Abstract: The employer was demolishing the interior of an old jail ward at the Pasadena Police Department. Five employees were working on the 4th floor. Employee #1 was assigned to remove the steel bars on the window, while Employee #2 was to remove the elevator machine room. Both employees were using acetylene torches to cut the pipe and the steel bars. Employee #2 had removed the electrical boxes and conduit and, with the power off and the elevator car on the 2nd floor, proceeded to remove the elevator shaft. He was cutting the 1 3/4 inch pipe when the elevator car descended to the first floor, causing hydraulic oil to rush back to the elevator machine room and spray onto Employees #1 and #2, who were using the torches. There was a squirting sound, then an explosion and a ball of fire. Employees #1 and #2 were seriously burned, suffering 3rd-degree burns on about 40 percent and more than 80 percent of their bodies, respectively.
