Protective Measures for Sensitive Groups

When air quality is unhealthy for sensitive groups, everyone is at risk for eye, skin, and throat irritation, as well as respiratory problems. The public should greatly reduce outdoor exertion.

While the broader population might still be largely unaffected, sensitive groups are at much greater health risk and should be very cautious. They should avoid all outdoor activity.
