Abstract: At 1:59 p.m. on April 11, 2017, Employee #1, a residential installer/technician employed by a telecommunications contractor, was installing a cable for a residential building. He was working from a 28-foot Werner fiberglass extension ladder when he lost balance and fell to the asphalt street surface, a fall height of approximately 22 feet. Emergency services were called, and Employee #1 was transported to the hospital. He was admitted and treated for severe skull fractures and head trauma, a fractured ankle, a fractured wrist, a punctured lung, and significant bleeding. The subsequent investigation determined that Employee #1 had been wearing his climbing belt but had not utilized the belt's lanyard/safety straps.
