Jerry L. McClelland, Contract Superintendent for Turner Industries Group LLC (Contractor ID# HPQ), age 44, was killed while installing a door on the side of a digester filtrate tank on November 18, 2014. McClelland was standing in front of the suspended door when the lifting lug broke, causing the 2,620 pound door to fall and strike him. The accident occurred due to management’s failure to ensure persons were clear of the suspended load. Management also failed to ensure the door was securely rigged before being lifted. Furthermore, management also failed to ensure that the lug and welds were not used beyond the design capacity intended by the manufacturer where such use created a hazard to persons. The door fell because the welds attaching the lug to the door stiffener were undersized for the encountered stresses. Further, the welds were irregular in shape and contained defects, such as lack of fusion, porosity, and undercutting, which adversely affected the weld’s capacity.
