Abstract: At 1:00 p.m. on October 12, 2020, Employee #1, employed as a carpenter on a residential custom home construction project, was installing a window frame. While stepping through the window opening, he stood on the exterior window ledge, which measured approximately 9 inches in width. A coworker did not observe the incident but saw Employee #1 falling to the dirt ground below. Employee #1 had been reaching for his hammer when he lost balance and fell approximately five feet, 10 inches. The fall resulted in a broken tibia and a dislocated knee on his left leg. Employee #1 was hospitalized for treatment.
