Abstract: At approximately 5:20 p.m. on December 16, 2013, Employee #1 and Coworker #1, lathers employed by a construction contractor, were working at a site where a new one-story residential building was being constructed. Employee #1 was installing wire mesh on the side wall of the building. To gain access, he was using a step ladder, Fat-Top Model FT130-04. Employee #1 fell from the ladder, a fall height of 4 feet. Coworker #1 saw Employee #1 on the ground after the fall. Employee #1 told Coworker #1 he was fine and did not require assistance. Then both workers left the work site to go home. Later that day, at approximately 6:30 p.m., Employee #1, who was home, showed signs of altered mental status. He was taken to the hospital, admitted, and treated for an intracerebral bleed secondary to an aneurysm. Employee #1 remained hospitalized for 29 days. The employer reported this event to Cal/OSHA at 10:45 a.m. on December 17, 2013. During the subsequent investigation, the investigator determined that the employer was a specialty trade contractor primarily engaged in plastering and drywall. Employee #1 had been directly employed by the company, installing lathing and other appurtenances to receive plaster, for approximately 10 months.
