Amy,
I would stay away from the powder DAB.  When I was at the AFIP, we used
power DAB. The room was cleared of other techs, full mask, gown, goggles and
gloves were used under a fume hood.  Today, may companies supply the DAB in
tablet form or liquid form.  I have used the liquid form for several years
and have great success.  It sure beats inhaling DAB particles Any of the IHC
companies would work.
