2025 Q&A | INSTANT DOWNLOAD PDF
1. Which of the following is the primary health risk associated with
asbestos exposure?
A. Skin cancer
B. Liver failure
C. Lung cancer
D. Renal disease
Lung cancer, mesothelioma, and asbestosis are primary diseases caused by
inhaling asbestos fibers.
2. What type of respirator is typically required for workers during Class I
asbestos removal?
,A. Surgical mask
B. Half-face APR
C. Full-face powered air-purifying respirator (PAPR)
D. Dust mask
Class I work involves high-risk materials, requiring high-level respiratory
protection like PAPRs or full-face respirators.
3. The most effective method of asbestos fiber control during abatement
is:
A. Wet methods
B. Ventilation
C. Wet methods combined with local exhaust ventilation
D. Manual sweeping
Combining wetting agents and HEPA-filtered ventilation reduces airborne
fibers effectively.
4. A negative exposure assessment (NEA) is:
A. Proof of no asbestos
B. Not required on abatement jobs
C. A documented demonstration that employee exposures are below PELs
D. An air clearance test
A NEA shows that exposures are under the permissible exposure limit
(PEL), often needed for compliance.
5. Class I asbestos work includes:
,A. Roofing repair
B. Removal of thermal system insulation (TSI)
C. Demolition of drywall
D. Flooring tile removal
Class I includes removal of TSI or surfacing materials, the most hazardous
category.
6. Which of the following must be HEPA-filtered on an abatement site?
A. Personal air monitors
B. Vacuum cleaners
C. Water filtration systems
D. Pressure gauges
Only HEPA-filtered vacuums are approved for asbestos cleanup due to their
fiber retention capacity.
7. The regulated area during an abatement project is:
A. Anywhere with no work activity
B. Limited to worker break rooms
C. The space where airborne fiber levels may exceed PELs
D. The administrative office
The regulated area is restricted to essential personnel due to fiber hazards.
8. The first step before beginning asbestos abatement is:
, A. Scheduling an inspection
B. Preparing a written abatement plan
C. Air sampling
D. Notifying neighbors
A detailed work plan ensures safety, compliance, and clarity for regulatory
oversight.
9. Wet methods reduce asbestos exposure by:
A. Dissolving asbestos
B. Covering the asbestos
C. Minimizing airborne fiber release
D. Strengthening ACM
Water binds to asbestos fibers, making them heavier and less likely to
become airborne.
10. A glovebag is typically used for:
A. Floor tile removal
B. Pipe insulation removal
C. Popcorn ceiling scraping
D. Roofing jobs
Glovebags isolate pipe sections and allow safe removal without
contaminating the entire room.
11. The OSHA permissible exposure limit (PEL) for asbestos is:
