RE: [Histonet] Waste on Benchmark XT

From:"Podawiltz, Thomas"

First of all what does the MSDS state, and what does your state allow? New Hampshire's regulations are tighter than the EPA's and very little is allowed to be drain disposed.  If the waste is flammable, corrosive, reactive or a EPA listed waste, it must be handled as a hazardous waste and disposed of accordingly. We have are waste hauled by a licensed waste hauler.

With all due respect to your university safety department, the fact that they are basing their advise on the "dilution effect" of the sewer system over your waste, it will not just be your waste, but that of all other waste sources that may contain the same DAB and that they absolute do not know.
Because one particular waste source is "small" it does not mean that "in aggregate"all those small sources can make a much larger polluting source.
Dangerous wastes ought not to be discarded down the drain, no matter how small the "may seem to be".

We figured out how much of the waste  components were actually
hazardous, i.e. DAB.  Our University safety department then said that
the small amount of DAB was safe to pour down the drain but they didn't
want the LCS going down the drain.  So we dump the aqueous part and the
oil part we save and they (safety) come get it and incinerate it.

Hello Histoland,

We have a Benchmark XT.  The sales rep told us it was ok to dump the
waste down the drain.  THEN we were told that the waste is hazardous and
actually causes mutant changes in lab animals.  (wow, I could turn into
Rogue or Storm! My luck, I'd be Beast or Toad . . . . .)

Anyway, can I get some feedback from you guys about how you dispose of
the waste from the Benchmark XT?  We had someone here to test it, but
we're still waiting for results.


Amy, Camp Hill PA
