At 11:45 p.m. on July 26, 2015, Employee #1 was removing the accumulator bottle from the #80 3,000-ton die cast machine. The nitrogen gas bottle and the accumul ator bottle for the #80 die cast machine was connected by a four foot hose. Befo re the accumulator bottle could be removed, the nitrogen gas had to be removed o r isolated. In order to remove the nitrogen gas, both bottles had to be drained of their contents by opening the valves at the bottom of the bottles (the two in ch valve remained open). In order to isolate the nitrogen gas, the two inch valv e at the top of the nitrogen gas bottle had to be closed, isolating the nitrogen gas inside the nitrogen gas bottle, and the adjacent quarter inch valve, which empties the nitrogen from the accumulator bottle, had to be opened. Another empl oyee opened the valves at the bottom of the nitrogen gas and accumulator bottles to release the contents while Employee #1 stood on a scissor lift, waiting for the release to complete before removing the hose, which can store up to 1,200 ps i of pressure. When Employee #1 removed the four foot hose, it hit him twice, ki lling him. According to the employer, the valve at the top of the accumulator bo ttle was closed. Upon review of the scene following the accident, it is unclear whether the valve on the nitrogen gas bottle was not initially open before attem pting to release the contents of the bottles, or if the valve was closed before the contents had been completely released.
