Sammye - I don't think I saw you mention
how much sodium azide was being handled and for how long. It will certainly
make a difference in glove selection. I'd have a hard time convincing anyone
that the risk of sodium azide in the lab (an occasional measuring of very
small quantity) would require the silver shield & over glove versus
doubling a pair of nitrile & removing them immediately. If they're
working in manufacturing and handling large quantities for 6-8 hour shifts
- no doubt about the extra protection. This is the same problem with trying
to use industrial standards in the lab. PSM is great but won't apply to
the labs, but I can certainly use some of the concepts.

Not a flaw at all, Monona.
It is simply a statement of economic fact: All gloves cannot
be tested against all chemicals or all possible solvent/solute permutations
unless one has an infinite amount of time, talent and treasure to do such
testing.
If a user is all that curious,
they can, of course, submit a glove sample and challenge agent to an ASTM
testing facility and pay for the test themselves.

All of this points up a flaw in the ASTM
standard test for gloves. It only provides for testing of chemicals
that are liquids at room temperature and pressure, not for solids or solids
dissolved in a liquid. The exception are common chemicals that are
actually gases dissolved in water like hydrochloric acid or ammonia solutions.
I've never seen a substance on any glove chart that was a solid dissolved
in water. So I think you are on your own as far as I know.
