How Bad is the Air?
The Utah Department of Air Quality (DEQ) utilizes a numeric index to provide air quality information to citizens. Each day, DEQ rates the air 0-500. To help people who are more visual than mathematical, six colors correspond to the numeric scale. The six categories are explained below.
0-50 (Green): Good -There is little or no pollution and no one is at risk. Outside activities pose no risk. Skies are clear and the air is clean.
51-100 (Yellow): Moderate - For most people, air quality is acceptable at this level. There is no need to curtail outside activities. For a small group of people with extreme sensitivity to air pollution, there are pollutants in the air that could impact them.
101-150 (Orange): Unhealthy for Sensitive Groups - The air quality is worsening, but not enough to impact the majority of people. Outside activities are ok for most. The small group of people with extreme sensitivity may begin to feel the effects of pollutants. This group should avoid or limit outside activities.
151-200 (Red): Unhealthy - Increasing pollutants fill the air. As a member of the general public, begin curtailing outdoor activities and monitor personal health effects. The small group of people with extreme sensitivity will have heath impacts that are getting worse.
201-300 (Purple): Very Unhealthy - The general public may begin to have heath impacts. Avoid strenuous outdoor activities. Those with extra sensitivities should be on high alert as they are in danger.
301-500 (Maroon): Hazardous - At this level, health warnings are issued. Avoid being outdoors unless absolutely necessary. Members of the general population will have heath issues.
We should all do what we can to improve air quality. Understanding the index can help us make personal choices that can protect our health and quality of life.
