[dsg-hallb_rich] Cannot use nitrogen in aerogel tents if people will work inside tents

[Tyler Lemon]

Hi Marco M, Marco C, Sandro, and Dario,

I noticed today that there's now a nitrogen supply line running from the manifold near the window of the cleanroom back to the corner where the aerogel tents are.

I do see that that line is not connected to the manifold, but if people will be working inside the tents, nitrogen cannot be used to purge the tents as it creates an Oxygen Deficiency Hazard (ODH) situation inside the tent.

If it needs to be more dry inside the tents, we will have to come up with a safer way to proceed.
