WHAT ISTHE SCHOOL FLAG PROGRAM?
The Flag Program uses colored flags based on U.S.
EPA'sAir Quality Index (AQI) to notify teachers,
coaches, students, and others about outdoor air
quality conditions. Schools raise a colored flag
each day that corresponds to their local air quality
forecast.
WHY WAS THE FLAG PROGRAM DEVELOPED?
The purpose of this program is to create public
awareness of outdoor air quality conditions so
children can continue to exercise while protecting
their health when air quality is in unhealthy ranges.
Children 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.  Even when air quality is unhealthy, exercise
can be  continued indoors for children who have
symptoms outdoors. Recommendations  for outdoor
activities on poor air quality days can be found at
www.airnow.gov under the School Flag Program.
WHAT ISTHEAIR QUALITY INDEX?
The AQI is a guide for reporting daily air quality.
It indicates how clean or polluted the air is and
identifies health effects. EPA uses the AQI for
five common air pollutants: ground-level ozone,
particulate matter, carbon monoxide, sulfur dioxide,
and nitrogen dioxide. For each pollutant, EPA has
established national air quality standards to protect
against harmful health effects.

                                  WHAT DO THE COLORS MEAN?
                                  The Flag Program uses green, yellow, orange, red and
                                  purple flags.These colors correspond to the AQI.
                                                Green means the air quality is good.
                                                No health impacts are expected
                                                when air quality is in this range.
                                                Yellow means air quality is
                                                acceptable. Unusually sensitive
                                                people should consider limiting
                                                prolonged outdoor exertion.
                                                 Orange means air quality is
                                                 unhealthy for sensitive groups ~
                                                 people with lung disease such as
                                                 asthma, children and older adults
                                                 should limit prolonged outdoor
                                                 exertion.
                                                 Red means air quality is unhealthy.
                                                 Sensitive groups should avoid
                                                 prolonged outdoor exertion.
                                                 Everyone else should limit prolonged
                                                 outdoor exertion.
                                                 Purple means air quality is very
                                                 unhealthy. Sensitive groups should
                                                 avoid all outdoor exertion. Everyone
                                                 else should limit outdoor exertion.
                                  HOWWILL I KNOW WHAT COLOR FLAG TO USE?
                                  Check the AQI to know what color flag to use at
                                  www.epa.gov/airnow. Many cities provide an air
