I still say it comes down to touching a spinning shaft or not touching a spinning shaft.. vs touching a stationary shaft or not touching a stationary shaft.
thinking about it.. we are alot closer to other dangerous things than we realize.
you are usually about 2" awayfrom the average spinning drill bit, 3" away from a rotating sanding disc on an angle grinder, less than a foot away, ( 8" on at least 1 model I know ) from a rotating fluted shaft on a hand held fence post auger.
the list goes on and on and on.
I personally know 3 guys that had hands captured and crushed by using an air ratchet ( not an air impact gun.. but the actual air ratchet that had the paddle style handle ).. you squeezed the handle and the head rotated the socket. you could be in a position so that when the bolt or nut snugged up that the body of the ratchet rotated, trapping your hand against the air paddle, thus crushing it before you could react and unplug the air line, or, as in the case of one buddy, yell for help, as he had attached a 2' whip line to his gun witht he qd on the end of the whip line, and the whip line screwed into the gun.. reaching across his body with hand trapped and arm twisted a bit.. he couldn't reach the whip to unhook it. Unfortunately we were all working in a noisy factory, that, due to safety rules, had yellow tapy lines all around the assembly line areas, so no one was real close to the guy.. and due to safety requirement we were all wearing -30db ear plugs, and safety goggles that killed out perif vision... all using our own power tools.. it was some time before someone walked thru and free'd my buddy. ( water meter factory i worked at while in college back in 90 or so ).
danger is out there.. choose what portion of it you will live captivated in in fear about, respect the rest as per your threshold for personal safety.. and go about your business.
remember.. there's still that odd chance something from space or the sky will hit you...
semi truck full of logs might have brakes fail, run off the road to avoid a 4 way intersection, run down into the ditch, thru the ditch, knock down a fence, plow thru a couple parked cars in a parking lot, then hit the wooden front porch of the office portable you are working in, hitting it so hard that furniture falls over and it feels like a bomb went off. oh.. wait a minute.. that happened to ME

My office is right at the door to the portable.. just another few feet and I'd have been creamed. if there had not been 2 cars parked at the right spot in the parking lot to absorb a lil energy from the logging truck i may not be here.
so.. semi trucks are dangerous right? ban them maybee?
hmm.. that brings to mind another incedent.. was working an outside gig, sound booth tent was setup in a park location in a small city at a fair. road mad a stop and took a right angle turn to the right to go around the park area.. our tent was 25' foot from the curb.. tent adjoining our was a refreshment tent.. they touched on the sides. guy had a seizure floored his gas pedal, car carrenned down the road, hit 2 peopl ( killing 1 ), jumped the curb, and ran thru the refreshment tent, past it 10' hitting a statue in a pond before stopping. people in the refresh tent were hurt. someone at the curb jumping got ran over as well.. as i recall, they later died. I was inches or feet at the most, away from that one...
I know what you are thinking! lets ban CARS
it's a dangerous world people...
don't grab moving parts, eat yellow snow, or argue with a charging bovine...and try to be carefull about the rest...
