Air Quality Update

Dear Lab Community,

We are continuing to monitor the air quality in the region.

  • The Bay Area Air Quality Management District has issued an advisory through Tuesday, Nov. 20 due to smoke from the fire in Butte County.
  • Air quality has improved since last week.
  • The weather forecast predicts we will have rain by mid-week.
  • The Lab will continue normal operations on Tuesday, and we will continue to monitor air quality conditions.

Please keep the following options in mind to minimize the impact of smoke:

  • Talk with your supervisor about alternate work options if you have 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 internal air quality monitors located at 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
