National Occupational Exposure Survey (NOES)
From 1981 to 1983, NIOSH conducted the National Occupational Exposure Survey (NOES) that collected data on potential occupational exposures to chemical, physical, and biological agents. The survey involved on-site visits to 4,490 establishments in 522 industry types [OMB 1972] employing approximately 1,800,000 workers in 377 occupational categories[Census 1980]. Nearly 13,000 different potential exposure agents and over 100,000 unique tradename products were observed during these on-site visits.
Field guidelines, sampling methodology, and an analysis of management interview responses have been published [NIOSH 1988, 1989a, 1989b]. However, the bulk of the data remains unpublished. The NOES database has not been updated since July 1, 1990.
