American Conference of Governmental Industrial Hygienists (ACGIH)

American Conference of Governmental Industrial Hygienists (ACGIH)


ACGIH® is a 501(c)(3) charitable scientific organization that advances occupational and environmental health. Examples of this include our annual editions of the TLVs® and BEIs® book and work practice guides in ACGIH’s Signature Publications.

For over 80 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. This original goal is reflected in both our current mission – the advancement of occupational and environmental health – and in our tagline: Defining Science for OEHS Experts.

This scientific information and data are provided to member subscribers and others in the industry through ACGIH and AIHA’s monthly peer-reviewed journal, the Journal of Occupational and Environmental Hygiene (JOEH), and our professional conferences and seminars, as well as through our vast list of technical and scientific publications, including the renowned TLVs and BEIs book.

American Industrial Hygiene Association (AIHA)

American Industrial Hygiene Association (AIHA)


AIHA is the association for scientists and professionals committed to preserving and ensuring occupational and environmental health and safety (OEHS) in the workplace and community. Founded in 1939, we support our members with our expertise, networks, comprehensive education programs, and other products and services that help them maintain the highest professional and competency standards. More than half of AIHA’s nearly 8,500 members are Certified Industrial Hygienists, and many hold other professional designations. AIHA serves as a resource for those employed across the public and private sectors and the communities in which they work.

AIHA was formed in 1939 and is a non-profit organization incorporated in Illinois (US Internal Revenue Code section 501(c)(6)). An elected governing Board of Directors manages the Association. The Association’s overall objective is to help ensure that work-related occupational and environmental health and safety (OEHS) hazards are anticipated and eliminated or controlled.

It seeks to achieve this by:

  • Promoting the profession and OEHS practice in the industry, government, and the general community
  • Improving the practice of OEHS and the knowledge, competence, and standing of its practitioners
  • Providing a global forum for the exchange of OEHS information and ideas
  • Representing the profession nationally and internationally

Our Mission: Empowering and advancing those who apply scientific knowledge to protect all workers and their communities from occupational and environmental hazards.

Our Vision: A world where all workers and their communities are healthy and safe​.

Value Proposition:  AIHA members are scientists and professionals who protect the health and safety of workers and communities by reducing risks and safeguarding operations to help organizations operate efficiently and without interruption.
