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

The South Coast AQMD has issued an air quality alert due to
increased fine particle pollution from wildfire smoke in the region.
The air quality alert is in effect until 2 PM Friday.

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 not 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, keep the time brief and wear a tightly-fitted N-95 or P-100
respirator to help reduce 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 respiratory infections. People with heart or
lung diseases should follow their doctor`s advice for dealing with
episodes of unhealthy air quality. Additionally, people 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 view current and forecasted air quality levels, visit the South
Coast Air Quality Management District website at aqmd.gov or download
the mobile app at www.aqmd.gov/mobileapp. Additional details for
this air quality alert may be available at www.aqmd.gov/advisory.

...AIR QUALITY ALERT DUE TO ELEVATED PARTICLE POLLUTION LEVELS FROM
WINDBLOWN DUST...

The South Coast AQMD has issued an air quality alert due to
increased particle pollution from blowing dust. The air quality
alert is in effect until 6 AM Saturday.

In areas directly impacted by high levels of windblown dust, limit
your exposure by remaining indoors with windows and doors closed and
avoiding vigorous physical activity. Run your air conditioner or an
air purifier. If temperatures allow, avoid using whole house fans or
swamp coolers that bring in outside air.

Exposure to high particle pollution levels can cause serious health
problems, including asthma attacks, heart and lung disease symptoms,
and increased risk of respiratory infections. People with heart or
lung diseases should follow their doctor`s advice for dealing with
episodes of unhealthy air quality. Children, older adults, and
people with respiratory or heart disease should avoid prolonged
exposure and strenuous activities when particle pollution levels are
high.

To help minimize outdoor particle pollution levels:
* Carpool, telecommute, reduce trips, or take public transportation
* Slow down if driving on dirt roads
* Stabilize loose soils

Levels of particle pollution can vary hour by hour and by location
depending on wind conditions.

To view current and forecasted air quality levels, visit the South
Coast Air Quality Management District website at aqmd.gov or

details for this air quality alert may be available at
