The Air Quality Flag Program alerts schools (or other organizations) to the local air quality forecast and helps them to take actions to protect people’s health, including those with asthma.
Here's how it works: each day your school raises a flag that corresponds to how clean or polluted the air is. The color of the flag matches EPA's Air Quality Index (AQI): green, yellow, orange, red, and purple.
On unhealthy days, your school can use this information to adjust physical activities to help reduce exposure to air pollution, while still keeping students active.
