41 - I was responding to the 'closing off compartments' - I guess I should have specified. The 'soapy water' leak detection is a dumb idea. Simply save air and at the same time narrow down the search by compartment - step one in emergency procedures.

It would seem possible to get some "traceable" gas up there in the next supply run (and I'm not sure what it would be!0 that an external sensor could distinguish from normal "vent gasses" outside the lab.
Then, run a scan of the trace gas from outside. For example, in the lab, several gasses are more visible in IR than O2 or N2, so this lets you "see" them with a external leak detector.
Good exmple is a Freon sniffer check done by plumber and HVAC contractors. Also auto mechanics.
