The Premier Directory of Industrial Hygiene and Occupational and Environmental Health and Safety Consulting Professionals

Welcome to the AIHA Consultants Listing—a trusted name that consumers and professionals turn to for accurate and dependable information about industrial hygiene and occupational and environmental health and safety consultants.

Since 1979, AIHA has produced and distributed the Consultants Listing, a searchable print and online directory of its consultant members. This listing is the leading directory of industrial hygiene (IH/OEHS) and other occupational and environmental health and safety (OEHS) consultants. It is available to anyone to use FREE of charge. Government agencies such as EPA, FEMA, and OSHA regularly refer consumer inquires to our consultants for assistance. AIHA’s Consultants Listing is also frequently referenced as a media source for consumers when searching for an IH/OEHS or OEHS consultant.
