This caught my attention; thank you.
While I was able to find information blasting PVC on a lot of pro environmental sites, green guides, friends of the earth, greenpeace, etc., oddly enough there was nothing for PVC (or polyvinyl chloride, or vinyl as it's colloquially known) in the U.S. government's HAZMAT directory. And there's a lot listed in that directory of immediate consequence to protecting public safety.

Furthermore, as aphie thoroughly posted, PVC is (and has been for decades) commonly used in construction, furniture, toys, etc. Vinyl siding, anyone? In other words, it's everywhere.
So it seemed reasonable for me to question whether PVC gives off "hydrogen cyanide gas" since the same government HAZMAT site insists that extreme measures be taken when dealing with the release of such gas, even a small amount; it's very toxic. Such precautions include evacuating everyone within 200 meters of its release (within 1 mile if bulk transport), wearing complete protective suits, etc. Would seem a bit unusual if at nearly every home and commercial fire citizens anywhere near the blaze were dropping in the streets like flies, clutching their throats gasping for air as cyanide poisoning rapidly blocked their bodies' oxygen utilization.
It would surely preempt Fox News' usual coverage of criminal car chases. "Look, dear, Fox is running another neighborhood fire and cyanide disaster. Hey, that house has vinyl siding! Look, there's a tell-tale sign--the first firemen on the scene have already died; they weren't suited up when their trucks rolled in. Let's see if we can beat our old body count of 150 neighbors dead in the streets trying to flee." Humorous? Not really. Note here in the reference below that only 300 ppm (parts per million) are enough to kill a human being in minutes. Surely that's something we'd all have noticed by now.

Perhaps PVC gives off other toxins when burned, as do many products. (As do exploding volcanoes and in larger quantities than the entire combined history of modern industrialization.) I'm not a specialist in hazmat nor a chemist and I invite other comments more knowledgable about it than I am. For starters, I would like to examine the source of the claim that "burning PVC releases hydrogen cyanide gas" and then trace back its references to empirical studies.
Not referring to fxtrading with my next comment; it might be an error that was posted, or maybe I don't understand the chemistry. But on principle, the problem with environmentalists is that ultimately they are nihilists; which is to say, they're their own worst enemy--they hate themselves. And by saying anything to justify an agenda, they end up saying nothing.
yep my bust -pvc gives off hydrogen chloride, dioxins and phosgene gas
