No. We store only the 37% in a flammable cabinet. Ten percent formalin is not considered a flammable substance according to the MSDS for Richard Allen 10% formalin. Which brand are you using. Your storage should be according to the manufacturer's MSDS. Grant it, they should be all on the same page since it is a concrete formula.

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?
