1. Which of the following is a common method for identifying asbestos in
building materials?
A. Visual inspection only
B. Polarized Light Microscopy (PLM)
C. X-ray diffraction without sample preparation
D. Infrared spectroscopy without sampling
Rationale: PLM is the standard analytical method for identifying asbestos
fibers in bulk materials according to EPA and OSHA guidelines.
2. Asbestos is most hazardous when:
A. It is intact and undisturbed
B. Fibers become airborne and are inhaled
,C. It is wet and encapsulated
D. It is covered by paint
Rationale: Asbestos is dangerous primarily when fibers are released into
the air and inhaled, which can cause lung diseases.
3. Which federal agency regulates asbestos in schools and commercial
buildings?
A. FDA
B. EPA
C. CDC
D. OSHA
Rationale: The Environmental Protection Agency (EPA) regulates asbestos
in schools under AHERA (Asbestos Hazard Emergency Response Act).
4. What is the first step in conducting an asbestos inspection?
A. Collecting samples immediately
B. Conducting a site survey and reviewing building plans
C. Sending bulk samples to the lab
D. Removing suspect materials
Rationale: Inspectors must perform a visual survey and review building
documentation to plan safe sampling.
5. Which type of asbestos fiber is the most common in building materials?
A. Crocidolite
B. Amosite
,C. Chrysotile
D. Tremolite
Rationale: Chrysotile (white asbestos) is the most widely used type in
construction materials.
6. Which of the following is a friable asbestos-containing material (ACM)?
A. Vinyl floor tiles
B. Roofing shingles
C. Spray-applied insulation
D. Cement siding
Rationale: Friable ACM can be crumbled by hand and release fibers,
making spray-applied insulation highly hazardous.
7. What personal protective equipment (PPE) is required for sampling
asbestos?
A. Gloves only
B. Safety glasses only
C. Respirator, disposable coveralls, gloves
D. Hard hat only
Rationale: Sampling requires full PPE to prevent inhalation and
contamination of clothing.
8. Which OSHA regulation governs worker exposure to asbestos?
A. 29 CFR 1910.134
B. 29 CFR 1926.1101
, C. 40 CFR Part 763
D. 29 CFR 1910.1200
Rationale: OSHA’s construction standard 29 CFR 1926.1101 covers asbestos
exposure for workers.
9. The AHERA regulation requires re-inspections of asbestos-containing
school buildings every:
A. 3 years
B. 3 years for full inspections, 6 months for surveillance
C. 1 year
D. 5 years
Rationale: AHERA mandates periodic inspections and surveillance to
monitor ACM condition in schools.
10. Which type of asbestos analysis is required for air samples?
A. PLM
B. X-ray diffraction
C. Transmission Electron Microscopy (TEM)
D. Polarization spectroscopy
Rationale: TEM is used for airborne asbestos because it can detect very
small fibers that PLM cannot.
11. What is the purpose of using a HEPA vacuum during asbestos cleanup?
A. General dust removal
B. Floor polishing
