How to protect yourself from wildfire smoke

As smoke from raging wildfires in Canada continues drifting into parts of the United States, it’s critical to know how you can protect yourself from potentially dangerous levels of air pollution. Wildfire smoke contains hazardous pollutants that include toxic gases and particulate matter — solid particles and liquid droplets that are produced when these fires burn through trees, buildings and other materials. While some particulate matter can be easily seen in the form of soot, smoke also carries smaller particles that can infiltrate the human body and affect health. Experts say this pollution could affect your health whether you’re indoors or outdoors.
