Abstract: At 11:06 a.m. on February 26, 2021, Employee #1 was with a coworker, an electrical apprentice, in the attic of Building A-1 reviewing an upcoming assignment that involved running some lines for electrical instrumentation in that location. The attic of building A-1 had several light fixtures installed into the floor of the attic workspace that provided light to the primary work area below. Employee #1 stepped on and fell through a light fixture hitting the concrete floor approximately 17 feet below. The light fixtures were not designed to support a live load, and the employer did not have any guards installed to protect employees from this hazard. The employee was hospitalized to treat a broken neck, dislocated vertebrae, spinal cord injury, loss of diaphragm capacity, and left hip fractured.
