The family of a Kentucky man killed in a workplace incident has filed a lawsuit against his employer, GE Appliances, and other parties.

Steve Herring, who’d worked for the company for more than two decades, died in February after being pinned by machinery while working on a refrigerator-building assembly line. News sources are reporting that the state OSHA’s investigation into the fatality found that it could have been caused by an inadvertent activation of an improperly positioned gate interlock control.

The lawsuit filed in Jefferson Circuit Court last week names General Electric Company, Design Safety Engineering Inc., Doerfer Corperation, Doerfer Acquisition Company, JR Automation Technologies LLC, Haier US Appliance Solutions Inc. and Kentucky resident Mark Miller as defendants. The lawsuit claims that the assembly line Herring was working on was "unreasonably dangerous" and in "defective condition." It alleges that there were no instructions or warnings about the hazards on the line — and that the companies being sued were aware of the defects. The suit requests punitive and compensatory damages

According to Kentucky OSHA, GE made changes to the safety programming on an assembly line that was identical to the one at which Herring was pinned following a 2014 incident. However, the company didn't fix the line where Herring worked until after Herring died.

An inspection conducted by the agency after the fatality resulted in GE being cited for seven safety violations and fined $98,000. The company is appealing the fine.
