Air quality improves; normal Lab operations on Monday

Dear Lab Community,
While the region’s air quality has improved significantly since Friday, smoke from the fire in Butte County continues to impact the Bay Area. The Bay Area Air Quality Management District has issued an advisory through Tuesday, Nov. 20. The Lab will continue normal operations on Monday, but please keep the following options in mind to minimize the impact of smoke:
  • Talk with your supervisor about alternate work options if you have any concerns about the air quality at your work location.
  • The Lab’s Health Services in Building 26 is available for consultation. No appointment is needed.
  • We have added internal air quality monitors to five of our buildings to get representative air data so we can understand what is happening across the hill. This data will be used in planning for similar situations in the future. You can access the monitoring information at
  • Protective measures, such as wearing a mask, are an individual choice.  Consult with your personal health provider for more information if you have existing health issues.  If you choose a mask, read more about masks and how to use them.
For more information, see our air quality resource page.
Please monitor your work email and for updates.
Best regards,
Michael Witherell
