Abstract: At 11:19 p.m. on December 13, 2018, Employee #1 had just finished a print job that did not require perforation in the middle. The employee was attempting to change the perforation blade in Printer #86, using an open ended wrench in the POG department. The wrench became stuck on a nut that needed to be loosened. Employee #1 was going to "jog" the machine to get the wrench in a better location in order to break it free. When Employee #1 hit the ready button, the printer began to jog unexpectedly. She saw the wrench moving toward the crossbar and reached in to grab it, as to not damage the machine. At that point, her right ring finger became caught between the wrench that was rotating towards the crossbar, and the crossbar, crushing her finger. Employee #1 sustained a partial amputation to her finger.
