I believe in low tech daily checks, too. I've seen techno-gremlins ruin 
lots of things. But my point to the lab, especially since they were trying 
to get compensated for ruined stock due to improper gas = how can they 
prove that there wasn't a leak in the box? The gas reps aren't just going 
to take their word for it that they were sure there was no leak (which 
could also account for the ruined stock). Whether its the gauge or some 
other check, they need to keep the log. From my experience, if you didn't 
write it down, you didn't do it.

Not to be contrary, but the "lab folks" test is much more dependable than 
a gauge which can be broken and misreading pressures.  When they built a 
new wing to our building, the first lab they finished didnÕt have enough 
supply air.  According to which hood sashes were open, there would be flow 
out of the hood into the lab.  The air flow display still read 100 lfm 
which was correct in terms of magnitude.  It just didnÕt indicate that the 
flow was in the wrong direction!  I also once had the risk management 
person in charge of keeping the hoods functioning correctly tell me that 
everything was ok in a lab that had positive rather than negative pressure 
based on what the computer readouts said.   IÕm not saying not to check 
gauges and checklists.  IÕm  saying donÕt denigrate low-tech checks. They 
can be more reliable.

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.

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!
