Assessor Technical Training: Asbestos


This course provides examples of the assessment process for asbestos testing laboratory technologies, based on The NELAC Institute (TNI) Environmental Laboratory Standard 2009. The principles for assessing specific technical disciplines within the laboratory operations are presented. The course presents the fundamentals of how to assess technical operations for the following technologies:

Polarized Light Microscopy (PLM)
Phase Contract Microscopy (PCM)
Transmission Electron Microscopy (TEM)

The rationale for assessing is based on proven quality principals that allow the determination of adherence to the defined system for the technical operations. The system standards used during this course are the 2009 TNI Environmental Laboratory (EL) standard. Personnel with a basic science background in this technical area assess operations by conducting an assessment of a laboratory system and technical operations to assure conformance to the stated management system and where applicable the mandated methods.

Personnel successfully completing the course will acquire the following:

  • Knowledge sufficient to assess the implementation of the technology by the laboratory.
  • An understanding of the key elements of data packages, and raw data to review and check effectively.
  • How to write non-conformances and track corrective actions, evaluate root cause analysis and evaluate the effectiveness of the implementation.

Final Exam

  • Students should prepare for the final exam prior to taking the class.
  • Students must read TNI EL Volumes 1 and 2.
  • Students are expected to be thoroughly familiar with the technology and standard before taking the class. You must obtain a 70% score to "successfully complete" the course. (NELAP assessors: You may be required to have successfully completed technical assessor-training. The NELAP assessor qualifications are defined by each accreditation body.)
  • All students receive a certificate of course attendance if attending the webinar and not successfully completing the test or turning in the class exercises. Students with test scores of greater than or equal to 70% receive a certificate of course completion.
