Asbestos Fiber Counting [NIOSH 582] (1616), March 17–21, 2025 In-Person
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.
