Monroe County — Hannibal — is home to the Ormet aluminum reduction works and the river power plants, operations whose high-heat process systems reportedly relied on asbestos-containing insulation and refractory.

Ohio asbestos cases are filed in the Court of Common Pleas of the county of proper venue — there is no single statewide asbestos court, though Cuyahoga County (Cleveland) has historically carried Ohio’s largest asbestos docket. Ohio allows two years from a mesothelioma or asbestos-cancer diagnosis to file (Ohio Rev. Code § 2305.10), and two years from the date of death for a wrongful-death claim (§ 2125.02).
