The Asbestos Analysts Testing program is the proficiency testing program for the Asbestos Analysts Registry. It is designed for individual asbestos analysts performing fiber-counting of membrane filters by phase contrast microscopy on the job site. Samples are provided on a quarterly basis with the opportunity for the analyst to override his/her scores by participating in the retest round. Asbestos samples are generated and distributed by SRI International, with data analysis performed by the AIHA Registry Programs, LLC.
Who should participate in the AAT Program?
Analysts who perform fiber counting procedures at the job site need assurance of the quality of their work, which can be provided by this program through adherence to the AAR program requirements. Analysts who desire to be listed in the AAR must participate in the AAT. Proficient performance is a requirement for recognition as an AAR board approved analyst.
Who can participate in the AAT?
The AAT Program is the proficiency testing program for fiber counting analysts who desire to be listed on the Asbestos Analysts Registry (AAR). Only analysts enrolled in the AAR may participate in the AAT program.
How does the AAT program work?
When an organization enrolls in the AAR Program each of their registered analysts are enrolled in the AAT program. Analysts can also be added to the enrollment of an approved organization. Every analyst is assigned a unique ID number that is used with the organization ID number to enter their results into the AAT Data Entry portal. Samples are shipped quarterly to the organization's AAT contact. One sample kit can be analyzed up to five analysts. Sample analysis must be performed using the latest version of the NIOSH 7400 method for counting fibers. Analytical procedures must be in compliance with the OSHA asbestos standard, 29 CFR 1910.1001.
