Instructions:

If driving, slow down and leave plenty of distance ahead of you. Pedestrians and cyclists should wear bright or reflective clothing to increase the chances of being seen by others in poor visibility conditions. State air quality agencies highly recommend that no outdoor burning occur and that residential wood burning devices be limited as much as possible. 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. People with respiratory illness should follow their physician's advice for dealing with high levels of air pollution during periods of stagnant air, especially if an Air Quality Alert is in effect for your area.
