Abstract: At 12:30 p.m. on September 14, 2017, Employee #1 and coworkers, journeyman iron workers employed by a construction company, were engaged in steel erection at a multiemployer construction project, a new aquatic center at a college. They were erecting the steel frames for bleachers. The frames were steel square stock and angle iron. The frames were bundled and strapped five to six together, then transported to the work area on a cart, stored on the cart, and ready to be laid out and installed. The frames on a cart toppled off, falling and striking Employee #1's leg. Emergency services were called, and Employee #1 was transported to the hospital, admitted, and treated for fractures of the right leg's fibula and tibia bones.
