Tons and tons of plastic are burned on a daily basis and its not 'the worst ecological disaster of all time'. Anybody freaking out about the train wreck is being played, WAKE UP. PS. I am standing next to a bottle of Hydrogen Chloride(muriatic acid)....otherwise known as stomach acid.

You really should do better research before you start suggesting others are displaying unwarranted panic or concern over this Ohio event.
First. Polyvinyl chloride (pvc) is different from Vinyl chloride (one of the major chemicals involved in the fire and explosion events).
You can search the following string for specific information on each chemical.
"MSDS Vinyl Chloride Airgas" -- Should provide a link to a 12 page PDF.
The hazard section of that document says:
"Extremely flammable gas. May form explosive mixtures with air. Contains gas under pressure; may explode if heated. May cause frostbite May displace oxygen and cause rapid suffocation. May cause cancer. May cause damage to organs through prolonged or repeated exposure. (liver)"
Then search "MSDS Polyvinyl Chloride Fischer Scientific" which should yield a 7 page PDF document.
The hazard section there says "This chemical is not considered hazardous by the 2012 OSHA Hazard Communication Standard (29 CFR 1910.1200)".
Bottom line is Vinyl Chloride is an inherently less stable and more hazardous chemical than the polyvinyl chloride you are referencing in your post. Contrary to some media claims, the accident site was transporting vinyl chloride.
The burning and explosion of that chemical can result in many harmful chemical byproducts and potentially other secondary chemical reactions in the environment afterward too.
"Vinyl Chloride is a chlorinated hydrocarbon occurring as a colorless, highly flammable gas with a mild, sweet odor that may emit toxic fumes of carbon dioxide, carbon monoxide, hydrogen chloride and phosgene when heated to decomposition."
According to the government published chemistry data below:

Finally you are incorrectly comparing plastics burned across the entire disparate world on a daily basis to a single mega burn event in a concentrated small area over a very small time delta. If you were to somehow burn an equivalent concentrated amount of polyvinyl chloride in the same small region at the same rate (this would be difficult since pvc has an ignition temp near 600F vs the much lower temp of vinyl chloride) over the same time delta, I am certain we would be equally concerned with some of the chemical byproducts there.
What is released when poly heated to decomposition?....and 10 tanker cars is a drop in the bucket. You act like its hard to burn plastic.
Thanks for telling me you didn't bother searching for the msds docs or reading my post.
You have yourself a nice day now.
The MSDS that was changed last week?
If only you had looked and read a little, then you would know better. I was intentional in what I said to search for.

So the animals are just playing dead then?
Exactly
Show me these animals you speak of.......I'll wait.
Burning vinyl chloride produces Hydrochloric acid and Phosgene gas. Phosgene was used extensively during World War I as a choking (pulmonary) agent. Among the chemicals used in the war, phosgene was responsible for the large majority of deaths. Phosgene gas is heavier than air, so it will not rise and disperse - it will consolidate in low lying areas.
HCL is gastric acid....its in your belly right now. Freon readily decomposes to phosgene gas also. I ain't saying its good for you, its just not as dangerous as you are making it out to be. Stand around a bonfire burning plastic and you will be exposed to the same thing....Now lets talk about a MOUNTAIN of tires burning, it would be the equivalent of 10,000 tanker cars burning.
I disagree with your statement. We are not being played. This is for real. Your comparison is not realistic and amounts to comparing many firecrackers being set off across the country compared to a nuclear bomb going off in one place (East Palestine, Ohio). It's obvious for this reason that the two are not comparable.
Vinyl Chloride (VC) is a monomer that if kept below 8 degrees Fahrenheit is a liquid. At 8 degrees F it boils and is a gas. It is used in making Poly Vinyl Chloride (PVC) resin beads for all sorts of end products.
Polyvinyl Chloride is a polymer, a solid used in many different applications. PVC pipes is just one of the uses. It melts at about 172 degrees F.
Both VC and PVC burned is bad news though. Both are toxic. I do not like petroleum based products, especially plastics. I believe it is the source to almost all pollution and is responsible for almost all modern diseases, which are pretty much immuno-neurological diseases.
So the chems in the ground and water are no biggie either? Go for it, drink a bottle of the water from there.
PVC is a stable mostly non-toxic hard plastic. Vinyl Chloride is an unreached version of it that is a toxic, whitish gas that is extremely corrosive and reacts with nearly everything in its attempt to create a more stable Polyvinyl Chloride. It also reacts with air to produce hypertoxic dioxins and other bad things.
Most of the same byproducts when burned.
Controlled burning of PVC vs. uncontrolled I would assume. Either way its bad probably
Its still just burning plastic.
Good for the lungs prolly
