U.S. Occupational Safety and Health Administration officials cited Bayer for 13 serious and two repeat violations, following a six-month probe of the explosion and fire in the plant's methomyl unit...Bayer plant manager Nick Crosby said the company would be studying the OSHA citations and "dealing with them appropriately."
