Personal Safety is a far more 'local' endeavor than versions administered by departments, agencies, etc. Not hazards like those of chemicals, loose electricals, etc that can transpire hidden from view.
When inspectors [often without physical background in a trade] make judgements; tainted by their own apprehensions more than what I might call probability.

I'm usually comfortable working mill/ lathe/ drill without safety glasses. One single occasion with a lathe, roughing journals on 6" Ø 4130 very heavily, threw perfect wide blue chips, a fairly consistent arc landing 6-8 feet away. Put on good wrap-around safety glasses. A few would deflect, projecting them wildly.
Caught one between left eyelid and brow. Sizzled a few seconds. Ouch.
Instead of bouncing off and being little more than an irritation, lens & frame HELD IT IN PLACE. I knocked glasses off, cool water released the chip easily.
Oh thanks, Mr. Administrative Oversight and concern of increased insurance premiums. I should have saved the chip, bronzed for display in your cubicle.

I self treated first aid; eye cup+boric acid. Part of being a 2X veteran [45+ years machining, 26 USN] our tendency to remain cool-calm-collected.
You haven't lived until crusty pus of seared skin takes 10-12 days to clear itself up. Kept it clean, washing it frequently. No scar, no impact on vision.
And no more prescription 'safety' glasses.

to Philip, from the Great Pacific NorthWET. Lol. I spent time stationed in your North Wet; calling it "World's Biggest Carwash". Had until then never seen such deluges, even here in the Midwest rarely in that scale.
For those unfamiliar with Cascade Peninsula, its rightly called a rain forest. Quite different than what's close by to their east!
