Guidance on Improving Ventilation and Indoor Air Quality During Wildfire Smoke Events


The Washington State Department of Health (DOH) provides information on wildfire smoke, including health effects, populations at risk, and steps for preventing and addressing exposure. In 2015, the Department developed guidance for schools and other mechanically-ventilated buildings on how to address ventilation and indoor air quality during wildfire events.
