Accident Classified As: Reportable Quantity
Cause of Problem: Instrument Failure
On Saturday, March 11, 2013 at approximately 10:00 hours, elevated benzene concentrations were detected in the inlet to the cooling tower. After conducting a series of exchanger testing to determine the source, the site identified an exchanged which had the water side blocked in and filled with benzene product material. The inlet and outlet block valves on the product side were immediately closed.
Discharge Preventable - No
The water side of the exchanger was isolated and drained per procedure on March 7,2013. CRLLC had no reason or indication to suspect that the isolation valves would leak and impact the cooling water system.
