CSB wants EPA to update HF study in wake of refinery fires
The US Chemical Safety Board (CSB) is calling on the EPA to review its existing Hydrofluoric Acid (HF) study to determine the effectiveness of existing regulations as well as the viability of utilizing inherently safer alkylation technologies in petroleum refineries.
In a letter sent to the EPA, the CSB notes that in the last four years, the agency has investigated two refinery incidents where an explosion elevated the threat of a release of HF.
