...AIR QUALITY ALERT FOR ELEVATED OZONE AIR POLLUTION AND ELEVATED
FINE PARTICLE POLLUTION LEVELS DUE TO WILDFIRE SMOKE...

The South Coast AQMD has issued an air quality alert in the South
Coast Air Basi n due to high levels of ozone (smog) and increased
fine particle pollution from wildfire smoke in the region. The air
quality alert for smog is in effect until Monday evening. The air
quality alert is in effect until Saturday afternoon.

High ozone levels are expected to impact most of the South Coast Air
Basin. Smok e is expected to impact the Inland Empire and the San
Bernardino Mountains.

Elevated levels of ozone - the predominant summertime pollutant -
are likely to result in poor air quality in the afternoon and early-
evening hours. Ozone air p ollution can cause respiratory health
problems, including trouble breathing, ast hma attacks, and lung
damage. Children, older adults, and people with asthma or COPD may
be more sensitive to the health effects of ozone.

Air quality can change depending on time of day and weather
conditions. Increase d emissions of chemicals and faster ozone
formation rates due to heat, along wit h low winds and stagnant
weather can cause unusually high and persistent levels of ozone
pollution.

If you smell smoke or see ash due to a wildfire, remain indoors with windows and
 doors closed or seek alternative shelter, if feasible. Avoid vigorous physical
activity and run your air conditioner and/or an air purifier. If possible, do no
t use whole house fans or swamp coolers that bring in outside air. Avoid burning
 wood in your fireplace or firepit and minimize sources of indoor air pollution
such as candles, incense, pan-frying, and grilling. If you must be outdoors, kee
p the time brief and wear a tightly-fitted N-95 or P-100 respirator to help redu
ce exposure. Limit the use of gasoline powered lawn and garden equipment.

Exposure to particle pollution can cause serious health problems, aggravate lung
 disease, cause asthma attacks and acute bronchitis, and increase risk of respir
atory infections. People with heart or lung diseases should follow their doctor`
s advice for dealing with episodes of unhealthy air quality. Additionally, peopl
e with respiratory or heart disease, older adults, and children are particularly
 susceptible and should avoid prolonged exposure, strenuous activities or heavy
exertion as conditions dictate.

Levels of particle pollution can vary hour by hour and by location depending on
fire behavior and local weather conditions.

To help minimize ozone air pollution levels:
- Limit the use of gasoline powered lawn and garden equipment until
  evening hour
- Conserve electricity and set your air conditioner at a higher
  temperature
- Try to delay trips to the gas station and the use of
  household chemicals until the evening

Check air quality levels and take appropriate action as needed.  When air qualit
y index (AQI) levels are Unhealthy for Sensitive Groups (orange), people with he
art or lung disease, pregnant women, children, and older adults should limit pro
longed or heavy outdoor exertion. When air quality reaches Unhealthy (red) AQI l
evels, everyone may experience adverse health effects and sensitive groups shoul
d avoid prolonged time outdoors. At Very Unhealthy (purple) AQI levels, sensitiv
e groups should avoid all outdoor physical activity and everyone else should avo
id prolonged or heavy outdoor exertion.
