that makes sense now...when we make the stuff, we ALWAYS do it in a fume
hood...

Thank you all! I have received many responses already concerning 10%
Neutral Buffered Formalin (NBF) storage. Only one person has stated
that they store all chemicals, including formalin, in safety cabinets.
I just want to clarify something. All MSDS's I studied stated that 10%
NBF indeed is NOT flammable, but the Flash Point is under 200 F on all
but one manufacturer's product. The NFPA99 11.7.2.3.1 and 11.7.2.3.2
rules on flammables storage include all Class I, II and IIIA liquids.
Class IIIA liquids include those with a Flashpoint of less than 200 F.
That would include 10% NBF. It appears to be the formaldehyde fume
(which we all know very well) is the combustible portion no matter if it
is 96.7% water. Most manufacturer's recommendations are for storage in a
tightly sealed container, probably to keep those nasty fumes inside.
One would think that would be sufficient.
