A union perspective: Nanomaterial exposures in the automotive industry and recent regulatory developments

In the core industries that employ UAW members, manufacturing of automobiles, automotive parts, aircraft and aircraft components, the use of nanomaterials is extensive and growing. The market for nanopowder tire additives is already mature. The markets for nanoclay composites, wear and friction-resistant nanocoatings and mechanically enhanced nanocomposites are maturing now. Many other nanomaterials have already entered the market in such products as catalysts, fuel cell additives, fluid components, coolants, anti-bacterial coatings, soldering additives, paints, coatings, and filters. Other nanomaterials are in the research and prototype stages, where occupational exposure, albeit to fewer workers, still occur. Many of these are expected to enter the market within the next five years. These products are being developed and marketed faster than potential health effects can be identified and faster than worker protections can be developed and/or required. The process of developing OSHA Permissible Exposure Limits has ground to a halt. The only occupational exposure limits being developed for nanomaterials are EPA significant new use rules under the Toxic Substances Control Act. These are being developed in violation of the hierarchy of controls, with the priority placed on personal protective equipment. Unions, along with some allies in the environmental movement are working to get EPA to change the way it makes these rules. This presentation will include a discussion of progress on this effort. In addition, the NIOSH Current Intelligence Bulletin on Occupational Exposure to Carbon Nanotubes and Nanofibers will be discussed.
