I am a scientist that has been working in the field of toxicology for over 30 years. Not sure what you are getting at but they intentionally set fire to containers of vinyl chloride in hopes to prevent their explosion. You burn vinyl chloride you release phosgene gas. Google WWI and phosgene and see what you get. People are returning to their homes after evacuation and finding dead pets and chickens. Naa, nothing threatening there. Give it another week or 2 and see how fucking stupid your comments are.
