spent Sulfuric Acid Tank

Hydrochloric Acid - 8 pounds
Hydrofluoric Acid - 4 pounds
Oxalic Acid - 12 pounds
Cause of Problem: Process Upset

An internal chemical reaction occured due to a nitrogen purge being cut off to the tank. The nitrogen purge is utilized for level indication. It is believed that G-1113 reacted with Oxygen to build up in the tank causing an internal chemical reaction leading to the release of HCL, HF, and Oxalic Acid.
The area around the tank was barricaded and the #7 mitigation tower was activated as a precautionary measure to reduce the tank temperature. Black smoke was being released from the spent sulfuric acid pump down tank.
