Overview
AIHA has long been a global leader in advancing OEHS knowledge, delivering high-quality education, and developing practical tools relied upon by professionals around the world. From guidance documents and training programs to international partnerships, our work continues to shape the future of worker health and safety.
To strengthen our reach and better serve the OEHS profession, the AIHA leadership team has been in discussions with ACGIH to explore deeper alignment and assess the feasibility of a strategic integration. ACGIH has spent decades advancing the science of occupational health and resources that are foundational to our field, including the development of TLVs and BEIs.

Integration Discussion: FAQs
AIHA and ACGIH leadership are exploring a deeper organizational alignment by combining ACGIH and AIHA’s Guideline Foundation into a new entity. We aim to strengthen long-term sustainability, greater efficiencies, enhance service to the profession, and expand global impact.
The exploration is driven by:
- Long-term sustainability
- Mission alignment
- Strengthening the profession’s global voice
- Improving efficiency and collaboration in programs and services
Current discussions emphasize protecting:
- Scientific integrity
- TLVs, OELs, and technical rigor
- Committee expertise
- ACGIH brand and identity
Scientific independence is a central consideration, with governance and communication guardrails being evaluated specifically to ensure credibility and to avoid any perception of commercialization or undue influence from industry. The integrity that is the hallmark of the ACGIH TLVs will be maintained.
The details are still being discussed between the AIHA and ACGIH Boards. As currently proposed, the majority of ACGIH’s content such as TLVs, BEIs, and their technical committees will join with AIHA’s Guideline Foundation to form a new entity. Education and training currently offered by ACGIH may be brought under those respective programs within AIHA.
No. ACGIH will maintain its brand within the New Entity structure. AIHA will still function as AIHA. OELs and ERPG will continue to function as they have been functioning.
The AIHA Guideline Foundation name will be changed to better reflect the activities and contributions of both organizations.
Members may benefit from:
- Expanded professional network and collaboration opportunities
- Combined educational and technical resources
- Greater influence in policy and global OEHS initiatives
- Reduced duplication across programs and offerings
Membership structure, benefits, and pricing are still under evaluation. Both organizations are actively reviewing options to determine future models.
Yes! One of the best benefits is providing the TLVs and BEIs with a strong ecosystem that includes the ERPGs and OELs.
Programs and committees are expected to continue, with ongoing evaluation of how to align and integrate them while maintaining technical rigor and expertise.
ACGIH content scheduled for 2026 will continue as scheduled.
Membership in either organization and its committees remain as-is for 2026. You are not immediately or automatically rolled into an AIHA or ACGIH membership if you are not currently a member of that association. The details for 2027 renewals will be announced later this year.
No. The 2026 membership status and benefits remain the same. If you are an ACGIH member, you will continue to receive your ACGIH benefits.
No. The 2026 member status and benefits remain the same. If you are an AIHA member, you will continue to receive your AIHA benefits.
- Evolving challenges in the OEHS/IH profession
- The need for stronger collaboration and efficiency
- A shared interest in long-term sustainability and impact
This could:
- Strengthen the profession’s unified voice
- Enhance global influence
- Improve coordination of science, standards, and practice
No. This is a decision-in-process, although both Boards have affirmed their commitment to move forward in good faith negotiations regarding the proposed organizational realignment.
Both Boards are evaluating options, gathering input, conducting due diligence, and identifying next steps before a decision to integrate is mutually approved.
Subcommittees have been created and are working on timelines. More information will be shared as it becomes available.
Engagement & Transparency
Members will be able to:
- Submit questions and feedback via a dedicated online form
- Participate in town halls
- AIHA members may participate in a dedicated thread on Catalyst
Feedback will be collected, reviewed, and used to:
- Identify key themes and concerns
- Inform Board decisions
- Shape future decisions and communications
Planned engagements include:
- A series of joint member town halls
- Ongoing email updates and communications
- A central FAQ/landing page with current information
Governance & Structure
Governance structures within the new entity are under evaluation, including:
- The new entity Board composition
- Representation from both organizations
ACGIH representatives will maintain oversight of TLVs.
- Yes, the new entity will see some changes in structure with the incorporation of ACGIH.
- Leadership is exploring the best potential structure, including how assets and programs might be aligned under a unified framework. No final structure has been decided.
