- kurthr 4y agoI'm doubtful on the HF since it's not vinyl fluoride. More likely HCl. Likely, there's some phosgene, though I've read that in large fires that mostly get's burned up. Of course there's CO. The liquid remnants are carcinogenic. https://tsapps.nist.gov/publication/get_pdf.cfm?pub_id=106993 https://tsapps.nist.gov/publication/get_pdf.cfm?pub_id=10699... https://nj.gov/health/eoh/rtkweb/documents/fs/2001.pdf https://nj.gov/health/eoh/rtkweb/documents/fs/2001.pdf
- op00to 4y agoThere’s not nearly enough F in the air to create HF. Where does the fluorine come from? It’s like 5ppb in the air.
- kurthr 4y agoIt doesn't... there is none. Any reporting that says there is likely is confused about other stuff too. I'm open to finding out there was a tank of Fluorine (now that's hazardous cargo!) in a nearby car, but it just sounds like gibberish from here.
- alwayslikethis 4y agoHF? Vinyl chloride does not contain fluorine. It would be HCl instead, which is a naturally occurring mineral acid. The acid rain is going to be a disaster in the short term, but it's not that bad. Phosgene is fairly toxic when inhaled from at a significant concentration, but also dissipates and doesn't stay that long in the atmosphere.
