Biological Exposure Indices Committee


For over 80 years, ACGIH® has been considered a well-respected organization by individuals in the industrial hygiene and occupational and environmental health and safety industry. What began as a limited membership base has grown to the all-encompassing Voting Member category of today. During this time, ACGIH® has grown and expanded without losing sight of its original goal – to encourage the interchange of experience among industrial hygiene workers and to collect and make accessible such information and data as might be of aid to them in the proper fulfillment of their duties. This original goal is reflected in both our current mission – the advancement of occupational and environmental health – and in our tagline: Defining the Science of Occupational and Environmental Health.

The independent National Conference of Governmental Industrial Hygienists (NCGIH) convened on June 27, 1938, in Washington, D.C. Representatives to the conference included 76 members, representing 24 states, three cities, one university, the U.S. Public Health Service, the U.S. Bureau of Mines, and the Tennessee Valley Authority. This meeting was the culmination of concerted efforts by John J. Bloomfield and Royd S. Sayers.

NCGIH originally limited its full membership to two representatives from each governmental industrial hygiene agency. In 1946, the organization changed its name to the American Conference of Governmental Industrial Hygienists (ACGIH®) and offered full membership to all industrial hygiene personnel within the agencies as well as to governmental industrial hygiene professionals in other countries. Today, membership is open to all practitioners in industrial hygiene, occupational health, environmental health, and safety domestically and abroad. In January 2013, ACGIH® members approved an amendment of the organization’s Bylaws, which created a single category of membership – a voting member – who must be employed at least 50% of his or her time in occupational or environmental health and safety. At its first meeting, NCGIH created nine standing committees.
