Over 87 Years of Service to OEHS Professionals

For over 87 years, ACGIH has been respected for its dedication to the industrial hygiene and occupational and environmental health and safety communities. We have grown and expanded without losing sight of our 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.

ACGIH Vision

To consolidate a global interchange of scientific knowledge supporting worker protection and to prevent occupational and environmental illness and disease.

ACGIH Mission

To advance occupational and environmental health globally by providing educational programs, scientific data, and technical knowledge to Occupational and Environmental Health and Safety (OEHS) professionals in the interest of workers and the public.
