Franklin County — Columbus — carried the Buckeye Steel castings works, the rail yards, and the utility and institutional plants of the capital, operations whose high-heat and building systems reportedly contained asbestos.

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).
