COURSE OUTLINE & SYLLABUS
Course schedule: 8:00 a.m. – 5:00 p.m. Monday – Thursday, and 8:00 a.m. – 12:00 p.m. Friday
This is the NIOSH 582 course: “Sampling and Evaluating Airborne Asbestos Dust.”
The NIOSH 7400 method using phase contrast microscopy (PCM) is detailed, including QA/QC procedures, statistics, and sampling-related mathematics.
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.
