Location: Parts of Harney, Lake, and eastern Klamath counties

The Oregon Department of Environmental Quality issued an air quality advisory Friday for parts of Harney, Lake, and eastern Klamath counties due to smoke from the Bootleg Fire in Klamath County.

DEQ expects the air quality advisory to last until at least Monday morning. DEQ and partner agencies will continue to monitor smoke in these impacted areas. When air quality becomes Unhealthy for Sensitive Groups, shown as orange on the Air Quality Index, sensitive groups may want to consider finding a way to be in cleaner air. People can consider leaving the area until air quality improves, creating a cleaner air space in your home, or finding one in your community, like an air conditioned library.

Smoke levels can change rapidly depending on weather. Check current conditions on the Oregon Smoke Information Blog, DEQ’s Air Quality Index, or by downloading the free OregonAIR app on your smartphone.

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 women.

Protect yourself and your family when smoke levels are high:

  • Stay inside if possible. Keep windows and doors closed.
  • Avoid strenuous outdoor activity.
  • Use high efficiency particulate air (HEPA) filters in indoor ventilation systems or portable air purifies. Or create your own air purifying filter by following these instructions.
  • Be aware of smoke in your area and avoid places with the highest levels.
  • If you have heart or lung disease or asthma, follow your healthcare provider’s advice. 

Cloth, dust and surgical masks don’t protect from the harmful particles in smoke. N95 or P100 respirators approved by NIOSH may offer protection, but they must be properly fitted and worn. They won’t work for everyone, especially children. People with heart or lung conditions should consult their doctor before wearing a respirator.
