The blood is where the severed arm landed. They didn't say whether the previous owner of the arm was alive or dead, but the implication is that he lived.cdreamer:OMG!! Don't know if that was narrated, I don't have sound, but I hope whoever was servicing that is OK. That is alot of blood.
This is the same cylinter that's in many onboard oxygen kits.JC Franklin:it was a home health O2 tank. You have got to hear the narration. Holy cow.
crpntr133:I agree with Rick about the lubricant. If I was to make a bet it would be that there was something either on the vise or the workers hand that caused it. Maybe even the wrench.
Don't think so. The point of ignition was inside the tank on the threads between the valve and the tank neck. You can see the vaporization of the tank neck threads and the valve end that was in the tank. These are the things that burned with explosive speed and caused the explosion. Whether there was some incompatible lubricant on the threads to help with ignition or not I doubt we'll ever know, but the heat came from the mechanical friction of turning the valve with great force (big wrench and chain vice) with the valve under pressure and in contact with pure oxygen - guaranteed BOOM! There's no way an externally applied lubricant could have gotten to the point of ignition with pressure in the tank.mikerault:Let's see...soak this thing down with WD40 and that should loosen it up....
