I agree that Nomex is superior to FR. Nomex IIIA meets NFPA 1975, 1506, 70E, and 2112.

I will look for the literature on this, but to quickly answer about the
treated coats vs. Nomex, the companies that sell the treated coats say that
the fire resistance begins to fail after two years. The Nomex is more
expensive, but the fire resistance does not fade.

I have seen some literature on all but the human toxicity of the treated FR

So the discussion in the UC Lab Safety world now includes flame retardant
lab coats and human/environmental potential consequences.

I would greatly appreciate being pointed toward information that would help
us more intelligently discuss these concerns:

How good are FR coats in a real flammable liquid fire? How does that compare
to non-FR lab coats?
Are the treated cloth lab coats inferior to the "Nomex" type?
Do the modern treated FR coats demonstrate any human toxicity or
environmental adverse effects?

Literature that may help us in answering these kinds of questions is what I
am asking you to help me find.

Nitric acid is aqueous, so how can it be flammable (in the Tripoli

Possibly someone who KNOWS told the reporter that it's an oxidizer and at
certain concentrations can cause combustion in contact with combustible
materials....and the reporter took the short root to "it's flammable".
