well if its for pain inflicted on myself i would say the worst was when i was working in a construction waste recycling facility,the large bailer was jamed with a piece of extruded aluminum,so i climbed inside of it to unjam it with a large 25lb prybar, well it slipped as i had all my wieght on it and got hit right in my right eye, this happened while on nightshift with just a skeleton crew on,and no one heard me yelling and i coulnt see for all the blood in my eyes so had to climb out of the baler on my own .. doctor told me i was lucky i didnt lose my eye.
At the same place though,another accident while i was working on the picking line a 18yr old kid got his arm caught in a roller of teh conveyor and tore his arm off at the shoulder
And another accident at the same workplace,my buddy cory and i were working at the hammer mill (for grinding wood) and a piece of 30mm rebar went into teh hamemrmill and shot out like a rocket hitting him in the head, i thought he was dead as he dropped like a sack of hammers. He was off work with a serious concussion for a year.
some pics for those tht dont knwo wht the machinery im speaking of is
