Abstract: At approximately 11:00 a.m. on October 10, 2001, Employee #1, a concrete mason, was working as part of a crew that was removing the concrete forms from inside a box culvert. The forms were 8-ft by 2-ft steel frames with 1-in. plywood sheeting. The ceiling area had bowed down in an area pinching the forms. To remove the forms the crew was using two cables come-along to pull the bottoms out while placing pressure on one of the come-along the hook attached to the form came loose and snapped back strike Employee #1 in the face. Employee #1 suffered a broken cheekbone and was hospitalized overnight.
