Update on Air Quality

Stanford is continuing to monitor local air quality as a result of the tragic North Bay wildfires this week.

Local air quality is expected to continue to vary based on meteorological conditions. The current Bay Area Air Quality Management District forecast suggests improved air quality tomorrow and through the weekend, but the situation is changeable.

Everyone in the campus community is encouraged to take common-sense steps to provide for their health, including drinking plenty of water and limiting strenuous outdoor activity when smoke is present. The U.S. Centers for Disease Control and Prevention advise that older adults, children, and those with respiratory or cardiac conditions can be particularly vulnerable to the effects of poor air quality and should limit exposure to outdoor air.

Stanford students with pre-existing respiratory or cardiac conditions should check with Vaden Health Center if they experience any distress symptoms. Children in day care centers should have minimal outdoor activity during this period, and parents of children with pre-existing respiratory or cardiac conditions should follow the advice of their health care providers about the prevention and treatment of symptoms.

For Stanford employees, if you are unable to come to work or have concerns about your individual situation, please speak with your supervisor or human resources representative. While university operations are continuing, supervisors should provide flexibility, including alternate work arrangements or leave time if necessary, to support the health of employees. For personnel working indoors, remain indoors as much as possible during the work day. Personnel with outdoor work assignments should limit severe exertion and take more frequent breaks – indoors, if possible. Anyone experiencing health issues related to air quality should notify their supervisor or contact the Stanford EH&S Occupational Health Center.

This weekend’s Reunion Homecoming activities are proceeding. As with the campus community as a whole, Reunion Homecoming guests will be encouraged to take precautionary measures if they have health conditions that make them particularly vulnerable to smoky air.

Stanford Athletics is actively monitoring the Air Quality Index and is prepared to take the appropriate steps to protect student-athletes and fans, in accordance with Pac-12 and NCAA guidelines. At this time, all athletics competitions this weekend are expected to be played as originally scheduled. Stanford Athletics continues to evaluate the situation and will provide updates on this web page:

The university has received some questions about the use of masks. The university is not distributing masks generally for wildfire smoke abatement. Anyone with a health condition that may be exacerbated by smoke exposure should consult with their medical care provider for advice.

Further updates will be provided at, and more information about the university’s response to the North Bay fires is available at

Our thoughts continue to be with the many thousands of people in the North Bay who have been most directly impacted by these fires.

Further updates will be provided on this website.

Wildfire Smoke

Smoke from this week’s devastating North Bay fires has been increasing today in the Bay Area, including around the Stanford campus.

As of early afternoon, the nearest official air monitoring station, in Redwood City, measured an Air Quality Index reading of 160 for particle pollution. This placed local air quality as measured by particle pollution in the “unhealthy” category, which is designated for Air Quality Index readings between 151 and 200. However, the Air Quality Index reading for ozone stood at 19, which is within the “good” range of 0 to 50.

The public health recommendations for “unhealthy” particle pollution category levels include:

For pulmonary-sensitive groups: Avoid prolonged or heavy exertion. Move activities indoors or reschedule to a time when the air quality is better.

All others: Reduce prolonged or heavy exertion. Take more breaks during all outdoor activities.

The Bay Area Air Quality Management District has issued a health advisory for the Bay Area, warning that “due to active wildfires and changing wind patterns, air quality could be impacted for many days to come. Outside of the active fire areas, air quality will be variable and unpredictable. Air quality may improve at times or get worse, very quickly.”

Please take care of your personal health, and that of your family, during this period. The Bay Area Air Quality Management District also is asking Bay Area residents to curtail activities that create additional air pollution, such as driving, wood burning, lawn mowing, leaf blowing and barbecuing.

Suspicious Circumstance — Possible Handgun

This morning at approximately 8:30am, Stanford police were advised of a man sitting in a van in the Maples parking lot who appeared to be loading a magazine into what the witness thought was a handgun. Police responded to the area immediately and were unable to locate anyone matching the description of the person or the associated vehicle.

The reporting party described the person with the possible weapon as an adult male, unknown race, wearing a beige beanie hat. The person was sitting in a white service type van that had blue lettering on it. The word “People” might have been the word in blue print on the van.

The Stanford Department of Public Safety asks the community to report suspicious and criminal activity to the police as soon as possible. Anyone with information regarding this incident should contact the Stanford Police at 650-329-2413.

At this time, the police are not suggesting that people shelter in place.

Siren Malfunction Update

Stanford DPS has been working with the vendors to identify the cause of Tuesday morning’s unintentional activation of the university’s outdoor warning system. Although not the conclusive cause of the activation, it appears there was a system malfunction after a software update that took place at 3am, which resulted in a system reboot. DPS is working with the vendor to ensure the situation will not repeat before we reactivate the siren system. Moving forward, we intend to set controls so that software updates will take place during typical waking hours. Additionally, the vendor will be examining the tower located on Stanford Ave to determine if there is anything about this specific tower that caused it to continue to activate even after the alarms had been cleared in the system.


Accidental outdoor siren activation on October 18

Dear Stanford Community Member,

This morning, Stanford’s outdoor emergency warning system malfunctioned, resulting in an activation of the entire siren system around 3:10am. We were able to deactivate the system; however, the tower on Stanford Ave continued to malfunction. We immediately began working with technicians to remedy the problem. Unfortunately, it has taken several hours to diagnose and resolve the malfunction.

I want to extend my sincere apologies for the inconvenience. We are investigating what caused the malfunction and will take steps to avoid future disruptions.

Updates will be posted on this website when available.

If you have questions, you may contact the Stanford Department of Public Safety at or 650-723-9633.

Annual campus-wide AlertSU test takes place October 13 at noon

On Thursday, October 13, between noon-12:30 pm, Stanford University will conduct its annual test of the campus AlertSU system. Alert messages will be sent via text message and email to the Stanford community.

Also being tested is a new enhancement to the AlertSU system via Cisco VoIP speaker phones. VoIP speaker phones are found in many of the academic and office buildings throughout campus. If you have a Cisco phone in your area, the AlertSU message will broadcast from the speaker phone and a banner message will appear in the display.

The test will also include activation of the outdoor warning system, which will sound an audible tone for approximately 60 seconds followed by a verbal message from each of the 7 sirens at various campus locations. The sirens will be audible throughout the campus and may also be heard in parts of the surrounding communities including Palo Alto, Menlo Park and Los Altos.

There will be a link to a short survey as part of the test email message. Please take a few moments to complete the survey as your feedback will help us evaluate the effectiveness of the AlertSU system.

Prior to the test, it is important you verify that your contact information is correct. Students can update their contact information in Axess, and staff & faculty can update their information in StanfordYou. Make sure that there is an entry in the mobile phone field as this is the most rapid and direct way of communicating with you during an emergency.

Campus IT issues resolved

University IT has corrected the issues that caused connectivity and authentication issues on Friday afternoon and evening. All systems and services should be operating normally. If you have any continuing problems, please sumbit a HelpSU request or call 650.725.HELP.
