OSHA investigators in the fatal accident found inadequate safety measures for electrical hazards, but coroner's officials couldn't determine if that led to the death, said John Healy, OSHA's area director in Englewood.
"We found dangerous conditions that existed at MillerCoors in the area of electrical work," Healy said. "The company does need to take necessary steps to mitigate workplace threats to ensure the safety of the work force."
OSHA cited MillerCoors LLC for 10 alleged violations of rules for electrical hazards.
That included one alleged willful violation over allegations that MillerCoors failed to ensure employees used proper protective equipment when working near energized electrical parts. OSHA also alleged nine serious violations over work practices and protective equipment.
"We take safety very seriously at MillerCoors and regard a safe and healthy workplace as integral to our company's success," the brewer said in a written statement. "Throughout their entire investigation, we have cooperated with the Department of Labor's Occupational Safety and Health Administration, and we will continue to work with the agency to respond to the findings in the citation."
MillerCoors received the citations and has 15 business days to contest the findings, Healy said. MillerCoors spokesman Julian Green declined to say whether the company would appeal.
