Video of the 1986 “Goldfish” Release Test of hydrofluoric acid (HF), one of the world’s most dangerous industrial chemicals, shows the formation and spread of a ground-hugging toxic cloud. In the test carried out by Lawrence Livermore National Laboratory research scientist Dr. Ronald R. Koopman, 8,300 lbs. of HF were released within 2 minutes. 100% of the acid became airborne in a dense, ground-hugging cloud of deadly HF. Two miles downwind, the HF cloud had more than twice the lethal concentration. Consider that each of the two settler tanks at the Torrance Refinery holds 50,000 lbs. of HF — six times more than the 1986 “Goldfish” Release Test.
Compare these “Goldfish” test results to the large-scale accidental release of the vastly safer alternative sulfuric acid at the Tesoro Refinery in Martinez, California, on February 12, 2014.
While the Torrance and Wilmington Valero refineries use Modified Hydrofluoric Acid (MHF) with 6-10% sulfolane to reduce volatility, the amount is far too little to prevent a toxic cloud, a fact that has been confirmed by the AQMD.
