2025|2026 Q&A | Instant Download Pdf
1. What is the primary purpose of an asbestos project design?
a) To reduce labor costs
b) To outline abatement procedures and ensure compliance with
regulations
c) To maximize speed of removal
d) To minimize use of protective equipment
b) To outline abatement procedures and ensure compliance with
regulations
Rationale: The design ensures regulatory compliance, safety, and
efficiency, not cost savings or shortcuts.
2. Which federal agency sets standards for worker exposure to asbestos
in the workplace?
, a) EPA
b) OSHA
c) NIOSH
d) CDC
Rationale: OSHA sets permissible exposure limits and worker
protection standards.
3. Which EPA regulation governs asbestos in schools and public
buildings?
a) NESHAP
b) AHERA
c) TSCA Title VI
d) RCRA
Rationale: AHERA (Asbestos Hazard Emergency Response Act)
applies to schools and public facilities.
4. What is the permissible exposure limit (PEL) for asbestos under OSHA?
a) 0.5 f/cc as 8-hour TWA
b) 0.1 f/cc as 8-hour TWA
c) 1.0 f/cc as 8-hour TWA
d) 0.05 f/cc as 8-hour TWA
Rationale: OSHA PEL is 0.1 fibers per cubic centimeter averaged over
8 hours.
5. Which of the following asbestos types is most commonly used in the
U.S.?
, a) Amosite
b) Crocidolite
c) Chrysotile
d) Tremolite
Rationale: Chrysotile accounts for over 90% of asbestos used
historically in the U.S.
6. Friable asbestos-containing material is defined as a material that:
a) Cannot be pulverized by hand pressure
b) Can be crumbled or reduced to powder by hand pressure
c) Is used only in sprayed-on coatings
d) Is present in pipe insulation only
Rationale: Friable means easily crumbled to release fibers.
7. The main health effect of asbestos exposure is:
a) Lung cancer only
b) Asthma
c) Skin rashes
d) Asbestosis, mesothelioma, and lung cancer
Rationale: Asbestos causes asbestosis, mesothelioma, and cancers.
8. Under NESHAP, how much regulated asbestos-containing material
(RACM) triggers notification requirements for renovation?
a) 10 linear feet or 5 square feet
b) 100 linear feet or 50 square feet
c) 260 linear feet or 160 square feet
, d) 500 linear feet or 300 square feet
Rationale: The threshold for notification under NESHAP is 260 LF or
160 SF of RACM.
9. Which document must the project designer prepare before asbestos
abatement?
a) Employee payroll list
b) Emergency evacuation plan only
c) Project specifications and design documents
d) Worker medical records
Rationale: The designer produces project specifications including
procedures, safety, and disposal requirements.
10. Which air sampling method is most commonly used for asbestos
fibers?
a) Gas chromatography
b) Scanning electron microscopy
c) Atomic absorption spectroscopy
d) Phase contrast microscopy (PCM)
Rationale: PCM is standard for regulatory compliance air monitoring.
11. The OSHA standard requires which type of respirator for workers
exposed above the PEL during asbestos removal?
a) Half-mask air-purifying respirator with dust filter
b) Surgical mask
