SHELBYVILLE – A central Indiana glass factory faces what the state workplace safety agency calls a record $453,000 in fines for violations that went uncorrected after a worker’s death nearly two years ago.

The Indiana Occupational Safety and Health Administration imposed the fines on Pilkington North America after inspectors found 29 violations at its Shelbyville plant, the Indianapolis Star and the Indianapolis Business Journal reported Thursday.

The safety allegations follow $150,000 in fines that the agency charged the Toledo-based subsidiary of Japanese conglomerate NSG last month for six repeat violations.

In September 2010, a maintenance worker was crushed to death in machinery at the plant, resulting in Pilkington being fined $15,000.

Pilkington produces glass for companies such as Honda, Toyota and GM.

The state agency said violations ranged from missing warning signs to knowingly exposing workers to dangerous machinery without proper safety guards at the factory, about 25 miles southeast of Indianapolis.

“We were very disappointed to find they hadn’t made the corrections we ordered them to make,” agency spokesman Bob Dittmer said.

Pilkington spokeswoman Roberta Steedman said the company has corrected some of the issues while it is evaluating others.

“We share a common goal with IOSHA, with the United Steelworkers and with our workforce, to provide a safe workplace for all our employees,” Steedman said. “The company will continue to work cooperatively and proactively with our employees and with IOSHA in this regard.”

State officials returned to the 350-worker factory for a comprehensive inspection because employees complained of ongoing safety problems, Dittmer said.

“We inspected everything, overturned every single rock we could lay our hands on,” he said.
