How toxic is PFA? - (Dec/08/2011 )

I've seen students using 4% PFA to fix cells in room conditions and not under the hood. Is it classified as a toxic chemical?

-science noob-

this wikipedia article can give you some idea:

paraformaldehyde

or click on one of the "msds" links on this product page from sigma:

paraformaldehyde

it is better to do it under the hood.

The fumes can be toxic and it is a known carcinogen, but unless you are heating it it is not usually that volatile I think so I don't think using it on the bench is a problem, as long as you are wearing gloves to protect skin obviously. And don't drink it.

not to diminish the dangers of pfa but, according to the msds, it is a "suspected" carcinogen (with limited evidence in animals and none in human).
