Abstract: At approximately 7:50 a.m. on February 13, 2002, Employee #1 was cleaning the build-up on Line B of the Laminator machine. Employee #1 unscrewed the screw holding guard to the exit pull roll assembly. This allowed an opening of 12 in. by 18 in. to the pull roll assembly. Employee #1 reached in approximately 20 in. to wipe the surface of the roofing material, and his gloved left hand was pulled into the nip point of the upper and lower rolls. Employee #1's thumb sustained an abrasive burn. A coworker heard Employee #1 yell, and the coworker pushed the emergency stop switch. Employee #1 removed his hand from the machine. Employee #1 was hospitalized.
