DENVER (AP) — Regulators have proposed fining MillerCoors $128,500 over alleged safety violations at its brewery in Golden.

The Occupational Safety and Health Administration said Monday a maintenance electrician who was missing for several hours was found dead outside an open, energized electrical panel Feb. 2, and two others were burned by an electrical arc flash April 9.

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.

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.

A MillerCoors spokesman didn't immediately return a phone message seeking comment.

MillerCoors received the citations Friday and has 15 business days to contest the findings, Healy said.

"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."
