Fire is a natural part of many landscapes, but that doesn’t make the smoke and soot any less deadly. Particulate matter from these fires can drift for miles, and the extremely small particles can more easily infiltrate buildings than particles from vehicle exhaust. These particles can irritate the eyes, nose and throat, and the smallest ones can enter a person’s lungs, even the bloodstream, and damage a person’s heart or respiratory system.
