in a -40 walk-in freezer and was standing on a stool to reach something and leaning against some boxes. When I pushed off to stand up straight the stool slid and I started to fall. I grabbed the corner of the evaporator and my hand slipped on the sharp edge and well you see what happened. I had to keep on with what I was doing because it was a blood plasma freezer and it was down. I couldn't stop till I got it back up and running. I should have just gone ahead and fell, it would have turned out better.
