Ohio train crash

Am hearing there was a train derailment in Ohio on the 3rd Feb 2023. The train was carrying a cargo of vinyl chloride which caught fire after the accident. Apparently they are doing a controlled burn off of the chemicals, but when burnt this releases hydrogen chloride and phosgene gases which can be immediately lethal. They have evacuated everybody within a 2 mile radius. People are finding dead cows, chickens fish etc as far away as 100 miles, Wtf.
