That's the real poison. Forget hydrochloric acid, forget phosgene. Dioxin is some real bad shit. Remember Seveso? https://en.wikipedia.org/wiki/Seveso_disaster >Dear Friend and Reader: > Most coverage of the train wreck in Palestine, Ohio is missing one word: dioxin. There were reportedly 14 tanker cars full of vinyl chloride, a precursor to polyvinyl chloride — that is, vinyl. Burning vinyl is the most serious source of dioxin in the environment — whether from trash incinerators, house fires or chemical spills. > While vinyl chloride is a precursor chemical to making PVC, any time chlorinated compounds burn there will be dioxins created. And dioxin is a manufacturing byproduct of any manufacturing process involving chlorine, from “disinfectants” to the bleaching of paper. There was plenty of dioxin in those tanker cars before they caught fire. > This mess of 14 tanker cars (really, many more, but 14 had vinyl chloride) was then set on fire by the government, apparently to make it easier to clear the railroad tracks. This was the worst possible decision. It has turned many, many miles into what should be no-man’s land. But I have not heard of one single test for dioxin being done. > Note that dioxin goes by several other names, including TCDD, and is sometimes abbreviated “2,3,7,8.” Dibenzofurans, or furans for short, are identical in their toxicity but are spoken about less often. Many other chemicals, such as PCBs, are “dioxin-like compounds.” ...
