Air Quality Index (AQI) Flag Program

​The Broward Air Quality Index (AQI) Flag Program, in partnership with the Environmental Protection Agency (EPA), helps children, parents, the community, and staff become aware of daily outdoor air quality conditions using brightly colored flags. 

Each day, a flag is raised in front of participating entities that signal the level of air pollution for that day. The flag colors correspond to the colors used in the Environmental protection Agency's (EPA) Air Quality Index, which tells how clean or polluted the air is for that day. When members of the surrounding community know what the daily air quality is, they can adjust their activities to reduce their exposure to air pollution. Regular physical activity - at least 60 minutes a day - promotes health and fitness. The purpose of the flag program is to help people continue to exercise and work outside while protecting their health when the air quality is unhealthy.​​

The Air Quality Index

Each day, a colored flag is raised that corresponds to the local air quality forecast:

  • Green flag – good air quality
  • Yellow flag – moderate air quality
  • Orange flag – unhealthy for sensitive groups (including all children and people with asthma)

Note: There is a fourth and fifth color – red and maroon respectively-- used in EPA’s Air Quality Index. They indicate unhealthy (red) and very unhealthy (maroon) air quality. They are not included in the Broward County AQI School flag program because these conditions are rare in South Florida. In the event we do experience unhealthy or very unhealthy air quality, health advisories will be issued from the Environmental Engineering and Permitting Division (EEPD) in the local media.

Benefits of Participating:

To help keep the community safe when air quality is not adequate. 

Air quality can become unhealthy due to pollutants such as ground-level ozone and particle pollution. Ozone is especially damaging to the lungs of children and those who work and play outside. Particle pollution - especially fine particles such as those found in smoke, haze or dust - contains microscopic solids or liquid droplets that are so small that they can get deep into the lungs and cause serious health problems. Children (including teenagers) are at greater risk from air pollution because their lungs are still developing and they breathe more air per pound of body weight than adults. People with asthma are also more likely to have symptoms when pollution is in the air. Children, including those with asthma, can continue to stay active even when air quality is unhealthy by modifying their activities or, in some cases, moving their activities indoors.
