Not every bad air day becomes a case—but claims tend to strengthen when you can show three things:
- Your exposure was more than ordinary: prolonged smoky conditions, repeated episodes, or exposure while commuting/working.
- You suffered measurable health effects: documented respiratory symptoms and diagnoses, not just temporary irritation.
- There’s a credible link between the two: medical records and clinician notes that align with the timing of smoke.
In Union, the “ordinary exposure” argument often comes up when your employer, landlord, or an insurer claims the smoke was regional and unavoidable. That may be true in part—but Missouri law still allows claims based on duty, foreseeability, and failure to take reasonable steps to protect people when smoke risks were known or should have been anticipated.
