Abstract: At 5:00 p.m. on October 8, 2021, an employee was repositioning a marble slab on an A-frame at a granite mining and quarrying facility. The employee pried the 1000 lb marble slab off the A-frame to fit a clamp on it, but the clamp did not seat completely would not secure. The employee tried to move the slab out further to fit the clamp when he felt the slab move forward and start to fall. When the employee tried to move out of the way of the falling slab, he was only above to move enough that only the left side of his chest was struck. The employee fell to the ground, and his coworkers called 9-1-1 and stayed with him until emergency services arrived and transported him to the hospital. The employee was hospitalized for treatment of four fractured ribs and punctures to both sides of the lungs.
