On 6/01/2022, an employee was walking to lunch, crossing over rebar that was bent flat to prevent impalement. The employee tripped on the rebar and fell. In front of him was a window leave out for a tilt wall concrete panel (in casting position on the ground). With the window opening, the concrete is finished with rounded edges. The employee impacted the rounded edge with his left upper thigh and hip area and sustained a fractured femur requiring hospitalization and surgery.
