Well my wife worked on a hospital some years ago:
A girl came in.
She had walked the dog.
Using that type of long leash with a spring inside and a knob on that stops the rope on outgoing.
Well this leash broke on the chain at the end by the dog.
The spring pulled the rope back.
The end then made a loop, hit her right in the eye. The end contained half of that hook u apply to the dog. Not so heavy, but still.
Eye got totaly exploded, nothing left.
Blind on one eye, after walking the dog.
A truckdriver in the firm i worked for some years ago where unlucky.
On the lowbed trailer they got a tag on axle.
This axle can be folded up back on the trailer while not in use.
On the underside is a couple of bolts that locks it in place.
He had problems with getting theese bolts out, so he used a steel bar hammering the bolts in to the middle of the trailer.
Bolts mowed, the steel bar got in between the steel plates, that started acting like a siccor.
Steel bar then comes straight up. in the speed of lightning.
He got hit by the end on his chin.
Lost all teeth on that side, chinbone, right eye and part of the scull.
Spent months on hospital untill he recovered, blind on one eye.
Turned out he had forgotten to let the air out of the airbags on the tag axle.
20 000 lbs of lifting power on that axle, pressing on the locking pins.....
Makes the locking bolts real difficult to move.:eek2
