[Dsg-htcc] HTCC O2 Concentration

[Will Phelps]

Hello Jennifer,
We are not purging the HTCC volume with dry air and we would like you to check the O2 concentration before we open up the volume for maintenance(in accordance with the OSP). We don’t currently have an estimated time for the O2 concentration to reach a safe level as of this moment, but as soon as we know anything we will let you know. Also, we currently only have one way to measure the O2 concentration, the safety monitor, so we will attempt to use this to measure the concentration at the exhaust unless you advise otherwise.
Thanks,
-Will
