Abstract: At 1:19 p.m. (according to the narrative) on February 23, 2017, an employee was working for a plumbing, heating, and air-conditioning contractor. The firm he worked for serviced HVAC systems. He was accessing the roof of a strip mall to service a new tenant's HVAC system. He was using a Werner 6.4-meter (21-foot) ladder to access a fixed ladder attached to the building. He fell off the ladder and sustained serious injuries. He sustained fractures to multiple ribs, his left hand, and his hip. He was hospitalized. His supervisor was not at the site at the time of the incident. At 4:05 p.m. on that same day, a representative of the firm reported that there had been an incident, that the employee was hospitalized from a fall from a ladder. The employee had been working alone at the time of the fall, and that he refused to be interviewed. Issues regarding this fall from elevation were given as placement of the ladder and training.
