1. Which of the following is the primary health hazard associated with asbestos
exposure?
A) Lung cancer
B) Asthma
C) Skin irritation
D) Cardiovascular disease
Answer: A) Lung cancer
Rationale: Asbestos exposure is primarily associated with lung cancer, as well as mesothelioma
and asbestosis. These diseases develop due to the inhalation of asbestos fibers.
2. Asbestos-containing materials (ACMs) are considered hazardous if:
A) They are in good condition
B) They release fibers when disturbed
C) They are painted
D) They are not visible to the naked eye
Answer: B) They release fibers when disturbed
Rationale: ACMs are hazardous primarily because they release airborne fibers when disturbed,
which can be inhaled and cause health problems.
3. Which of the following is an appropriate method for sampling asbestos-
containing material during an inspection?
A) Using a handheld vacuum
B) Wetting the material and taking a bulk sample
C) Scraping the material with a screwdriver
D) Using a dry brush to collect samples
Answer: B) Wetting the material and taking a bulk sample
Rationale: Wetting the material helps to reduce the release of fibers, and bulk sampling is the
most reliable method to analyze asbestos content.
4. What is the most effective way to prevent asbestos exposure during an
inspection?
,A) Wearing gloves and a lab coat
B) Using a respirator with an HEPA filter
C) Avoiding physical contact with materials
D) Using a face shield
Answer: B) Using a respirator with an HEPA filter
Rationale: A respirator with a high-efficiency particulate air (HEPA) filter is necessary to
protect inspectors from inhaling airborne asbestos fibers during an inspection.
5. Asbestos is most commonly found in which of the following building
materials?
A) Insulation
B) Sheetrock
C) Concrete
D) Plywood
Answer: A) Insulation
Rationale: Asbestos is most commonly found in insulation materials, especially in older
buildings, as it was used for its fire resistance and insulating properties.
6. Which of the following is a key characteristic of friable asbestos-containing
material (ACM)?
A) It is hard and rigid
B) It can be easily crumbled, pulverized, or reduced to powder
C) It is not a health risk
D) It is highly resistant to damage
Answer: B) It can be easily crumbled, pulverized, or reduced to powder
Rationale: Friable ACMs can release asbestos fibers easily when disturbed, making them a
significant health risk.
7. What is the primary purpose of the National Emission Standards for
Hazardous Air Pollutants (NESHAP) regulations?
A) To limit the amount of asbestos in building materials
B) To control the demolition and renovation of buildings containing asbestos
, C) To regulate the disposal of asbestos-containing materials
D) To enforce penalties for non-compliance with asbestos regulations
Answer: B) To control the demolition and renovation of buildings containing asbestos
Rationale: NESHAP regulations focus on controlling asbestos emissions during demolition and
renovation activities to prevent the release of fibers into the air.
8. What is the minimum fiber concentration in air that is considered hazardous
for workers according to OSHA standards?
A) 0.01 fibers per cubic centimeter (f/cc)
B) 0.1 fibers per cubic centimeter (f/cc)
C) 1.0 fibers per cubic centimeter (f/cc)
D) 10 fibers per cubic centimeter (f/cc)
Answer: A) 0.01 fibers per cubic centimeter (f/cc)
Rationale: OSHA sets the permissible exposure limit for asbestos at 0.1 f/cc, and exposure
above this threshold is considered hazardous for workers.
9. During an asbestos inspection, which of the following is NOT recommended?
A) Using high-efficiency particulate air (HEPA) vacuums to clean up asbestos debris
B) Keeping the area well-ventilated to avoid dust buildup
C) Wearing personal protective equipment (PPE) like disposable coveralls
D) Using a brush to sweep up asbestos fibers without wetting the area
Answer: D) Using a brush to sweep up asbestos fibers without wetting the area
Rationale: Sweeping without wetting the area can stir up asbestos fibers, creating airborne
hazards. It is essential to wet materials to minimize fiber release.
10. Which of the following actions should be taken if asbestos-containing
materials are found in a building?
A) Immediately remove all materials
B) Monitor the materials regularly for deterioration
C) Cover the materials with plastic sheeting
D) Ignore the materials if they are undisturbed
exposure?
A) Lung cancer
B) Asthma
C) Skin irritation
D) Cardiovascular disease
Answer: A) Lung cancer
Rationale: Asbestos exposure is primarily associated with lung cancer, as well as mesothelioma
and asbestosis. These diseases develop due to the inhalation of asbestos fibers.
