An employee was installing a gas shock on the lid of a large box in the dress-out area. The box requires two shocks and after installation of the first shock, another employee asked the injured employee to move the box that he was working on. The injured employee was in the process of moving the box when the lid closed and caught his hand between the lid and the box frame. The employee suffered an open left thumb distal phalanx fracture with a nailbed injury.
