protection in occupational settings.
2. What is the primary health risk associated with asbestos exposure?
A) Skin rash
B) Lung cancer and mesothelioma
C) Hearing loss
D) Vision problems
, Rationale: Inhalation of asbestos fibers can cause lung cancer,
mesothelioma, and asbestosis.
3. What type of respirator is typically required for asbestos abatement?
A) Surgical mask
B) NIOSH-approved P100 respirator
C) Cloth mask
D) Dust mask
Rationale: P100 respirators filter out 99.97% of airborne asbestos
fibers.
4. Which method is safest for removing friable asbestos?
A) Dry scraping
B) Wet removal
C) Sanding
D) Chipping
Rationale: Wet methods reduce airborne fiber release during
removal of friable asbestos.
5. What does friable asbestos mean?
A) Bound in cement
B) Easily crumbled or powdered by hand
C) Non-hazardous
D) Asbestos insulation only
Rationale: Friable asbestos can release fibers into the air easily,
posing higher health risks.
,6. How often should asbestos workers undergo medical surveillance?
A) Once a decade
B) Every 5 years
C) Only if symptoms appear
D) Annually
Rationale: OSHA requires annual medical examinations for workers
exposed to asbestos.

B) Heat the work area
C) Remove water
D) Increase ventilation for workers
Rationale: NAPUs maintain negative pressure to keep contaminated
air from leaving the containment area.
10. How should asbestos waste be transported?
A) In open containers
B) In leak-tight, labeled containers
C) Mixed with regular trash
D) In cardboard boxes
Rationale: OSHA and EPA require asbestos waste to be sealed,
labeled, and handled carefully to prevent fiber release.
11. Which of the following PPE is required during asbestos
abatement?
A) Safety shoes only
B) Gloves only
C) Full protective clothing, gloves, and respirator
