Margaret,
Your question will elicit a large number od follow-on questions and
comments as it seems somewhat open ended and needs a more detail to
address. Let's start off with a couple basic follow-ups to help.
1.) What size room and what is the typical occupancy?
2.) What is the air exchange rate in the room? Building engineering will
provide an answer. If the number is reasonable stop there.
3.) If the air exchange is marginal (assuming it is a closed room and doors
are generally closed), what type/size is glove box, size of the ante
chamber where gas is exchanged? How often would the box/chamber be opened
during a work period?

Subject: [DCHAS-L] Oxygen Deficient Calculations?
Sent by: "ACS Division of Chemical Health and Safety"
Greetings all,
I hope you may be able to assist. I have been given a project where a
department intends to convert half of a computer lab into a battery
research lab. This room will have glove box using either Argon or Nitrogen,
I have not yet been informed. Does anyone here have a quick method for
calculations?
Among other things is they would like to use a ductless fume hood, but I am
evaluating the intend chemicals for that option as well. Please email me
directly if possible using the email in my signature line.
Thank you very much,
