Prohibition of guns in company parking areas. Employers in Oklahoma may also prohibit the transportation and storage of firearms inside locked vehicles parked on property owned or leased by the company under a permanent injunction issued by the U.S. District Court. The injunction prevents enforcement of a section of the Act (OK Stat. Tit. 31 Sec. 1290.22(B)) that barred such prohibitions. The October 2007 injunction states that the law that prohibited employers from banning weapons in employee vehicles conflicted with the obligations and objectives of the federal Occupational Safety and Health Act, which requires employers to control hazards in the workplace that could lead to employee death or injury.
