Abstract: On December 4, 2006, Employee #1 was working for the general contractor J.C. Paredes Drywall, which is engaged in the business of drywall installation for new residential construction. Employee #1 had been employed with J.C. Paredes for four months and had worked only at the accident site since being hired. He was constructing a temporary work platform in an elevator shaft. He and a coworker had previously installed drywall at the third floor level of the three-story multi-unit apartment building's elevator shaft and had worked from a similar temporary platform that had been constructed in the same manner. Employee #1 was in the elevator shaft and the coworker in the hallway. They had completed installing several 4-by-4 joists across the elevator shaft opening and a 4-foot by 8-foot sheet of plywood on the joists, when Employee #1 fell down to the basement level. He was not wearing fall protection, and he was not using fall restraint or a positioning system. He fell in excess of 7.5 feet and sustained a fractured femur and multiple contusions. He was hospitalized.
