potential to increase to dangerous levels. Persons with
respiratory illness should follow their physicians advice for
dealing with high levels of air pollution.

During periods of stagnant air... state air quality agencies
highly recommend that no outdoor burning occur and that

According to state air quality agencies... prolonged periods of
stagnant air can hold pollutants close to the ground... where
people live and breathe. Check with your local burn agency for
any current restrictions in your area.
