EE was changing out belt rollers. While EE and another EE had a top roller raised to install, it slipped out of EE's hand and landed on EE's right hand that was between the roller and the belt framing. This caused a laceration and a fracture to the tip of EE's ring finger on the right hand. 2 stitches were needed to close the wound and a finger splint for the tip of the finger.
