Air Quality

Updated August 2023

Recent wildfires have brought some questions about air quality and how that relates to steps we take at schools to minimize student exposure. Our schools follow Air Quality Advisory information from local agencies to determine impacts on school activities. This includes the use of the Air Quality Index measured at fire.airnow.gov. We have designated staff checking the site throughout the day on days when air quality is a concern.  

Air Quality Index (AQI) of 0-50 is good (Green)

  • All activities can continue

  • Air purifiers with HEPA filters and HVAC used

Air Quality Index (AQI) of 51-100 is moderate (Yellow)

  • All activities can continue

  • Monitor readings, keep staff aware of sensitive students

  • Air purifiers with HEPA filters and HVAC used

AQI of 101-150 is unhealthy for sensitive groups (Orange)

  • Avoid vigorous outdoor activities and consider holding recess indoors

  • For longer activities such as athletic practice, take more breaks and do less intense activities, consider moving indoors or rescheduling

  • Watch for symptoms and take action as needed. Students with asthma should follow their asthma action plans and keep their quick-relief medicine handy.

  • Air purifiers with HEPA filters and HVAC used
