Schell Brewery carries brewing-process fire risk with grain handling, fermentation gases, and century-old brewery construction. 3M manufacturing and Kraft Heinz processing add chemical, electrical, and food-processing fire load. Downtown German-heritage commercial has older shared-wall construction.
Smoke damage in Brown County commercial buildings follows the HVAC system — a kitchen fire that seems contained to one tenant space produces smoke that travels through shared ductwork into adjacent spaces, guest rooms above, and common areas throughout the building. The fire department addresses the fire; the smoke migration is what creates the commercial claim. Every surface in the smoke path requires assessment — some need cleaning, some need sealing, some need replacement. The difference between a $50,000 fire claim and a $500,000 fire claim is usually the smoke, not the flames.
