Any of the plastic based fabrics emit a form of cyanide when burned. It’s now thought that many of the firefighter deaths previously thought to have been caused by heart attacks were cyanide poisoning.
The stuff has been found by sensors at fire scenes.
The same plastic fabric is probably in most peoples’ homes unless all of the fabrics in the furnishings are wool, silk, or cotton. There’s an interesting video showing two UL burn rooms on youube.
One has the older fabrics on the furniture. The other has the plastic stuff. The plastic room goes up in flames in an astonishingly short amount of time.
If you have a home fire, get out immediately or there’s a good chance you’ll die like the flag sniffer.
Thanks for that something I didn’t know.
