Mark, Scott, Chris, and Carolyn worked out at the chamber today. Wipe down with isopropanol was completed and all of Rai's requested samples were taken. The floor was re-installed so that 2nd vacuum could begin early tomorrow.

Zack worked on air drill dis-assembly. Some of the tools for the dedicated clean assembly space arrived today.

Mark H. and I talked about safety concerns related to my "walk" down the beamtube to survey fiber content in the low spots. We agreed that I would only go a short distance down the tube (max. 5 ft) and that Safety will work on a Hazard Analysis for longer beamtube "walk-abouts".
