Indoor Air Quality Program

State licensing/certification is also required for persons performing asbestos-related or lead-related activities in certain buildings. For listings of licensed/certified entities in these fields, see the DSHS Asbestos Program and the DSHS Environmental Lead Program.

National Professional Organizations
There are several national professional organizations that offer certifications relating to indoor air quality and environmental health issues. Three such organizations are:
- The American Board of Industrial Hygiene (ABIH) - The ABIH, a not-for-profit corporation, is the certifying board through which individuals must test and be evaluated for the title of “Certified Industrial Hygienist” (CIH). The science of industrial hygiene is dedicated to anticipating, recognizing, evaluating and controlling the causes of occupational illness. To search for go to the ABIH Public Database. You can enter “TX” in the state field and it will give you a list of CIHs in Texas.
- The Indoor Air Quality Association (IAQA) - The IAQA is a nonprofit, multi-disciplined organization, dedicated to promoting the exchange of indoor environmental information, through education and research, for the safety and well being of the general public. To find a member in your area, click on the “Find an IAQA Pro” link at the top right hand corner of the IAQA website.
- The American Council for Accredited Certification (ACAC) - The ACAC has several certifications relating to the indoor environment and indoor air quality. For a listing of ACAC-certified Professionals, go to the ACAC search page.
In addition to the groups above, there are other professionals such as engineers, mechanical contractors, chemists, registered sanitarians, and microbiologists, for example, who perform indoor air quality investigations. The public is advised to consult local yellow page listings under “Environmental and Ecological Consultants,” or “Environmental and Ecological Equipment and Services,” for other consultants in this field. Internet searches may also be helpful.
