I hear the eye surgeons are kept in a job by bungee cord/hockey straps and people using wire brushes the wrong way and flicking loose wires into the eyeball.

That reminds me of a story my gang leader (or leading hand if you prefer,) on a building site told me several years ago.
Some years earlier he was working with another chippy on a major commercial building, when his hammer holster on his tool belt failed due to the 3/16 rivet giving way. He obtained another pop rivet and a 3/16 washer, and proceeded to re-affix the wire loop on the belt. IIRC he didn't bother to remove the belt, but in any case, he was applying considerable pressure to the pop rivet pliers handles, when the stem finally let go. Unfortunately for him, that same extensible feature of the male anatomy, with the sensitive tip, found itself jammed between the handles as they snapped shut.
He said, and I am inclined to believe him that the pain was instantaneous and intense. The blood quickly soaked through his trousers and bib & brace overalls, and he headed for the toilets to survey the damage. After about 40 minutes, he had managed to staunch the flow of blood, and staggered back to the job, where all his workmates were still rolling around laughing.
Well you might think that it could only get better from there, but you would be wrong. He was pretty uncomfortable, but made it through to lunch which provided a welcome respite. He had his sandwiches, and a piece of cake, all washed down with a mug of coffee, and was almost feeling human again. On the way back to work, he called in to the toilets for a quick pee, and that is when everything went pear shaped. As he stood before the urinal, there was no flow, but his bladder was crying out for relief. The blood had clotted around his wound, but it had sealed the pipework shut, and he had to break the scab so that normal operations could continue. That happened once more that day before he took himself off to the local casualty department, where they sorted him out with a stent. He had tears from the pain and his mates had tears from laughter, so all I can say is, be very careful when applying considerable force to pliers of any sort, Keep the handles well away from your lap.

We banned bungee cords off of the ship for just that reason. Ratchet straps are more secure and safer.
WRT angle grinders, those thin 1mm cutoff disks do a great job on flesh as well as steel. I've got a lovely scar right on top of the tendons controlling my right thumb. Fortunately after cutting through the gloves there wasn't sufficient power left to go too deeply into me so the tendons were fine - had to wiggle the thumb a few times just to confirm it though. Cutting steel reinforcing struts free overhead while holding the grinder in 1 hand isn't a good idea even if it's 'only' a 125mm model. The big 235mm one would have been safer as I treat that one with great respect....

As you would know, some 125 mm grinders have motors in excess of 1400 Watts these days, more than many old and not so old 7'' grinders, and being very much lighter, they could be out of your control even more quickly. As someone who is pretty switched on, you found that day at some cost, that all tools and particularly power tools deserve our utmost respect. How would a young, bullet proof, rip sh*t or bust type, of about 19 years, without the experience of us old blokes, go in the same circumstances, particularly if he was not too bright and alert to the risks he was taking.

Probably the same as the old blokes when they were younger.

About 14 years ago I did a shipyard safety induction course so I could work as an electronics contractor on a refit project. The ships used aluminium which developed fatigue cracks along welds over the years. The welds had to be cut/gouged out with a 125mm angle grinder fitted with a 125mm tungsten carbide saw blade.
These were known as "Meat Axes" in the trade, the original blade had positive rake and would dig in, they quickly switched to negative rake blades......anyway they passed around photos of what one of these blades did to a gloved hand that got wrapped around it. The grinders also had the lock button removed so they could not be jammed on either.

I caught my shirt on fire this morning, I was stirring a pot of Bechamel sauce and must of got too close, have to go to Fiji to get another one!
Talking about the extendable part of the anatomy, years ago when i was a spud grower we had itinerant workers to help with picking and grading, at lunchtime the wife and I would go into the house for our lunch leaving everyone else in the shed for theirs, they had a kettle and all the gear.
The kettle used to be put on top of the grading table on a flat surface,plugged in and boiled which was fine. Then along came Shane who thought it would be a good idea to plug it in and sit the kettle on the walkway,balancing the kettle with the power cord! Shane wore trackpants by the way, with no undies,reckoned he could work better without the restriction.
Anyway the kettle boiled,Shane unplugged it without grabbing the handle and poured boiling water all over aforementioned extendable part of the anatomy. We heard the screams from the house, he put cold water on it and we all got back to work at his request. Of course the jokes started at Shanes expense, until he got a bit upset and dropped his trackpants to show us the damage!He went to the doctor a couple of days later and had a week off, I don't think he could find anyone to rub cream on it.

Basic chemistry and not tidying up
You know how you always mean to be tidier and sweep up after yourself? Well, when you only manage to find time late at night to do things, such as cutting steel using the drop saw, you do tend to regard bed as a higher priority than all those iron filings sitting on the bench and under the drop saw.
When you eventually find some more time, a week or two later, said iron filings will have rusted. Your new job of chopping an old oxygen cylinder in two again takes priority over tidying up. Oxygen cylinders are aluminium, so lots of finely ground aluminium builds up beneath the drop saw. And sparks. Lots of them. Which all of a sudden become VERY bright.
Then you remember you high school chemisty - powdered iron oxide + powdered aluminium = thermite
Thankfully the mix was obviously far from ideal (probably just a fine layer at the top) as it looks like only a tiny bit of it burned, but even that tiny bit was very impressive. I have, of course, now tidied up. That's not to say I've put the rubbish in the bin, oh no, iron filings in one jar, aluminium powder in another, to be disposed of "carefully" at a later date. I may have another post to add to this thread some time soon

What did I learn today?
On a completely different track, my son has restored a 1964 Mini 850. The little plastic bits that hold the chrome "Morris 850" decal in the boot were missing. He ordered some this morning and found out that they are called "Mouse condoms"
