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.
