I could finally sit down today, so I ran my bathroom subfloor build through a mind sim, to determine at which point I had developed the laceration to my left eyeball. I thought about any operation I did that might have required eyepro, where I may have neglected, and think I found the culprit based on the nature of the injury and what I've seen from chunks of debris spalling into peoples eyes.
Thankfully it is healing, but since the only mirrors are in my car and my bathroom, and the bathroom is disassembled, I did not notice the damage until I saw it in my vanity mirror after my morning walk with my Dog the other day.
I'm such a stickler about Eye Protection too, so it figures something like this would happen to me for what was likely a few careless strokes of a hammer and chisel during the removal of the rotten sub-floor.
I was paying so much attention to safety detail too, but mostly respiratory and general exposure/possible contamination of otherwise clean areas, as there would be mold, old paint and fiberglass floating about.
I can't be certain that I was hit by spalling, but I did notice it a few times while working, and that was the day I gave my Son the Eyepro, because he was going to help me out for a bit. I have multiple pair, but I put mine on him before demonstrating what to do when you run into screws or nails, and why the prybar is the preferred method. I'm an idiot for that, but maybe someone here will remember my story and save an Eye. Mine will be fine, but it was scary, and until I determined a logical conclusion, I could not be scared or comforted, so I can only pretend it was scary, or try to remember to remember to think of it as pretty scary.
This is a guy banging metal on metal, and he specifically mentions wearing eye pro, and I had watched this video, and noted the single frame of spalling in my research. I was able to easily remember and find it when it became relevant, and it only took me 3 shots to pause the frame of spall.
Maybe something else happened to my Eye? Maybe not.
Regardless, Extra, Extra attention to Eye safety from now on, and if anyone benefits from my near miss, that's worth sharing my mistake.
Buddy of mine had a nail ricochet into his Eye. He was blind in that Eye for nearly a year, but mostly recovered, and made sure to spread the word of how important it is to protect those Eyes!
At the 1:22 mark:
Guy does not get hit by it, but you can imagine if you were.

And incase anyone thinks that that is totally not rocket related, what if you could cause a spall like that with a mechanically triggered deployment something or other?
It would certainly ignite an ejection charge or complete a relay.
I'm designing a spring loaded deployment system that is based on the JA-Ru "Swat-Shot" $1 toy that is used to swat flies.
It is just a spring loaded sear, but do to it's geometry and light weight, can be loaded onto a non L1 rocket, and activated by a pushrod.
