Particle Counter Measurements January 17, 2025
A smoke smell has been reported earlier in the morning (althoguh I haven't smelled anything, potentially because I went downstairs at 11 AM), so I took some particle counts.
| B111A North small table | B111A Outside clean rooms west of north small table | B111B Control area | B111B Outside clean room by northeast shelves | B111B Inside clean room | B111 Antechamber | |
| 0.3 um | 0 | 242 | 197 | 142 | 1 | 2737 |
| 0.5 um | 0 | 40 | 59 | 81 | 0 | 307 |
| 1.0 um | 0 | 31 | 44 | 57 |

The 0.3 um counts outside the clean rooms are ~3x higher than Tuesday, January 14. The larger particle counts are also elevated.
