As an added note: it was interesting that I could smell the First contact as it was being applied in BSC2 all the way up at HAM5 when I was working there. Just more interesting than anything as shows how the purge can propogate stuff from that chamber all the way to HAM5
I have included photos in case people are also interested in temp or RH in chamber at time
