Asbestos Analysts Registry

The Asbestos Analysts Registry (AAR) program, offered by the AIHA Registry Programs, was designed to recognize the analysts of organizations involved in fiber counting on air samples outside of established laboratory locations, primarily on the job site or in the field, but is also used by laboratory locations that desire documentation of their ability to do quality work, but that are not required by federal or state regulations to be accredited.
