Most school districts in wildfire-prone states adopted air quality protocols after the 2020 smoke seasons. The protocols establish action levels keyed to AQI thresholds: modified recess, indoor lunch, shelter-in-place. The last action level is shelter-in-place. There is no AQI threshold that triggers closure. Closure requires a recommendation from county health. The document below is one administrator's internal log from a week the air quality went past the protocol's last level and kept going.

Two Registers / Same Air

EPA guidance tells schools what to do at each AQI threshold during wildfire smoke. Schools do what the building, the budget, and the duct tape allow. Both tracks run here through the same six color bands, Green to Maroon. At Green they nearly touch. By Maroon the guidance is five words long and the building is running MERV 8 filters through twenty-six-year-old ductwork with six hundred kids inside.

The Number

2:14 p.m. AirNow registers 151. Orange tips to red. The district server fires an alert to 11,000 phones before any human reads the number.
The principal pulls recess indoors. The athletic director cancels practice. Six coaches scramble for gym space. The custodian closes every window in the building, then checks whether the HVAC is rated to keep running or needs to be killed entirely. Bus drivers switch to recirculate. The nurse pulls asthma action plans from a cabinet nobody opens in October.
Parents who can leave work do. Parents who can't start texting.
