Cause of Problem: Under Investigation

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.

Discharge Preventable - Under Investigation

Notes/Remedial Actions

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.
