1. What is the primary purpose of an asbestos inspection?
A. To remove asbestos-containing materials (ACM)
B. To identify and assess asbestos-containing materials
C. To enforce OSHA standards
D. To clean and maintain buildings
B. To identify and assess asbestos-containing materials
The inspector’s role is to identify suspect ACM and evaluate its condition, not remove
or enforce.
2. Under AHERA, which buildings are required to have an asbestos inspection?
A. Private homes
B. All public and commercial buildings
C. Public and private schools K–12
D. Industrial facilities only
C. Public and private schools K–12
AHERA mandates inspections in schools to protect children and staff.
3. Which federal regulation defines asbestos as a hazardous air pollutant?
A. AHERA
B. NESHAP
C. TSCA
D. OSHA 1926.1101
B. NESHAP
NESHAP under the Clean Air Act classifies asbestos as a hazardous air pollutant.
,4. Friable asbestos is best defined as:
A. ACM that is easily crumbled by hand pressure
B. ACM that is solid and intact
C. ACM sealed with encapsulant
D. ACM submerged in water
A. ACM that is easily crumbled by hand pressure
Friability indicates potential fiber release into the air.
5. Which of the following is considered a surfacing material?
A. Pipe insulation
B. Spray-applied fireproofing
C. Floor tile
D. Roofing material
B. Spray-applied fireproofing
Surfacing materials include spray-applied and troweled-on applications.
6. What is the role of the inspector when suspect ACM is found?
A. Immediately abate the ACM
B. Collect bulk samples for laboratory analysis
C. Encapsulate the ACM
D. Notify OSHA directly
B. Collect bulk samples for laboratory analysis
The inspector’s responsibility is to confirm asbestos presence via sampling.
7. Which laboratory method is most commonly used to analyze bulk samples?
A. PCM
B. TEM
C. PLM
D. XRF
C. PLM
Polarized Light Microscopy (PLM) is the standard method for bulk analysis.
8. When sampling floor tile for asbestos, what must also be collected?
A. Carpet backing
B. Subfloor adhesive (mastic)
C. Concrete slab
D. Ceiling tile
B. Subfloor adhesive (mastic)
Mastics can contain asbestos even if the tile does not.
9. What is the minimum number of samples required under AHERA for surfacing
material in a homogeneous area less than 1,000 square feet?
A. 3
, B. 5
C. 7
D. 9
A. 3
AHERA specifies at least 3 samples for small homogeneous areas.
10. Which EPA regulation requires accredited inspectors for asbestos inspections?
A. NESHAP
B. AHERA
C. OSHA 1910.1001
D. CERCLA
B. AHERA
AHERA established accreditation requirements for asbestos inspectors.
11. What type of asbestos was most commonly used in thermal system insulation?
A. Chrysotile
B. Crocidolite
C. Amosite
D. Tremolite
C. Amosite
Amosite (brown asbestos) was frequently used in insulation products.
12. What should an inspector do before collecting a bulk sample?
A. Wet the material
B. Apply encapsulant
C. Remove all surrounding materials
D. Cut a large section
A. Wet the material
Wetting reduces the potential for fiber release.
13. What is a homogeneous area?
A. An area where all ACM is friable
B. An area with uniform color, texture, and material type
C. An area larger than 1,000 square feet
D. An area where ACM is encapsulated
B. An area with uniform color, texture, and material type
Homogeneous areas are sampled based on material similarity.
14. Which sampling strategy reduces inspector bias?
A. Sampling only damaged material
B. Sampling from areas most accessible
C. Random sampling
D. Sampling only visually different areas
