Oregon Department of Environmental Quality has issued an Air
Pollution Advisory...in effect until noon PDT Monday.
This air quality advisory covers northern Lake and northern Klamath
counties due to wildfires burning in the region. The DEQ also expects
intermittent smoke in central and eastern Douglas County and Jackson
County through this period due to smoke from surrounding fires.
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 and planned
burn operations. 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 and older adults.
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.
