Abstract: On August 5, 2002, Employee #1, the assistant chief engineer for a warehouse, was on the 25-ft-high maintenance runway of an elevated section of the Matthews powered conveyor system. He was standing on a portable ladder, adjusting and tracking the break belt while the conveyor was running between 90 ft and 120 ft per minute. Employee #1 was using his left hand to manipulate a roller when his hand slipped and became caught in the pinch point between the belt and roller. The moving, rough-top conveyor belt ground off the skin and flesh from the knuckles of his hand, and ground away the skin, flesh, and nails from his index, middle, and fourth fingers. Employee #1 was transported to a medical center for treatment. The investigation revealed he was not using an extension tool or other means to move the rollers while adjusting the conveyor belt as required.
