In order to facilitate this discussion, can we please just dintinguish
between 10% Neutral Buffered Formalin and Formaldehyde.  10% NBF is what it
is and Formaldehyde  is the ingredient that is mixed with water and buffers
to create 10% NBF.  Again, just for this discussion.  So, are the new regs
which you refer to for 10% NBF or for Formaldehyde which is actually a
corrosive, flammable and carinogen and is actually found in realtively small
quanities in most pathology labs?  Or are you talking about 10% NBF which is
widely used in pathology labs throughout the world. And where can we find
these regulations?
