1. What is the primary role of an asbestos supervisor on a project site?
a) Collect air samples
b) Enforce OSHA and EPA regulations on site
c) Perform medical surveillance
d) Approve laboratory analysis
b) Enforce OSHA and EPA regulations on site
Supervisors ensure compliance with all asbestos regulations and oversee safe work
practices.
2. Which federal agency regulates worker exposure to asbestos on construction sites?
a) EPA
b) DOT
c) OSHA
d) NIOSH
c) OSHA
OSHA sets permissible exposure limits and workplace standards for asbestos in
construction.
3. The OSHA permissible exposure limit (PEL) for asbestos is:
a) 0.1 f/cc as an 8-hour TWA
b) 0.5 f/cc as a 15-minute STEL
c) 0.01 f/cc as an 8-hour TWA
d) 1.0 f/cc ceiling limit
a) 0.1 f/cc as an 8-hour TWA
OSHA’s standard is 0.1 fibers per cubic centimeter averaged over 8 hours.
,4. Which type of respirator is generally required for asbestos removal operations?
a) Surgical mask
b) Half-mask air-purifying respirator with HEPA filters
c) N95 disposable mask
d) None if wet methods are used
b) Half-mask air-purifying respirator with HEPA filters
HEPA filtration is required to protect workers from airborne asbestos fibers.
5. Friable asbestos refers to:
a) Any asbestos that is intact and sealed
b) Material that can be crumbled with hand pressure
c) Asbestos in roofing shingles only
d) Asbestos that is non-friable under all conditions
b) Material that can be crumbled with hand pressure
Friable asbestos easily releases fibers, making it more hazardous.
6. Which regulation governs asbestos in schools and public buildings?
a) AHERA
b) TSCA Title II
c) Clean Air Act Section 112
d) OSHA 1910.134
a) AHERA
The Asbestos Hazard Emergency Response Act (AHERA) requires inspections and
management plans in schools.
7. Negative pressure enclosures are required to:
a) Prevent fiber release outside the work area
b) Increase worker airflow comfort
c) Lower humidity levels
d) Reduce cost of cleanup
a) Prevent fiber release outside the work area
Negative pressure systems ensure air flows inward, preventing contamination
outside.
8. A decontamination unit must have at least how many chambers?
a) One
b) Two
c) Three
d) Four
c) Three
Worker decon units typically require an equipment room, shower, and clean room.
, 9. What is the main purpose of wet methods in asbestos removal?
a) Save time on cleanup
b) Reduce airborne fiber release
c) Comply with state licensing rules only
d) Make ACM heavier for disposal
b) Reduce airborne fiber release
Wet methods minimize asbestos fibers from becoming airborne.
10. Which of the following must asbestos supervisors keep on site?
a) OSHA regulations only
b) Copies of worker licenses, medical clearance, and training records
c) Laboratory certifications only
d) EPA disposal permits only
b) Copies of worker licenses, medical clearance, and training records
Supervisors must maintain compliance documentation at the job site.
11. The EPA NESHAP regulation requires notification prior to asbestos abatement of:
a) Only schools
b) Any renovation or demolition with regulated ACM above threshold amounts
c) Only residential homes
d) Only power plants
b) Any renovation or demolition with regulated ACM above threshold amounts
NESHAP requires prior notice to EPA/state before certain ACM projects.
12. Regulated asbestos-containing material (RACM) includes:
a) Friable ACM only
b) Category I non-friable that will be sanded, ground, or abraded
c) Category II non-friable likely to become friable
d) All of the above
d) All of the above
RACM includes friable ACM and non-friable that may be disturbed.
13. Which of the following is an acceptable method of asbestos waste disposal?
a) Burying at any landfill
b) Sealing in leak-tight containers with proper labels and disposing at approved
landfill
c) Burning to ash
d) Mixing with concrete and reusing
b) Sealing in leak-tight containers with proper labels and disposing at approved
landfill
Proper packaging and disposal at approved landfills is mandatory.
