1. Which of the following materials is classified under Class II
asbestos-containing materials?
A. Spray-applied fireproofing
B. Thermal system insulation on pipes
C. Asphalt roofing materials
D. Laboratory fume hood linings
Correct Answer: C
Rationale: Asphalt roofing materials fall under Class II asbestos
because they are non-thermal system building materials such as floor
tiles, roofing, and siding, unlike Class I spray-applied insulation.
2. Class II asbestos work primarily involves removal of:
A. Surfacing materials
B. Thermal system insulation
C. Non-friable manufactured materials
D. Asbestos-containing ceiling plasters
,Correct Answer: C
Rationale: Class II asbestos includes non-friable, manufactured
building materials that are not thermal system insulation, such as
floor tiles and roofing products.
3. Which PPE is most appropriate when handling Class II asbestos
materials?
A. No respiratory protection required
B. Surgical mask only
C. N95 respirator minimum (or higher as required)
D. No protective clothing required
Correct Answer: C
Rationale: A properly fitted respirator such as an N95 or higher
(depending on exposure risk) is required to prevent inhalation of
asbestos fibers.
4. What is the primary hazard associated with disturbing Class II
asbestos materials?
A. Radiation exposure
B. Release of airborne asbestos fibers
C. Chemical burns
D. Explosion risk
Correct Answer: B
,Rationale: Disturbing asbestos-containing materials can release
microscopic fibers into the air, which are hazardous when inhaled.
5. Before starting Class II asbestos removal, workers must first:
A. Begin demolition immediately
B. Conduct a hazard assessment and isolation of work area
C. Remove PPE after entry
D. Use dry sweeping methods
Correct Answer: B
Rationale: A proper hazard assessment and containment of the work
area are required before any asbestos disturbance begins.
6. Which method is preferred for minimizing dust during Class II
asbestos removal?
A. Dry scraping
B. High-pressure air blasting
C. Wet methods
D. Power sanding
Correct Answer: C
Rationale: Wet methods help suppress dust and prevent asbestos
fibers from becoming airborne.
7. What type of containment is typically used for Class II asbestos
work?
, A. No containment required
B. Full negative pressure enclosure always required
C. Limited or glove bag containment depending on material
D. Open-air removal is preferred
Correct Answer: C
Rationale: Class II work may require partial containment or glove bags
depending on the material and disturbance level.
8. Which tool should be avoided when removing asbestos floor tiles?
A. Manual scraper
B. Heat gun
C. Dry power sander
D. Hand tools with water spray
Correct Answer: C
Rationale: Dry power sanding creates airborne asbestos fibers and
must be avoided.
9. What is the purpose of decontamination procedures in asbestos
removal?
A. Increase productivity
B. Prevent spread of asbestos fibers
C. Reduce noise levels
D. Improve lighting
Correct Answer: B
