Abstract: At approximately 11:00 a.m. on November 18, 2011, Employee #1, a Laborer with Complete Decon, Inc., was performing demolition work on a 70-ft-tall metal structure. He was in a Genie S-85 aerial lift cutting sections of metal on the fourth floor with an oxygen and acetylene torch. The lift was not insulated to protect against electrical hazards. Winds were 10 to 15 miles per hour. When the lift platform came within 1 ft of an energized 60,000 volt phase-to-phase overhead high voltage line, an arc flash occurred. Employee #1's clothes ignited and he lost consciousness. A coworker lowered the lift with the ground-level controls and assisted Employee #1 out of the lift. He was hospitalized at U.C. Davis Medical Center for first-, second-, and third-degree burns to his hands, arms, and stomach covering a body surface area of 35 percent. There were no witnesses to the incident.
