Abstract: On November 1, 2013, Employee #1, a 49-year-old male carpenter with Socal Framing Inc., was engaged in the framing operations on a multi-story apartment building. At the beginning of the shift workers had used a ladder to get to the second level from the ground level. During the lunch break, Employee #1 was walking on the fully installed second floor to go down to the ground level. The walls on the second floor were completely framed in however; no drywall boards were attached at the time. The ladder, that the workers used earlier to get on the second floor had been moved, so Employee #1 attempted to use the framed wall to climb down to the ground level. While Employee #1 was climbing down, a horizontal piece of lumber, on the framed wall, gave way and he fell about 10 ft onto the concrete floor at the ground level below. Employee #1 suffered multiple fractures in the fall and was hospitalized for about a week. This employer was engaged in the framing operations for residential and commercial building construction and Employee #1 was not a contract worker.
