Event description
Employee crushed and killed by concrete wall panel
Investigation abstract
Employee #1 was a member of a crew that was erecting tilt-up wall panels around beam for a complete vertical lift, but they were not padded. While the second p anel was suspended in preparation for being set, it tilted in the sling and slid slightly. The panel cut through one sling and partially through the other. The erection crew scattered as it dropped. Employee #1 stopped momentarily to look b ack as he fled the building. As he did so the upper edge of a previously set pan el, which had been dislodged when the falling panel demolished its knee (pipe) b races, fell on him. He was crushed and killed. the perimeter of the slab floor of a one-story warehouse. They were using the pr escribed rigging, hardware, and methods, including the installation of adjustabl e pipe braces between the erected wall slabs and the concrete slab floor, pendin g joint completion and roof installation. As the crew neared the end of the job, they found that three slab panels could not be installed by the established til t-up method. They had to be hoisted and set in a continuously vertical position with the bottom elevated about 12 ft. Synthetic (nylon) web slings in a basket h itch were used to set one panel. The slings were evenly spaced under the lifting
