Cleaning preparation work was done on aHAM12 (iHAM11).
Construction continued on the H2PSL enclosure with laying of drywall.
I tracked dust monitors during this activity to see if dust from drywall laying was potentially getting into open HAM. Attached is a chart showing today's dust monitor trends, the only significant spike inside the clean room was when the forklift was maneuvering through the doors. Other than that activity was really low (<500) and drywall work doesn't seem to have interfered.
