Industrial Gas Manufacturing

NarrativeAt approximately 3:00 a.m. on December 13, 2017, an employee was working for a firm that manufactured industrial gases, such as for welding. He was strapping cylinders to a metal pallet. To do this, he was operating a ratchet mechanism by pulling its handle. He was standing with his left leg in a kickstand position behind him. As he pulled the handle, the grip handle pin came out of its bracket or housing mounting points. The built in circlips on either sides also came out with the pin. This mechanical failure of the grip bar caused the employee to lose his balance. He fell at grade level with his left leg behind him. He thus sustained a fracture to his left femur. He was hospitalized.

NarrativeAt 10:00 a.m. on October 2, 2017, an employee was working as the general manager of operations for a manufacturer of industrial gases. He was disconnecting purge pig tail connectors from acetylene cylinders. The employee was working alone in the firms Nitrogen Purge Building. The building was a wood structure with a tin roof and siding. The acetylene bottles had undergone a 48-hour purge cycle. The employee had disconnected the last cylinder from the purge line pig tail connector. He discovered that the cylinder was still pressurized and that acetylene gas was escaping. He attempted to close the cylinder valve. The valve was stuck, so he turned to go get a wrench. At that time, the escaping acetylene gas ignited. The heat from the fire melted the fusible plug valves on adjacent cylinders. They too released gas, adding to the fire. Approximately 40 cylinders had fusible links melted. Each had escaping gas that ignited and burned. The fusible plug valves performed as designed, though, and no cylinder explosions occurred. The building caught fire and burned. The employee was able to escape. He sustained second degree burns to his right arm, back and abdomen. He sustained a third degree burn on his left arm. He was hospitalized for two or more days.

NarrativeAt 9:45 a.m. on February 6,2017, an employee was climbing a ladder when he fell and struck his head. The employee was hospitalized and received treatment for his injury.
