In prep for closeout of the BSC corner chambers, Camilla assisted me in applying First contact to the ITMY HR surface today.

We used the tooling bracket and wedge to push the ACB out of the way and we painted the cleaning layer onto the surface. It was decided to perform the painting application as opposed to the spray application, after Calum and I quickly l reviewed procedures again this afternoon.  As well, the surface did not seem terribly dirty since there has been very minimal activity in this chamber, 0-5 particles per square inch.

Camilla also took note of the particle counts from the monitor very near the door, which were all around 20 and 40 or less during entry and exit of the chamber.
