Does he require his wife to wear chain mail gloves while paring potatoes?

I once had my safety officer insist I wear chain maille gloves while 
cutting frozen sections.  They didn' t care about all the reasons I gave 
them why I shouldn't - like it would be impossible to use the machine 
while wearing them, and the patient would have to lie on the operating 
table longer waiting to find out if their entire colon was going to be 
removed.

No, it is ridiculous. Safety people tried to argue this with us years ago. 

One of our pathologists told them, "How can something that is almost 90% 
water be a combustion hazard?"

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?
