Asbestos Exposure Records

Local 399 represents stationary engineers who operate and maintain the boiler plants, steam systems, and mechanical equipment in buildings and industrial complexes across Illinois and Indiana. These were among the most asbestos-intensive workplaces in the region. Documented jobsite exposure records are maintained at illinoismesothelioma.com and indianamesothelioma.com .

If you were diagnosed with mesothelioma or another asbestos-related disease and were exposed to asbestos insulation, gaskets, or packing while operating boilers and steam plants at buildings or industrial facilities in Illinois or Indiana, documented exposure records may be available for your work locations.

Occupational Disease Resources

Building trades workers who were active during the period from approximately 1940 through the early 1980s were routinely exposed to asbestos-containing insulation, gaskets, refractory, and packing at industrial and commercial jobsites.

Conditions associated with this exposure include mesothelioma, asbestosis, and asbestos-related lung cancer. These conditions can have latency periods of 20–50 years and may not appear until decades after exposure ended.
