OSHA is worried about lead exposure at Illinois Gun Works. The press release makes things sound almost reasonable. 2012 - 06/11/2012 - US Department of Labor's OSHA cites Illinois Gun Works for exposing workers to lead, other hazards at Elmwood Park, Ill., plant The citation (pdf) is much more interesting reading. I love the recommendations that they stop using large caliber guns, like 9 mm and .45 caliber, to train with, and that they switch to smaller caliber guns. I don't know what the law says in Illinois, but don't most states require firearm safety to be done with the actual gun you want to get a carry permit for? The recommendation to prohibit any shotguns and/or rifles firing in the firing range. (page 6) I don't usually buy into conspiracy theories, but I might make an exception if OSHA thinks that gun owners shouldn't be allowed to use anything bigger than a 22LR when they train.
