1986 Hydrofluoric Acid Release Test

Video of the 1986 “Goldfish” Release Test of hydrofluoric acid (HF) 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.

While the Torrance and Wilmington Valero refineries use Modified Hydrofluoric Acid (MHF) with 6-10% sulfolane to reduce volatility, the amount is too little to prevent a toxic cloud, a fact that has been confirmed by the AQMD.

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.
