Introduction
This comprehensive examination preparation guide is designed for professionals seeking NIOSH
582 certification in "Sampling and Evaluating Airborne Asbestos Dust." The course provides in-
depth training on the NIOSH 7400 analytical method using Phase Contrast Microscopy (PCM) for
the quantification of airborne asbestos fibers. Candidates must demonstrate competency in
sampling equipment calibration, microscope alignment and calibration, sample preparation and
mounting, application of counting rules, quality assurance/quality control procedures, and
sampling-related mathematics. The multiple-choice and scenario-based structure of this guide
emphasizes real-world application, regulatory compliance, and analytical precision required for
occupational exposure monitoring. Each question is crafted to reflect the content and rigor of
the actual NIOSH 582 final examination, ensuring candidates are well-prepared for certification
success. This resource is updated to reflect the latest OSHA, EPA, and NIOSH regulatory
requirements for the 2025/2026 exam cycle.

reinspection, and response actions.
4. What is the current OSHA Permissible Exposure Limit (PEL) for airborne asbestos as an 8-
hour Time-Weighted Average (TWA)?
A. 0.01 fibers per cubic centimeter (f/cc)
B. 0.1 fibers per cubic centimeter (f/cc)
C. 1.0 fibers per cubic centimeter (f/cc)
D. 10 fibers per cubic centimeter (f/cc)
B. 0.1 fibers per cubic centimeter (f/cc)
RATIONALE: The OSHA PEL for asbestos is 0.1 fibers per cubic centimeter (f/cc) as an 8-hour
TWA. This is the maximum average airborne concentration to which workers may be exposed
over an 8-hour work shift.
5. What is the OSHA Excursion Limit (EL) for asbestos exposure?
, A. 0.1 f/cc over 15 minutes
B. 0.5 f/cc over 30 minutes
C. 1.0 f/cc over 30 minutes
D. 5.0 f/cc over 15 minutes
C. 1.0 f/cc over 30 minutes
RATIONALE: The OSHA Excursion Limit is 1.0 f/cc measured over a 30-minute sampling
period. This represents the maximum concentration allowed during any 30-minute period of the
work shift.
6. Which standard specifies the air sampling method for asbestos fiber counting?
A. OSHA ID-160
B. NIOSH 7400
C. EPA 600/4-78
D. ASTM D7200
B. NIOSH 7400
RATIONALE: NIOSH 7400 is the standard analytical method for sampling and evaluating
airborne asbestos fibers using Phase Contrast Microscopy (PCM). This method forms the basis
of the NIOSH 582 course curriculum.
7. What type of microscope is used to count airborne asbestos fibers according to the NIOSH
7400 method?
A. Brightfield microscope
B. Phase contrast microscope
C. Scanning electron microscope
D. Transmission electron microscope
B. Phase contrast microscope
RATIONALE: Phase contrast microscopy (PCM) is the method specified by NIOSH 7400 for
counting airborne asbestos fibers. PCM enhances the contrast of transparent fibers, making
them visible against the background.
8. What is the total magnification required for a PCM microscope used for airborne asbestos
counting?
