🏭 Illinois Industrial Asbestos Exposure

Illinois industrial workers spent decades around high-temperature machinery, steam systems, boilers, piping, manufacturing equipment, railroad operations, and other systems that historically used asbestos-containing materials.

Factories, steel mills, foundries, power plants, refineries, chemical facilities, railroad shops, heavy-equipment plants, and other industrial workplaces used asbestos because it resisted heat, fire, friction, and chemical deterioration.

Exposure was often greatest during maintenance, repair, equipment overhauls, shutdowns, renovations, and demolition, when workers cut insulation, scraped gaskets, removed packing, opened boilers, repaired valves, rebuilt pumps, or dismantled machinery.

Illinois workers could encounter asbestos directly or simply work nearby while another trade disturbed asbestos-containing material. The original page documents exposure around railroad equipment, heavy machinery, boilers, steam systems, pumps, valves, turbines, compressors, furnaces, and other industrial systems.
