Before you worry about legal steps, protect your health and preserve the record.
- Get medical care early and tell the clinician what you suspect (work tasks, building conditions, dates/times, any cleanup or ventilation changes).
- Document the environment: take photos/videos of conditions if safe, save any sampling results you already have, and write down where you were and what happened.
- Save Minnesota-specific proof you can access quickly: incident or safety reports, employer communications, pay/shift records, and any building maintenance logs.
- Avoid “off-the-record” statements to adjusters or coworkers—what feels casual can later be used to dispute timing or causation.
