[DCHAS-L] Hand sanitizer

bring the whole aspect of hand hygiene to the student's

Thank you (and everyone else) for your
input.
I do not
wish to seem disputatious, but I think there are two reservations
concerning your answer.
1) Hand
sanitizer, as it is not wiped off, merely moves contamination over a
wider area.
2) Hand sanitizers are
principally ethanol, which may increase the permeability of the skin,
increasing the rate of absorption of a chemical until such time as the
hands are actually washed.
Again, I
feel that what important here (and I may have an exaggerated sense of
its importance) is the distinction between behavior in the lab and the
=93civilian=94 world.
For instance, it is relatively safe to sit on the floor or on a
desk in the civilian world, but not in the lab. I think Bertrand Russell
sited the example of smoking as generally undesirable, but in a
nitroglycerin factory, criminal.
