SECTION I: REGULATORY STANDARDS & EXPOSURE LIMITS
• 1. What is the OSHA Permissible Exposure Limit (PEL) for 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)
Rationale: The OSHA PEL for asbestos is 0.1 f/cc as an 8-hour TWA, representing the maximum
average airborne concentration to which workers may be exposed over an 8-hour work shift.
• 2. 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
Rationale: The OSHA Excursion Limit is 1.0 f/cc measured over a 30-minute sampling period,
representing the maximum concentration allowed during any 30-minute period of the work
shift.
• 3. Which regulation covers asbestos standards for the construction industry?
A) 29 CFR 1910.1001
•• B) 29 CFR 1926.1101 ••
C) 40 CFR Part 763
D) 29 CFR 1910.1200
Rationale: 29 CFR 1926.1101 is the OSHA asbestos standard specifically for the construction
industry. 29 CFR 1910.1001 covers general industry, while 40 CFR Part 763 addresses EPA
requirements for schools (AHERA).
• 4. Which regulation is associated with the EPA Asbestos Hazard Emergency Response Act
(AHERA)?

Rationale: 40 CFR Part 763 contains the EPA's AHERA regulations, which govern asbestos
management in schools, including inspection, reinspection, and response actions.
• 5. 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
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.

A) 0.01 f/cc
•• B) 0.05 f/cc ••
C) 0.1 f/cc
D) 1.0 f/cc
Rationale: The OSHA Action Level for asbestos is 0.05 f/cc as an 8-hour TWA. This is the
concentration that triggers certain compliance requirements such as medical surveillance and
exposure monitoring.
• 7. Which OSHA standard governs asbestos exposure in general industry?
•• A) 29 CFR 1910.1001 ••
B) 29 CFR 1926.1101
C) 29 CFR 1910.1200
D) 29 CFR 1910.1000
Rationale: OSHA's general-industry asbestos standard is 29 CFR 1910.1001; the construction
standard is 29 CFR 1926.1101.
, • 8. Which OSHA standard covers asbestos in shipyard employment?
A) 29 CFR 1910.1001
•• B) 29 CFR 1915.1001 ••
C) 29 CFR 1926.1101
D) 40 CFR 763
Rationale: The shipyard asbestos standard is 29 CFR 1915.1001, which addresses occupational
exposure to asbestos in shipyard employment.
• 9. What is the MSHA standard for asbestos in mines?
A) 29 CFR 1910.1001
•• B) 30 CFR Part 56 and 57 ••
C) 40 CFR Part 763
D) 42 USC 7401
Rationale: MSHA (Mine Safety and Health Administration) has asbestos standards in 30 CFR
Part 56 and 57 for metal and nonmetal mines.
• 10. What is the estimated limit of detection (LOD) for NIOSH Method 7400?
A) 5 fibers/mm²
B) 6 fibers/mm²
•• C) 7 fibers/mm² ••
D) 10 fibers/mm²
Rationale: The estimated limit of detection for NIOSH Method 7400 is 7 fibers per square
millimeter (f/mm²) of filter surface area.
• 11. What is the upper limit of the optimal fiber density range for NIOSH 7400?
A) 100 fibers/mm²
B) 500 fibers/mm²
C) 1000 fibers/mm²
•• D) 1300 fibers/mm² ••
