Abstract: Employee #1 was working as a laborer with a company that installed and maintained cell phone installations. On June 5, 2001, a crew of three employees was preparing to install an antenna array at the 18.3-meter level on a monopole. Although the pole was equipped with sockets for removable step bolts, it did not have them installed. The employees waited for an aerial lift to arrive. While they were waiting, the supervisor asked Employee #1 if he was going to climb the pole or wait for the aerial lift. Reluctantly, Employee #1 began to climb the pole using the vertical catenary line and the sockets for the removable step bolts. He was wearing fall protection but did not attach it to a rope grab or the catenary line. When he was approximately 7.6 meters above the ground, he slipped and fell to the concrete surface, fracturing his ankle, foot, and leg. Employee #1 was hospitalized for his injuries.
