Debbie,
For most of our applications, the use of a fume hood with a positive air
flow past the workpiece is enough.  We use 1B31 here, and it also has the
toluene.  All our spray machines are vented to the outside with blower
motors (explosion proof) and the manual coating is done in booths with
positive air flow.  You might also consider the fume extractors used for
soldering if you want to get a more point-souce type of solution.

Subject:    [TN] Humiseal


I have a couple of issues with Humiseal 1A20 that I could use some help
with.

The fumes from this material are making a couple of my employees ill when
they use it
in dip application mode. What are the typical application methods for
Humiseal and how
do you protect your employees from the fumes it produces? According to the
MSDS
it is a suspected carcinogen (toluene), plus a respiratory irritant, and
this has us
concerned. If we switch to a spray coating operation are we going to have
to
set up a
dedicated spray booth operation and what are the regulatory concerns with
this,
both safety and environmental?

Thanks for any insight you may provide,
