An employee had been conducting framing work. The employee was laying plywood to a window opening and was leaning against the guardrail. The guardrail gave way and he fell from the third floor. He struck a beam on the second floor and landed between two concrete platforms in the grass. The employee sustained multiple injuries including a compressed fracture with retropulsion at the L2 vertebra, a pelvic fracture, and a non-displaced sacral alar fracture.
