work?
A. Hard hat
B. Respirator approved for asbestos
C. Gloves
D. Safety boots
*Correct answer: B. Respirator approved for asbestos — A properly
fitted respirator prevents inhalation of asbestos fibers, which is the
primary route of exposure.
3. How should asbestos-containing materials (ACMs) be handled?
A. Break into small pieces for disposal
B. Wet the material before removal
C. Sweep dry debris
D. Burn it
,*Correct answer: B. Wet the material before removal — Wet methods
reduce airborne asbestos fibers and minimize inhalation risk.
4. What regulation governs asbestos work in the workplace in the
U.S.?
A. OSHA 29 CFR 1910.1001
B. EPA Clean Air Act
C. NFPA 70
D. FDA Food Code

C. Compressed air
D. Water hose
*Correct answer: A. Vacuum with HEPA-filtered vacuum — HEPA
vacuums trap asbestos fibers without releasing them into the air.

D. Emphysema
*Correct answer: B. Mesothelioma — Mesothelioma is a rare cancer
caused almost exclusively by asbestos exposure.
7. During asbestos removal, why is it important to establish a
containment area?
A. To protect workers from heat
B. To prevent asbestos fibers from spreading
, C. To provide a break area
D. To store tools
*Correct answer: B. To prevent asbestos fibers from spreading —
Containment ensures fibers are not released into non-work areas,
protecting workers and the public.
8. What type of respirator is typically required for asbestos work?
A. N95
B. Half-mask with P100 filters
C. Powered Air Purifying Respirator (PAPR)
D. Both B and C
*Correct answer: D. Both B and C — OSHA requires either a P100 filter
respirator or a PAPR for adequate protection against asbestos fibers.
9. How should asbestos waste be labeled for disposal?
A. With a warning sign stating “Asbestos Waste”
B. As regular construction debris
C. No labeling needed if wet
D. Only verbally notify the disposal team
*Correct answer: A. With a warning sign stating “Asbestos Waste” —
Proper labeling ensures that anyone handling the waste is aware of the
hazard.
10. What is the purpose of negative air pressure in an asbestos work
area?
A. To cool the room
B. To contain airborne asbestos fibers
C. To improve ventilation for workers
D. To remove dust from tools
