It was a chemical reaction that sparked the massive fire and toxic smoke plume at a lab in Georgia that threatened nearby communities and metropolitan Atlanta in September, according to the findings released by the U.S. Chemical Safety Board (CSB). The board released its findings Friday following an investigation into the Sept. 29 chemical fire at a BioLab plant in Conyers, Georgia. The safety board said the main substances involved were a collection of chemicals that are commonly used for cleaning and disinfecting: bromochloro-5,5-dimethylimidazolidine-2,4-dione (BCDMH), trichloroisocyanuric acid (TCCA) and sodium dichloroisocyanurate (DCCA). “The resulting massive plumes of toxic smoke contained chlorine and other hazardous substances and caused significant offsite impacts,” the CSB said. The board will provide its findings and recommendations in its final investigation report.
