1. What is the primary purpose of an asbestos inspection?
A. To remove asbestos immediately
B. To locate and assess ACMs
C. To prepare air monitoring reports
D. To supervise abatement contractors
Rationale: Inspectors identify and assess asbestos-containing materials,
not remove them.
2. Which federal regulation requires asbestos inspections in K-12 schools?
A. CERCLA
B. AHERA
C. NESHAP
D. TSCA
Rationale: The Asbestos Hazard Emergency Response Act (AHERA)
mandates school inspections.
3. Asbestos fibers are most hazardous when:
A. Intact and undisturbed
B. Airborne and inhaled
C. Covered with paint
D. Wet and encapsulated
Rationale: Only airborne fibers pose significant inhalation risk.
4. A friable asbestos material is defined as one that:
A. Has less than 1% asbestos
, B. Is non-hazardous
C. Can be crumbled by hand pressure
D. Cannot be sampled
Rationale: Friability refers to ease of crumbling and fiber release.
5. Which type of asbestos fiber is most common in buildings?
A. Crocidolite
B. Amosite
C. Chrysotile
D. Tremolite
Rationale: Chrysotile (white asbestos) is the most prevalent in
construction materials.
6. What is the usual analytical method for identifying asbestos in bulk
samples?
A. TEM
B. PLM
C. PCM
D. XRF
Rationale: Polarized Light Microscopy (PLM) is standard for bulk material
identification.
7. The OSHA regulation that governs asbestos exposure in construction is:
A. 29 CFR 1910.134
B. 29 CFR 1926.1101
C. 40 CFR 763
D. 29 CFR 1910.1200
Rationale: 29 CFR 1926.1101 covers asbestos for construction workers.
8. Which sample type confirms asbestos content in material?
A. Air sample
B. Bulk sample
C. Wipe sample
D. Personal sample
Rationale: Bulk samples determine the composition of suspect material.
9. Clearance air sampling is performed:
A. Before inspection
, B. After abatement
C. During sample collection
D. Only for floor tiles
Rationale: Clearance sampling verifies safety post-abatement.
10.PACM stands for:
A. Prescribed ACM
B. Potential ACM
C. Presumed Asbestos-Containing Material
D. Primary ACM
Rationale: PACM is used when ACM is assumed present due to age/type.
11.What PPE should an inspector wear when sampling friable ACM?
A. Gloves only
B. Safety glasses
C. Respirator and disposable coveralls
D. Hard hat only
Rationale: Full PPE prevents inhalation and contamination.
12.Minimum number of bulk samples for a homogeneous area of surfacing
material ≤ 1000 sq ft is:
A. 1
B. 2
C. 3
D. 5
Rationale: EPA/AHERA guidelines require at least 3 samples.
13.Homogeneous area is:
A. Any room
B. Area of same material/condition
C. Only friable materials
D. Exterior only
Rationale: Defined by uniform materials with identical characteristics.
14.Asbestos is classified as a:
A. Synthetic plastic
B. Organic compound
C. Naturally occurring fibrous mineral
