AHERA requires inspections and management plans for asbestos in schools.
2. The term "PACM" refers to:
A. Potential airborne contaminant material
B. Presumed Asbestos-Containing Material
C. Planned asbestos contamination management
D. Processed asbestos cement material
PACM applies to TSI and surfacing materials in pre-1981 buildings unless proven
otherwise.
3. Which of the following is NOT a Class I asbestos work activity?
A. Removal of non-friable floor tiles
B. Removal of thermal system insulation
C. Encapsulation of spray-applied insulation
D. Enclosure of friable surfacing material
Class I involves removal of TSI or surfacing ACM. Non-friable floor tiles are Class II.
4. Which agency regulates airborne asbestos emissions during demolition?
A. OSHA
, B. AHERA
C. EPA/NESHAP
D. Cal/OSHA
NESHAP regulates asbestos emissions during demolition and renovation.

A. 0.2 f/cc
B. 0.1 f/cc
C. 1.0 f/cc
D. 0.01 f/cc
PEL = 0.1 fibers/cc averaged over 8 hours.
6. How long must records of employee asbestos exposure monitoring be kept?
A. 10 years
B. For the duration of employment
C. 30 years
D. 5 years
Exposure monitoring records must be kept 30 years.

A. Polarized Light Microscopy (PLM)
B. Transmission Electron Microscopy (TEM) only
C. Phase Contrast Microscopy (PCM)
D. Scanning Electron Microscopy (SEM)
PLM is the EPA-approved method for bulk samples.
8. Which asbestos fiber type is most commonly found in building materials in the U.S.?
A. Amosite
B. Crocidolite
C. Chrysotile
D. Tremolite
Chrysotile (white asbestos) accounts for ~90–95% of asbestos in U.S. buildings.

Continuing 10–120
, 10. Which method is commonly used to evaluate airborne asbestos fibers during
clearance monitoring?
A. PLM
B. PCM
C. TEM for bulk samples
D. SEM
Phase Contrast Microscopy is used for air clearance monitoring; TEM may be used for
stricter criteria.
11. Friable asbestos-containing material is defined as:
A. Any asbestos material used before 1970
B. Material that can be crumbled by hand pressure when dry
C. Asbestos material with >10% asbestos
D. Cement-based material only
Friable ACM can be easily crumbled when dry, releasing fibers.
12. The initial determination of asbestos exposure levels for a project is called:
A. Clearance testing
B. Competent person evaluation
C. Negative exposure assessment
D. Baseline clearance study
A negative exposure assessment establishes that employee exposure will be below
PELs.
13. Which asbestos regulation focuses on demolition and renovation activities?
A. AHERA
B. OSHA 1910.1001
C. EPA NESHAP
D. ASHARA
NESHAP regulates demolition/renovation to control asbestos emissions.
14. Which asbestos-related disease is characterized by lung scarring?
A. Mesothelioma
B. Lung cancer
C. Asbestosis
D. Asthma
Asbestosis is chronic lung scarring caused by asbestos exposure.
15. Which of the following fibers is classified as amphibole asbestos?
