ACGIH Scientific Committees

Experts Advancing ACGIH

Committees are established by and responsible to the Board of Directors. The activities of each Committee are directed by an individual mission statement. Committee members are appointed by the Board of Directors; any ACGIH member interested in volunteering for possible appointment may do so by writing to the Chair of ACGIH in care of the Headquarters Office (3640 Park 42 Drive | Cincinnati, Ohio 45241; phone: 513-742-2020, e-mail: customerservice@acgih.org).

Committee members are not authorized to speak with stakeholders or distribute information about TLVs, BEIs, and other ACGIH guidelines that are under development. Committee members are not authorized to speak as representatives of ACGIH about ACGIH and/or the TLVs, BEIs, and other ACGIH guidelines at scientific meetings, symposia, etc. without consent from ACGIH.
