Yup, this is very sad, and an eye-opener to all of us to be careful. Not a lot of people look at it as potentially dangerous, so they just throw around the weight without worrying about what could happen if something goes wrong. I'm not assuming this guy did, as it was obviously an accident, I'm just speaking in general terms.
We're in high risk doing anything, any day though. Just have to be careful. These things happen. My thoughts are with him and his family.
