1. The main federal regulation governing asbestos in the workplace
is:
A) Clean Air Act
B) Resource Conservation and Recovery Act
C) OSHA Asbestos Standards
D) National Fire Protection Association
OSHA sets standards for asbestos exposure in the workplace to protect
worker safety.
2. The permissible exposure limit (PEL) for asbestos fibers in the air
for an 8-hour work shift is:
A) 1 fiber/cc
B) 0.1 fiber/cc
C) 0.5 fiber/cc
D) 5 fibers/cc
OSHA’s PEL for asbestos is 0.1 fibers per cubic centimeter of air as an 8-
hour TWA.
3. What type of respirator is required for handling friable asbestos
materials?
, A) Half-mask with dust filter
B) Full-face HEPA respirator
C) Powered air-purifying respirator (PAPR) without filter
D) No respirator required
A full-face HEPA respirator ensures maximum protection from airborne
asbestos fibers.
4. The primary route of asbestos exposure that leads to health risks
is:
A) Ingestion
B) Inhalation
C) Skin contact
D) Eye contact
Inhalation of asbestos fibers can lead to serious diseases such as
asbestosis and mesothelioma.
5. Which of the following is considered friable asbestos-containing
material?
A) Vinyl floor tiles
B) Sprayed-on insulation
C) Asphalt roofing
D) Window caulking
Friable asbestos materials can be easily crumbled by hand, releasing
fibers into the air.
6. Before beginning abatement, a worker must:
A) Take a short training course
B) Complete proper asbestos awareness and abatement training
C) Buy personal protective equipment only
D) Notify neighbors
, Proper training ensures workers understand hazards and safe handling
procedures.
7. Wetting asbestos materials before removal is recommended
because:
A) It makes the material lighter
B) It reduces airborne fiber release
C) It neutralizes toxins
D) It prevents asbestos from sticking to tools
Moisture suppresses fiber release during removal and reduces
inhalation risk.
8. The critical layer for containing asbestos during abatement is:
A) Interior walls
B) Negative-pressure enclosure
C) Protective gloves
D) Roof ventilation
Negative-pressure enclosures prevent fibers from escaping the work
area.
9. HEPA filters are effective because they can trap:
A) Large dust particles only
B) Asbestos fibers as small as 0.3 microns
C) Only water vapor
D) Smoke particles only
HEPA filters capture very fine asbestos fibers to prevent contamination.
10. After removing asbestos, all waste must be:
A) Burned on-site
B) Double-bagged and labeled for disposal at a licensed facility
C) Stored indefinitely in the building
D) Mixed with soil
