(60,320 posts)I wasn't trying to prove I knew more than you, just that you don't know everything and you can't imagine all failure modes. That's a big difference. I can't imagine all failure modes, but I know from experience that there are always more failure modes than even highly knowledgeable people can imagine.
Once again, you are fallaciously using the perfect to destroy the good. Just because a plastic hard hat won't stop every projectile or falling item does not mean it won't stop some. Just because items weighing hundreds of pounds are stacked or topple over or fall doesn't mean that items weighing ten pounds don't do the same things.
Since steel toe boots won't stop a ten ton block of metal falling from 30 feet, you shouldn't wear those either, by your fallacious logic.
Flying metal parts do slow down after a ricochet or two.
Regulations, such as OSHA hard hat regulations, have to be applied broadly and generally. That is the short answer as to why you had to wear hard hats under ten ton steel lifts, the question you posed in post 36, since the longer answers will never satisfy you. There is not enough time or money for government analysts to examine every plant and operation under all conditions to determine which ones can safely avoid using plastic hard hats to make it ever so slightly more convenient for some workers.
But you are so much wiser than me. You should not wear a hard hat.
I'm not as smart as you. I would wear a hard hat.
