Air Quality Flag Program

The Air Quality Flag Program uses colored flags based on the Air Quality Index (AQI) to notify staff, students, parents, and the community about the outdoor air quality conditions. The purpose of this program is to create public awareness of outdoor air quality conditions so children and adults can continue their outdoor activities while protecting their health when air quality is in unhealthy ranges. Air pollution can damage the lungs and trigger an asthma attack. Knowing the air quality forecast can help sensitive groups avoid unhealthy outdoor activities during these times.

Each flag represents a different level of air pollution:

Green Flag

Green means the air quality is good. No health impacts are expected.

Yellow Flag

Yellow means air quality is acceptable. Unusually sensitive people should consider limiting prolonged outdoor exertion.

Orange Flag

Orange means air quality is unhealthy for sensitive groups: children, older adults, and people with lung disease such as asthma should limit prolonged outdoor exertion.

Red Flag

Red means air quality is unhealthy. Everyone should limit prolonged outdoor exertion.
