Is OSHA trying to outlaw ammunition? The NRA thinks so. As a result of the group’s objections to a proposed rule on explosives, OSHA is extending its comment period on the regulation. Speak now or forever hold your peace:

OSHA has extended the comment period on proposed changes in its explosives standard for 60 days, to Sept. 10. The amendments, published April 13, have been generating significant buzz within the gun rights community, with the National Rifle Association saying it “indiscriminately treats ammunition, powder and primers as ‘explosives.’ ”

The NRA is organizing opposition to the rule, which it believes would prohibit possessing firearms in gun stores (and other commercial facilities containing explosives); require evacuation of such facilities, “even your local Wal-Mart,” the organization says, during an electrical storm; and prohibit smoking within 50 feet of such facilities. NRA said July 9, when OSHA announced the extension, that it, the National Shooting Sports Foundation, and the Sporting Arms and Ammunition Manufacturers’ intend to file comments on the proposal “based on the severe effect these regulations (if finalized) would have on the availability of ammunition and reloading supplies to safe and responsible shooters.”

OSHA says written comments may be submitted (identified by Docket No. OSHA-2007-0032) via www.regulations.gov or faxed (10 pages or fewer) to the OSHA Docket Office at 202-693-1648.
