The AQI is based on the United States Environmental Protection Agency (U.S. EPA). The AQI is meant to be used as a guide, designed to assist in your decision-making when air quality is poor. The impact of smoke depends on the sensitivity of the person and the length of exposure, as outlined in the sample chart above.

Monitor local air quality conditions using air quality tracking tools recommended provided by the district at

When air is unhealthy, the best option is to reduce physical activity and stay indoors with windows/doors closed. If indoor temperature is high, get to a location with clean filtered air such as a public library, shopping mall or other building with heating, ventilation, and air conditioning (HVAC) system filtration.
