Abstract: Three employees of an electrical contracting firm were installing a metal cap on the top of a streetlight. They were using an aerial lift (a Simon-Ro TC2863 crane with a Telsta Model No. S434, Serial No. 223021) to work on the streetlight. One employee was on the aerial lift platform, installing the metal cap; another employee was in the truck, operating the controls of the boom; and the third employee was on the ground, standing at the base of the light pole. One of the employees was electrocuted when the platform got too close to a 4000-volt (phase-to-phase) overhead power line. (The original form did not indicate which employee was electrocuted or exactly who or what contacted the power line.)
