At about 10:30 a.m. on June 3, 2019, an employee was on an oil rig that was being rigged down. As the rig was reaching half mast, the employee was on the rear of the rig, placing the weight bucket onto the storage hook. As he dismounted the rig, he lost his footing and his right hand was caught in a pinch point between the top and bottom sections of the derrick mast as it came down. He suffered injuries, including an amputation injury, to the index, middle, and ring fingers.
