Wildfire Smoke Impacts Air Quality
San Andreas, CA...Smoke from the Northern California fires continues to impact air quality in Calaveras County. The impact varies, based on geographical location and wind direction, but has the greatest impact at this time on sensitive populations, including individuals with heart and lung disease, elderly persons, infants, children and pregnant women. Because the Calaveras County geography may entrap smoke in certain valleys and basins, the
following visibility chart can be used to determine the air quality where you are. Visibility provides an excellent measure of air quality.
To use the chart, start by identifying, on a map, certain landmarks on the horizon. Then check to
see at what distance the landmarks can no longer be seen. The distance of this landmark is the
“visibility in miles.”
General cautionary measures, the following measures can be taken to protect during periods of
poor air quality:
• Minimize or stop outdoor activities, especially exercise

• Stay indoors with windows and doors closed as much as possible
• Do not run fans that bring smoky outdoor air inside – examples include swamp coolers,
whole-house fans, and fresh air ventilation systems
• Run your air-conditioner only if it does not bring smoke in from the outdoors. Change the
standard air conditioner filter to a medium or high efficiency filter. If available, use the
“re-circulate” or “recycle” setting on the unit
• Do not smoke, vacuum, fry food, or do other things that will create indoor air pollution
• If you have asthma, take your medications and follow your asthma management plan
Even healthy persons can be affected by wildfire smoke. If you can see or smell smoke, take
precautions. People with heart or lung disease who experience repeated coughing, shortness of
breath, difficulty breathing, wheezing, chest tightness or pain should contact their doctor or
clinic. “If an existing illness gets worse due to smoke exposure, seek medical help,” advised Dr.
Dean Kelaita, County Health Officer.
The Calaveras County Air Pollution Control District will continue monitoring the air quality in the
county and will provide additional advisories as air quality conditions evolve.
