What OSHA “willful violations” occurred in at Tyson’s Food? Why is that that the case?

Tyson Foods Inc. has been cited by the U.S. Department of Labor’s Occupational Safety and Health Administration for four workplace safety violations at the Hutchinson prepared foods manufacturing plant after a worker’s hand was severed by an unguarded conveyor belt. “Removing guards and failing to train workers in proper lockout procedures is inexcusable,” said Judy Freeman, OSHA’s area director in Wichita. “Tyson Foods failed to ensure safety procedures, demonstrating a lack of commitment to workplace safety and health and resulting in a tragic injury.”

OSHA began its inspection upon learning of the amputation, which occurred June 17, 2013 when four workers were cleaning conveyor equipment at the end of their shift. Guarding on the conveyor was removed, exposing workers to rotating parts. A worker’s frock and the employee’s arm were then pulled into moving gears of a conveyor that had not been locked out to prevent unintentional operation. Another situation involved fall hazards at Tyson Foods plants when workers ascended upper platform work areas in two separate plant locations.

According to OSHA’s investigation this happened due to Tyson Foods not training workers on procedures and to lock out equipment use in situations such as this in order to prevent the unintentional operation of equipment and exposure to amputation hazards.

An OSHA violation is serious if death or serious physical harm could result from a hazard an employer knew or should have known existed.
