[Histonet] formalin storage

[Galbraith, Joe]

Amy:

Exactly what do you mean by 'we store all our chemicals in a flammable
storage cabinet'?  By any chance, do you mean that you actually put
everything into the same cabinet together?  I would be very concerned
about putting "everything" into one cabinet (flammable or not).  Some
materials should not be stored together (it's not safe and regulations
require separate storage based on reactive properties).  If this is the
case, please consult your safety officer or use the MSDS sheet or the
internet to determine proper storage.

We have been directed by our Safety Officer to store all formalin (37%
and 10% NBF) in a flammable storage room, cabinet or container.  Yes,
37% Formalin we do store in this manner, but I have never heard of this
requirement for 10%NBF.  I looked on line to many MSDS sheets from
different vendors and found only one that stated such storage
requirements for 10% NBF.  During this search I found all but one
company states that formalin is not flammable.  I brought this to the
Safety Officer.  He agrees that it is not "flammable" but that it IS
"combustible".  Combustible=Flash point of 100F to 200F.  Of the dozen
sites I visited I found the following data concerning the Flash Point of
10% NBF: from "NA / >200F / 122F to 185F".  The NFPA (National Fire
Protection Agency) guideline of no more than 1 gallon in a flammable
storage container and 1 gallon outside of a safety cabinet/container per
100 square feet is already quite limiting.  Using this guideline, we
have calculated acceptable volumes of the known flammables (Alcohols and
Xylenes) we can store.  Adding 10% NBF to the equation will have us
traveling to our "bulk" storage area constantly.  Does anyone out there
store 10%NBF in flammable cans/cabinets?
