Purell:
Ingredients:
Active Ingredients: Contains: Ethyl Alcohol (62%)
Inactive Ingredients: Water, Glycerin, Isopropyl Myristate, Propylene
Glycol, Tocopheryl Acetate, Aminomethyl Propanol, Carbomer, Fragrance
(parfum)
The glycerin and propylene glycol would concern me, they're both
hydrophillic. The ethanol in the active ingredient, maybe a mixture of
60% ethanol 35% water 5% isopropanol ( to make it undrinkable, but safe
enough for topical use) would be better around circuit boards. It would
tend to dry the users' hands, but would not help to contaminate circuit
boards.
I've always found hand sanitizer superfluous, just washing ones hands with
soap and water kills most germs.

With the recent news cycle and the concern over the flu virus, several
people in the workforce have been asking if using a hand sanitizer such as
Purell brand would be acceptable to use. From what I can see in the MSDS,
the main component is alcohol, but not all ingredients are listed.
I realize the best approach for actual board contact is a good hand washing
and gloves, but even if we put this stuff in the breakroom, and ask that
people wash and re-glove before returning to the production area, I am
afraid of contaminants reaching the production floor. Also, if we don’t
provide something, I suspect people will start carrying it in and using it
themselves. Has anyone else turned up anything to suggest that it wouldn't
be OK to use this type product in an assembly environment? Any specific
brand recommendations?
If only we could just build boards...Happy Monday!
