Re: formalin carboy storage

Unfortunately, some  MSDS list 10% formalin  as a NFPA # 2 for
Flammability.  We have gone in rounds with our safety people and Allegiance
(the manufacturer/distributor)  to get that flammability rating changed. I
can easily understand the  confusion involved.   Can you imagine adding
formalin to the flammable inventory for CAP!   Boy would we be over the

Unless you are using an alcoholic formalin solution, 10%  aqueous formalin
is not flammable. The MSDS for rhe specific formalin product you use should
provide ample information to advise you about storage requirements if you
are unsure of its composition.
I suspect that the surgicenter's position has more to do with their desire
to contain formadehyde vapors that flammability.

We supply a 5 gallon 10% formalin carboy to an off-campus surgicenter
facility for their tissue specimens.  They keep this carboy in a separate
room that is also used for frozen sections.  They insist that this carboy
needs to be kept in a small countertop flammable cabinet.  What are other's
protocol for formalin storage of your opened container and then also your
bulk supply?  We have never kept our formalin in a flammable cabinet.
