The investigation determined that the cause of the spent sulfuric acid tank failure was overpressure. The overpressure was caused by excessive heat inside the tank. The heat was created by a mixture of caustic water with the spent acid. Acid mixed with water creates heat. Contents of a vessel, typically acid with a small amount of hydrocarbons, were being pumped into the storage tank but there was caustic water inside where it wasn't supposed to be. The overpressure caused the tank to separate from the foundation, empty its contents and catch fire. The fire was contained in 20 minutes and was out in 45 minutes. Shell fire fighters used two trucks, water, foam and dry chemical to extinguish the flames. The following day vacuum trucks began to pump out the dike which contained the tank contents, foam and water. To prevent reoccurrences, steps have been taken to prevent water from getting into the vessel. In addition, replacement equipment will now have the capability of sampling the contents to be pumped before pumping begins. What we learned in this event will be shared with other Bay Area refineries in CAER meetings and Petrochemical Mutual Aid meetings. It will also be shared with the entire industry by our head office in Houston through the American Petroleum Institute. If you have any further questions about the incident, feel free to call me at 313-3462. Sincerely, t� Diane Kalas Community Relations Manager Martinez Manufacturing Complex SDK:saf
