An employee was performing a visual inspection of the pulley cables in the penthouse above sterilization. The employee used a paper towel to assist in checking for burrs and defects in the cable by folding and positioning the paper towel around the three cables of the pulley system. The paper towel caught on the cable, pulling the employee's right hand into the pulley and causing a partial amputation of the little finger (distal phalange) and an avulsion injury to the ring finger.
