An employee was in an aerial lift/bucket truck trimming trees with a pole saw under a 7,620-volt powerline. Wind caught a tree trimming and blew it into the powerline. The tree limb then also struck the employee's left shoulder, creating an electrical connection. The employee suffered an electric shock and burns on the left side, resulting in paresthesia and weakness. They also sustained entry and exit wounds/blistering to the left shoulder and foot.
