Abstract: On June 22, 2010, Employee #1 was contracted to perform finish carpentry work for a new home. The plans for this house included a large opening in the floor with a staircase on one side. The stair openings glass railing was not installed. The glass railing was to arrive soon and the 2 ft by 4 ft guard railing, to protect workers, was replaced with a 2-in. by 0.75-in. sticks wrapped with yellow caution tape. Employee #1 was working on a door to be hung between the garage and the interior of the house. Employee #1 was working within 5 ft of the 11.5 ft fall of the staircase. A coworker heard Employee #1 holler and turned around and saw Employee #1 fall and hit the incomplete stairway. A large cabinet was standing next to the table with the long, 93-in. side up. The cabinet fell over and hit Employee #1, who then fell over the edge of the staircase and fell 11.5 ft to the lower level. Employee #1 was not provided with any fall protection. Employee #1 suffered three compressed vertebrae fractures and a fractured pelvis and was hospitalized.
