Accident Description
On the evening of January 12, 2009, 2 refinery operators and 2 contractors suffered serious burns resulting from a flash fire at the Silver Eagle Refinery in Woods Cross, Utah. The accident occurred when a large flammable vapor cloud was released from an atmospheric storage tank, known as tank 105, which contained an estimated 440,000 gallons of light naphtha. The vapor cloud found an ignition source and the ensuing flash fire spread up to 230 feet west of the tank farm. On November 4, 2009, a second accident occurred at the Silver Eagle Refinery in Woods Cross, Utah, when a powerful blast wave - - caused by the failure of a 10 inch pipe - damaged nearby homes.
Investigation Status

The CSB investigative team has been continuing its investigation of the hydrogen gas explosion at the Silver Eagle refinery in Woods Cross on November 4. Our preliminary findings indicate that the explosion occurred when a 10-inch pipe failed catastrophically. Although the failure mechanism has yet to be determined, the pipe showed evidence of significant thinning which had not been detected by the refinery’s mechanical integrity program.
