Trends Of LVEA Dust Monitors
Attached are trends of the LVEA Dust Monitors.
- Dust Monitor #6 is in the HAM6 Cleanroom
- Dust Monitor #10 is in the Beer Garden
On the 24hr trend, there was a little bit of dust in the LVEA between 8am-1pm, but in the cleanroom, were have been near zero for the last 24 hrs.
On the 4-day trend, the only dust in the HAM6 cleanroom was from technical cleaning on Friday.
Jeff is going to take some more readings outside.

Checked particle counts from outside and inside the OSB and in the LVEA. Summary: Outside air is currently around 330,000 for 0.3um particles. As one moves through the OSB towards the LVEA the counts drop as the building air filtration system does its job. Counts in the LVEA range from 1290 to 270 03.um particles. The attached spreadsheet has the complete readings for all sampled locations. Will continue to monitor as the fire continues to burn.

Second Mid-day check of air around the site shows air quality is not improving. Fires continue to burn or smolder and light wind is not helping clear the air. Posted are the 13:00 hours data. Outside and inside counts are up considerable. Particle counts inside the cleanrooms remain well within acceptable levels for in chamber work.
