Oregon Department of Environmental Quality has issued an Air Quality
Advisory...IN EFFECT UNTIL 5 PM PDT MONDAY.
A Smoke Air Quality Advisory has been issued. Wildfires burning in
the region combined with forecasted conditions will cause air
quality to reach unhealthy levels.
Pollutants in smoke can cause burning eyes...runny nose...aggravate
heart and lung diseases...and aggravate other serious health
problems. Limit outdoor activities and keep children indoors if it

The Oregon Department of Environmental Quality issued an air quality
advisory for Klamath and northern Lake counties due to numerous
wildfires burning in the region.
The wildfire smoke combined with forecast conditions will cause air
quality levels to fluctuate and could be at unhealthy levels.
Smoke levels can change rapidly depending on the weather. Smoke can
irritate the eyes and lungs and worsen some medical conditions.
People most at risk include infants and young children, people with
heart or lung disease, older adults and pregnant people.
People can take the following precautions to protect their health:
- Follow local burn restrictions to prevent deteriorating air
quality.
- Avoid strenuous outdoor activity during periods of poor air quality.
- People with heart or lung problems and young children are
especially vulnerable. These people should stay indoors while smoke
levels are high.
- Use certified High Efficiency Particulate Air (HEPA) filters in
indoor heating, ventilation, cooling and air purification systems.
- Avoid using wood-burning stoves and other sources of indoor smoke
if possible.
DEQs color-coded Air Quality Index provides current air quality
conditions and ranks air quality as follows: Green is good. Yellow is
moderate. Orange is unhealthy for sensitive groups such as children,
the elderly, pregnant women and those with respiratory conditions.
Red is unhealthy for everyone. Purple is very unhealthy for all
groups. Maroon is hazardous.
