Thanks for the question. I will also be
involved in
dismantling a fume hood that used HF. What should I be concerned
with?

Dear CHAS Members,
I’m looking for some advice and
information. Before
dismantling for disposal, do you have a standard practice of testing
regular
Laboratory Chemical Fume hoods ducts for the presence of
perchlorates? (I’m not talking about Perchloric Acid
Fume hood
here). The question arises because for many hoods, the history of usage
is not
known and in the past unknowingly users may have used such fume hoods
for
heating perchloric acid in ashing procedures. We have a number of
old fume
hoods dismantled and replaced by new ones, so far without any
problems. I
would very much appreciate your advice.
Sincerely,
Prabhat Goswami
