1. What are the three primary fatal diseases linked directly to
asbestos exposure?
• A) Diabetes, asthma, and bronchitis
• B) Asbestosis, mesothelioma, and lung cancer
• C) Malaria, yellow fever, and cholera
• D) Dermatitis, carpal tunnel, and tendonitis
• Answer: B
• Rationale: Inhaling asbestos fibers causes pulmonary
fibrosis (asbestosis), pleural/peritoneal cancer
(mesothelioma), and bronchogenic carcinoma (lung
cancer).
2. What does the acronym HEPA stand for in asbestos
abatement equipment?
• A) High-Energy Particle Absorber
• B) Hazardous Environmental Protection Apparatus
• C) High-Efficiency Particulate Air
• D) Heavy-Duty Exhaust Purification Assembly
, • Answer: C
• Rationale: HEPA refers to high-efficiency particulate air
filtration standards capable of trapping microscopic
asbestos fibers.
3. What is the primary purpose of using "wet methods" during
the removal of asbestos-containing materials?
• A) To cool down power tools
• B) To suppress and prevent asbestos fibers from becoming
airborne
• C) To speed up the drying time of plaster
• D) To reduce the weight of waste bags
• Answer: B
• Rationale: Water with a wetting agent binds to fibers,
keeping materials damp and preventing them from
releasing into the air during handling.
4. According to OSHA standards, what is the Permissible
Exposure Limit (PEL) for airborne asbestos over an 8-hour
time-weighted average (TWA)?
• A) 1.0 fiber per cubic centimeter (f/cc)
• B) 0.5 fiber per cubic centimeter (f/cc)
• C) 0.1 fiber per cubic centimeter (f/cc)
, • D) 5.0 fibers per cubic centimeter (f/cc)
• Answer: C
• Rationale: OSHA sets the strict 8-hour TWA PEL at 0.1 f/cc
to protect workers from chronic inhalation hazards.
5. What is the OSHA Excursion Limit for asbestos exposure
over a 30-minute sampling period?
• A) 0.1 f/cc
• B) 0.5 f/cc
• C) 1.0 f/cc
• D) 5.0 f/cc
• Answer: C
• Rationale: The excursion limit caps short-term exposure at
1.0 f/cc over any continuous 30-minute measurement
window.
6. What minimum efficiency rating must HEPA filters maintain
when capturing particles down to 0.3 microns?
• A) 90.0%
• B) 95.5%
• C) 99.97%
• D) 100% absolute with no tolerance
, • Answer: C
• Rationale: Industrial HEPA filters are tested and certified to
capture at least 99.97% of 0.3-micron particles.
7. Why is compressed air strictly prohibited for cleaning
asbestos-contaminated clothing or work surfaces?
• A) It consumes too much electricity.
• B) It aerosolizes settled asbestos fibers, turning them into
breathable airborne dust.
• C) It ruins the air compressor motor.
• D) It makes too much noise.
• Answer: B
• Rationale: Using compressed air blasts settled fibers back
into the air, creating a severe inhalation hazard for anyone
in the area.
8. What type of respirator is commonly required for workers
inside a high-exposure asbestos containment area?
• A) A loose-fitting paper dust mask
• B) A tight-fitting full-face or half-mask air-purifying
respirator with HEPA cartridges (P100), or a Powered Air-
Purifying Respirator (PAPR)
• C) A standard surgical mask
