Abstract: At approximately 10:30 a.m. on June 24, 2005, Employee #1, with Asplundh Tree Expert Co., was trimming a tree in the backyard of single-family residence. He was approximately 15 to 18 ft above ground using an 11-ft-long wooden pruner. Employee #1 had tied himself to a limb with a harness before starting to trim branches that were near the top of the tree. Energized 12000 volt power lines ran over the house between two power poles. A foreman was working on another tree located about 25 ft away in the same backyard. When he heard Employee #1 call for him, he descended and saw smoke coming from the tree where Employee #1 was working. When the foreman began to ascend this tree, he sustained an electric shock. Emergency responders were summoned. Employee #1 was electrocuted.
