Polk County — Des Moines — carried the Firestone tire plant, the Delavan and Ruan works, and the utility and manufacturing operations of the capital, where high-heat process and power systems reportedly relied on asbestos-containing insulation and materials.

Iowa allows two years from a mesothelioma or asbestos-cancer diagnosis to file a personal-injury or wrongful-death claim (Iowa Code § 614.1(2)), with the clock running from diagnosis under the discovery rule of Iowa’s asbestos-claims act (Chapter 686B). Iowa also requires a sworn medical affidavit to be filed with the complaint (§ 686B.3). Cases are filed in the county District Court of proper venue; Iowa has no statewide asbestos MDL.
