[Histonet] Refrigerate formalin?

There is nothing against cooling formalin fixed tissues, but my question is WHY?
I see it as a waste of refrigerated space. 
On the other hand also, IF by any change there is a formalin spill inside the walk-in cooler room, that will be a royal mess to decontaminate.

We're getting ready to move into our new building (YAHOO!) in early
September - finally.  In planning where we will store our cases for the
required 6-week retention time, I have proposed that the tissues (in 10%
NBF) be shelved in the walk-in cooler (4 degrees C).   Is there any
reason tissues-in-formalin could NOT be stored refrigerated for that
length of time?  It is extremely rare that we are required to pull and
recut wet tissue, but that possibility always exists.  Thanks, everyone.
