    Future/Past Dates

    Future and past AIHce EXP dates and locations.


    In the beginning...

    In 1961, AIHA® and ACGIH® jointly sponsored the first wholly separate conference and exposition for industrial hygienists. Up to this point, AIHA had been invited, since its founding in 1939, as a participant organization in a joint conference lead by the American Association of Industrial Physicians and Surgeons (AAIPS).

    Through 2022, AIHA, with help from ACGIH, has held what is now known as AIHce EXP. Featuring more than 200 exhibitors and nearly 4,500 attendees, this annual conference is known as the premier event for OHS professionals around the world. In 2020 and 2021, due to the COVID-19 pandemic, AIHA canceled its live events in Atlanta and Dallas, and instead held a fully virtual conference online. The conference returns to a robust live format in 2022.

    Looking for some easy icebreaker material at your next conference networking event? Here are some interesting conference facts:

    • AIHA's initial formulation occurred at the American Conference on Occupational Diseases and Industrial Hygiene conference in Cleveland in June 1939.
    • The 1961 conference had just over 700 attendees (including exhibitors).
    • The conference is typically located in cities with convention/conference centers capable of handling a large number of anticipated attendees.
    • Poster sessions were introduced into the conference program in 1977.
    • The first AIHA conference (in partnership with AAIPS) in 1940 was free to attendees; the registration fee in 1941 and 1942 was $1.
    • The 1971 conference in Toronto was the first AIHce held outside the United States.
    • In Houston, Texas, the 1980 AIHce was held for the first time outside of a hotel at the Albert Thomas Convention Center. The conference has been exclusively held at conference and convention centers since then.
    • In 2020 and 2021, AIHA canceled the in-person event due to the COVID-19 pandemic; instead, AIHA moved on its own to hold these conferences as 100% virtual conferences.
