Collinsville’s mix of residential neighborhoods, retail and service businesses, and daily commuting routes can expose people in a few predictable ways during wildfire season:
- Commute and errands: Smoke can intensify during certain wind patterns, making breathing difficult while you’re on the road or running errands in open-air areas.
- Industrial and warehouse work: For employees working around particulate sources or in facilities with HVAC limitations, smoke events can compound existing respiratory risks.
- Schools and childcare: Children are more likely to report symptoms late, and parents may only connect the dots after a series of coughs, wheezing, or fatigue.
- Homes with aging ventilation systems: Some residences don’t filter well or have limited ability to reduce infiltration when smoke levels spike.
Even when wildfire fires are far away, the air quality impact can be immediate—and the health consequences may show up during the event or linger afterward.
