My arm was crushed in a haul off machine(Motorized, counter revolving rubber belts) while working at a polyethylene pipe plant back in NJ. There was a rubber bladder between the extruder and the cooling tank and the supervisor told me to pull it through the tank and get it started. I told him the bladder was too far away from the extruder head, resulting in folds that were deeper than usual.
There was a blowout that got stuck in the bladder right when I was inches away from the haul off machine, I tried to pull it free and when I did, my hand went between the belts, pulled my arm in and started grinding away at it because they were only around an inch and a half apart. I yelled, dropped to my knees to keep my arm from breaking from the angle.
It was early in the shift and there weren't many other workers around but this little old Jamaican guy ran over and tried to use the wheel on top used to adjust the belts up and down to raise them but made it tighter instead. I pushed him away with my left hand, got myself calmed down and hit the emergency stop button. That set off an alarm that got someone else's attention and they freed my arm.
They called an ambulance which took me to the hospital to get it checked. I remember the girl posing my arm for the x-ray twisting and manipulating my arm into the right position and thinking "What the ****, you idiot?! My arm was just crushed, ya know."
I ended up just losing a huge patch of skin on bicep and walked around with my arm in a sling for a month. My bicep ached off and on for years after though.
Anyhoo, the president of the company found out I been dabbling with PCs and called to ask if I wanted to do some data entry in the office using Excel, probably so I wouldn't file a worker's comp claim. I had bills to pay and the claim process was slow as dirt in NJ back then so I said eff it, why not. Even though I had done data entry before, my arm couldn't even handle it for eight hours straight.
I had to give up after a couple of weeks and decided to use all my vacation time for the year to take a trip to Myrtle Beach and rest.
