Air Quality in Redwood City

Introduction

  • Unfortunately, large-scale fires are becoming more common. Even when fires burn hundreds of miles away, the impact on the air here in the Bay Area can be felt for days, sometimes weeks.

    RCSD follows guidelines set forth in the School Air Quality Activity Recommendations, which is a document developed with guidance from the California Department of Education for all California schools.

Keeping Track of Air Quality

    *​​Sensitive Individuals include all those with asthma or other heart/lung conditions. Please inform your child's teacher and the school office staff of any significant health concerns for your child(ren), especially those who may have respiratory challenges due to allergies, asthma, recent upper respiratory infections, etc., as we will be taking extra care with these students. ​​​​​​​

    RCSD families should know that the district prioritizes schools remaining open. Individual parents are the best judges of the conditions under which their students should attend school when schools remain open during days with poor air quality. Parents and guardians may keep their children at home on poor air quality days. This is an excused absence.

Poor Air Quality and COVID-19

  • During healthy to moderate air quality days, RCSD typically keeps its doors and windows open and pulls fresh air in from the outside through its HVAC system. During poor air quality days, those practices change in order to avoid pulling smoky, unhealthy air into the classroom. Even with windows and doors closed and air recirculating, the high quality filters, the additional HEPA filtration systems included in each space, and the use of masks sufficiently reduces the spread of the COVID virus. 

    The San Mateo County Pandemic Recovery Framework (PRF), the document all San Mateo schools currently use for public health guidelines, affirms that with the proper ventilation students and staff can remain indoors safely with windows and doors closed and ventilation systems set on “recirculating,” instead of pulling air from the outside.

    The district will continue to abide by the protocols and require masks indoors onsite on poor air quality days. Should the AQI reach unhealthy levels, the district may dismiss school early to avoid any maskless time indoors.
