|LDEQ Accident Number
|Point Source(s)||Notes||Amount of Release|
|Cause: During the manfacture of Genetron G-143a (a refrigerant), a transfer hose was attached to transfer chlorine gas from a railcar to the manufacturing process unit, and the transfer hose failed.
At the time of the refinery letter dated 8/17/2005, the root cause of the release was still under investigation.|
Notes: Chlorine sensors, which are installed around the railcar, picked up chlorine vapors, and activated an alarm in the control room. The control room operator remotely shut off the chlorine flow, and then shut down the entire G-143a manufacturing process. The refinery's emergency response team conducted fence line monitoring using colorimetric tubes, and it detected no chlorine downwind during the release event along the south fence line.
|piping||Cause: The plant experienced a pipe leak in the OMNI 143A unit.
The pipe integrity had been compromised during certain operating conditions of the unit that occur on an infrequent basis. These operating conditions are called catalyst burn downs. The pipe leak most likely developed during previous catalyst burn downs.|
Notes: The unit was immediately shutdown to stop the leak. Water was also applied to the leak in order to minimize the emissions. The entire segment of the pipe that the leak occurred on was replaced with Teflon lined pipe in order to improve the integrity and prevent any future incidents.
