Feb 5, 9:59 AM
→ Feb 6, 10:00 AM
Oregon Department of Environmental Quality has issued an Air Quality
Advisory until noon PST Saturday.
For the Air Quality Advisory, stagnant air conditions will trap
smoke and other air pollutants near the ground where people breathe.
Check with your local health or air agency for current restrictions
on woodstove use. There are often exceptions for those who use wood
exclusively to heat their homes and those with limited income.
People can take the following precautions to protect their health:
* Follow local burn restrictions to prevent deteriorating air
quality.
* Avoid strenuous outdoor activity in smoky conditions.
* 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.
