GLENDALE, Ariz. - The American Board of Industrial Hygiene (ABIH) has recognized certain American Indoor Air Quality Council certifications in its Certified Industrial Hygienist (CIH) certification maintenance program.

Any CIH who now earns the Council-certified Indoor Environmental Consultant (CIEC) designation or the Council-certified Microbial Consultant (CMC) designation will receive 2.5 certification maintenance points toward recertification as a CIH.

“Industrial hygiene and indoor air quality have always been closely related,” said Charlie Wiles, IAQ Council executive director. “This announcement confirms that relationship and helps to establish IAQ Council certifications as the standard for our industry.”

Wiles noted that many CIECs and CMCs hold the CIH designation and predicted that many more will take advantage of the new program.

“It is entirely appropriate that our certificants be recognized for holding the only accredited certifications in the IAQ industry,” he said.

The American Indoor Air Quality Council is a nonprofit certifying body founded in 1993 to serve the IAQ industry. It operates independent, third-party accredited certification programs for indoor environmental consultants, microbial consultants, microbial remediators, indoor air quality administrators, and residential mold inspectors.
