I'm always amused when factories that do welding and other metal fabrication don't allow smoking on the production floor due to "health concerns" as if the smoke from the process couldn't possibly be harmful in itself.
I know, doesn't make sense. I heard a commercial recently that said over 10 thousand people a year are rushed to hospitals because of second hand smoke.
That's one of the most redicules things I have ever heard.
"Rampart, we're on our way to Mercy Hospital with a second hand smoke victim, vital signs are.....".
