Groups" (orange), sensitive groups as specified above should
limit
extended or intense outdoor activity.
* When AQI is "Unhealthy" (red), everyone may experience health
impacts. Sensitive groups should avoid extended time outdoors.

avoid
all outdoor physical activity. Everyone else should avoid
extended

* When AQI is "Hazardous" (maroon), everyone should avoid all
outdoor
physical activity.
* ADDITIONAL DETAILS...
To help keep indoor air clean when air quality is poor:
* Keep windows and doors closed
* Run your air conditioner and/or an air purifier
* Do not use whole house fans or swamp coolers that bring in
outside
air if you have other methods to stay cool
* Avoid other sources of pollution such as fireplaces, candles,
incense, grilling, and gasoline-powered lawn and garden equipment
To help minimize outdoor particle pollution levels:
* Carpool, telecommute, reduce trips, or take public transportation
* Slow down if driving on dirt roads
