How does a school district determine the safety of air quality at school sites affected by the wildfires?

There is no indoor air quality standard; however, schools and school districts can monitor local air quality information provided by their local air districts to determine the safety and quality of outdoor air. Schools and school districts can also visit https://airnow.gov to obtain real-time, local air quality conditions.

If air quality becomes unsafe or if local regulatory monitors indicate high levels of particulate matter in the air, keep children indoors where the air is filtered.
