The injured employee was stripping concrete forms from jersey barriers in the crane staging area. An overhead crane (crane 1) had the form lifted up just enough to take the weight off it so the concrete could cure. Another employee was operating a mobile crane (crane 2) to move concrete forms into place in the staging area. Crane 2 bumped into crane 1 moving crane 1 slightly out of place. This caused the concrete form to fall over and knock the jersey barrier over onto the injured employee. The employee was hospitalized for fractured vertebrae in the back and a lacerated kidney.
