Subject: [DCHAS-L] Glove box inspection checklist?
I have a lab that is using a glove box to maintain an inert atmosphere
with argon while working with lithium ribbon. While the operation looks ok
on the surface, they can't document or prove that they haven't had any
failures (research labs are not production & no one ever thinks of these
things!). Does anyone have a glove box inspection checklist or other info
they can share?
Thanks in advance for your help!

The box does have a gauge on it. I asked
the lab folks if they look at it. They said their test was that if the
gloves were poking out, then they knew it was ok. !! I did remind
them that once they graduate & go to a "real" job, recording
things like pressure gauges in their lab book or checklist were considered
basic requirements for any work. They said they'd set up a log sheet to
do that. Can't make this stuff up!

If you are just looking to to ensure there
are no leaks of gas from the box or into the box, you could do a pressure
test to determine if the pressure remains with an acceptable limit
once filled with argon. The opposite can also be done by performing
a vacuum test, drawing a complete vacuum inside the box and determine if
the vacuum holds then you would know that there are no leaks.
You could also leak a container of liquid smoke inside the box, purge the
box with argon or any other gas and once under pressure watch to see if
any of the smoke escapes from the box.
