Specialty laboratories and other unique research resources can be used by scientists and engineers in other federal and state agencies, academic institutions, organizations, and companies. Provisions are in place to ensure that EPA research will not be affected by any agreements with other users. EPA's research and development ATF may be used for a variety of research purposes. To find out more about how your agency, business, or organization can participate, please contact: Russell W. Wiener NHSRC USEPA D-205-03 Research Triangle Park, NC 27711 (919) 541-1910 wiener.russell@epa.gov Andre Reinhart 163 USEPA Facilities 26 West Martin Luther King Drive Cincinnati, OH 45268 (513) 487-2119 reinhart.andre@epa.gov EPA's Aerosol Test Facility (ATF) is located in Research Triangle Park, North Carolina. It is available to outside agencies and businesses for research into the behavior of aerosols under controlled conditions. Researchers, engineers, and product designers can obtain highly accurate data that will form a scientifically sound basis for their decisions. The Aerosol Test Facility includes one of the largest aerosol wind tunnels in the world. It has a cross-section of 4x4 meters and can be used with full-sized adult manikins. The ATF offers agencies or businesses all the advantages of a large test facility — without the upfront investment in equipment and continuing upgrades.

Large filters are strategically located in the test section, at the safety screen, and just before the heat exchanger. Doors are equipped with Magnalock switches for safe and easy release. www.epa.gov/nhsrc ------- |
