Type in "Oxygen Depletion Calculator" in google. The first hit is a spreadsheet from warwick.ac.uk. It is a spreadsheet download that helps you determine the level of displaced oxygen.

Subject: [DCHAS-L] O2 Sensor Determination

 

Does anyone have a good reference for determining when a room needs an O2 sensor? I'm looking for an amount of liquid gas (nitrogen, argon, helium) vs cubic feet calculation. (We're assuming total catastrophe here: no ventilation and all the cryo-liquid escapes). Dartmouth is looking at doing an overhaul of all the O2 sensors on campus. Facilities will oversee maintain/scheduling of these sensors and require a "hard and fast" rule from EHS to justify their installation.
