Mandatory or not, the fume hood is useful for more than just
countering toxic fumes. The more that I consider the build up of
airborne dust and dirt in our lab -- dust primarily caused by dry-
bushing metal artifacts like iron nails for example -- I worry about
long term exposure to the particulate matter. From black lung to
potter's rot, we all know that breathing dust and dirt over the long
term is bad, whether or not the government requires this work done
under a fume hood. I worry much more about long term staff than I do
about a student who does it for one semester during her or his studies.
We plan to install at least one large fume hood in our lab when we get
to remodel.
Cheers,
Tim
