On May 24, 2010, Wilbur A. Farris, maintenance manager, age 61, was fatally injured while in a roller mill when it started. Electrical power to the roller mill had not been locked out.
The accident occurred because management failed to ensure that safe work procedures were followed while performing maintenance and mechanical work in the roller mill. Farris asked another person to lock out the roller mill for him then entered it without ensuring that the electrical circuits had been de-energized and locked out. The roller mill started while Farris was inside it.
