| Oct. 31, 2007 Air quality
is forecast to be in the moderate range throughout the Southland today
except in the Saddleback Valley area in Orange County, the Corona/Norco
area, and the central San Bernardino Mountains where air quality is forecast to be unhealthy for sensitive individuals
due to the remaining wildfires.
In areas where smoke is seen or smelled or ash is falling:
- everyone should avoid all vigorous exertion, indoors or out;
- residents with heart disease, respiratory diseases including asthma,
as well as the elderly and children should remain indoors;
- keep windows and doors closed unless it is extremely hot inside. In
these cases, seek alternate shelter; and
- turn on an air conditioner if you have one. Keep the fresh air intake
closed and the filter clean to minimize outdoor smoke entering the house.
When air quality is forecast to be unhealthy for sensitive groups,
sensitive or susceptible individuals, such as those with heart or lung
disease, should minimize outdoor activity. When air quality is in the
moderate range, unusually sensitive individuals should consider reducing
vigorous outdoor activity.
Wildfire smoke contains numerous pollutants including microscopic
particles known as PM10 and PM2.5. For a printable fact sheet containing
tips to avoid health impacts from the smoke, see

AQMD is the air pollution control agency for Orange County and major
portions of Los Angeles, San Bernardino and Riverside counties.
