This is the NIOSH 582 course: “Sampling and Quantitating Airborne Asbestos Dust.”

The NIOSH 7400 method, using phase contrast microscopy (PCM), is detailed, including means for QA/QC procedures.

At the conclusion of the course, students are able to: properly calibrate and use the sampling equipment; align and calibrate the microscope and apply the NIOSH 7400 protocols; prepare samples for analysis; and apply the procedures for collection and quantitation of ambient dust samples.

Practical field-related problems are discussed.
