Smoke and Wildfire

smokey sky in Portland Wildfires in the Northwest have increased since the 1980s. Scientists attribute this to human-caused climate change. This means more bad air days from wildfire smoke in Multnomah County.

When wildfires burn, winds can push smoke into populated areas. Wildfire smoke is full of different pollutants, including particulate matter and carbon monoxide. We also see high ozone levels. Breathing in smoke can cause health problems for sensitive groups and healthy adults.

Prepare for a smoke event:

Plan for a clean air room at home to protect from wildfire smoke:
- Purchase or make an air cleaner.
- Clean or replace air filters if you have AC or an air cleaner.
Learn about masks (Watch this video).
- A NIOSH approved N95 or other particulate respirator can be an option if you have no other way to avoid smoke. NIOSH approved respirators do not come in suitable sizes for very young children and have not been tested for use in children. Effective use requires proper selection, size and fit. See Western States PEHSU guidance on respirator use by children.
Have a several day supply of medications plus groceries that don’t require cooking.
Make a plan in case you need to evacuate because of smoke or wildfire risk.
