Industrial Hard Hats Injuries

I've never actually seen anyone get hurt too bad on any of the jobs I was working at. But I've heard plenty of scary stories. Guys get hit in the head and have to get stiches, shots and antibiotics. None of that would have been necessary if they had their industrial hard hats on. I've heard of other guys who even had nails and things impaled in their skulls, had to go to the hospital, and were never able to work again. Their families really suffered, and they lost their homes. What a lousy sham. That right there is enough reason to never take off my industrial hard hat. Seriously, who needs all that?
