Abstract: At approximately 10:30 a.m. on September 22, 1997, Employee #1 was standing on a 27 ft square work deck, pouring the contents of a 35 lb bag into the mix in a ribbon blender. A coworker entered shortly thereafter and found Employee #1's body in the blender. He had been killed. The mixer was no longer running, but the coworker unplugged it and went for help. The blender had a plywood lid with a screen in the center through which mix additives were poured. An interlock device was supposed to stop the blades whenever the lid was raised but the mechanism was broken and it failed. There were no witnesses to the accident but it is believed that when Employee #1 raised the lid, his coveralls became caught by the rotating blades and he was pulled into the mixer.
