Abstract: On January 16, 2011, Employee #1, an apprentice telecommunication technician with the General Construction section of PG&E, was wiring a telecom cabinet on the second floor of a building. A grid of racks called "ladder racks", installed approximately 7.5 ft above the floor, was used to run cables to telecom equipment. Employee #1 was standing on the first rung of a self-locking portable ladder, labeling the cables. The ladder rack had a few small bolts with exposed threads protruding horizontally. While descending the ladder and holding the rack for balance, his wedding ring became caught on a protruding bolt. Employee #1 was hospitalized at St. Francis Hospital for removal of the ring and treatment of the laceration. He subsequently had surgery at CPMC-Davies Campus. The employer's safety rules prohibit wearing jewelry where there is a danger of electrical contact, crushing or snagging on machinery, materials, or other objects. Employee #1 had been informed of that policy a couple of weeks before the incident.
