Abstract: At 8:30 a.m. on August 31, 2017, Employee #1, a drywall hanger, was doing some pre-work installation in an unfinished attic. He was on his knees on top of the ceiling joists. He had secured a piece of drywall and was screwing it into the studs. As the employee was crawling to position himself to continue screwing the drywall, he placed his hand on a joist that was not secured correctly. The joist collapsed, causing Employee #1 to fall approximately nine feet to the concrete floor. The employee sustained a concussion, a laceration to his head, fractures in both wrists, and a C4 spinal fracture. He was hospitalized for his injuries.
