Matteson’s location in the Chicago metro area means many people experience smoke while commuting, running errands, or working in environments with limited air filtration.
Common local exposure situations include:
- Driving to and from work during heavy haze when ventilation systems are running and visibility drops.
- Shift work and outdoor labor that can’t be delayed—especially when smoke arrives without much lead time.
- School drop-off and youth activities when children are outside before officials issue clear guidance.
- Indoor air that doesn’t hold up—for example, homes or workplaces that rely on basic HVAC without proper filtration or smoke-mode settings.
Even when the wildfire is far away, smoke can travel and still worsen breathing for the people who are most vulnerable.
