The 1946 constitution revisions abandoned the concept of limiting full membership to only two individuals from each governmental industrial hygiene agency. This opened the doors to all of their professional personnel to participate in the activities of the organization on an equal basis. Governmental industrial hygiene personnel from foreign countries were also given the right to full membership. These changes, among others, were to have a salutary effect on the organization which, in 1946, changed its name to the American Conference of Governmental Industrial Hygienists (ACGIH).
