• Personal Protective Equipment (PPE): Selection and use of respirators and protective
clothing.
Practice MCQ Questions & Rationales
1. According to New Jersey state law (NJAC 12:120), a written "Notification of Intent" to
perform asbestos work must be submitted to the state how many days prior to the start of
the project?
A. 24 hours
B. 5 calendar days
C. 10 calendar days
D. 30 business days
Correct Answer: C. 10 calendar days ✅
Rationale: Under NJAC 8:60-7 and 12:120-7, licensees must notify both the NJ Department of
Health and the NJ Department of Labor at least 10 calendar days before beginning asbestos
work.
2. OSHA's Permissible Exposure Limit (PEL) for asbestos is 0.1 fibers per cubic centimeter
(f/cc) of air as an 8-hour time-weighted average (TWA). What is the specific "Excursion Limit"
for a 30-minute sampling period?
A. 0.5 f/cc
B. 1.0 f/cc
,Page 3 of 92
C. 2.0 f/cc
D. 0.01 f/cc
Correct Answer: B. 1.0 f/cc ✅
Rationale: OSHA 29 CFR 1926.1101 sets the excursion limit at 1.0 f/cc averaged over 30
minutes to protect workers from short-term, high-intensity exposure.
3. Which classification of asbestos work involves the removal of friable thermal system
insulation (TSI) or surfacing material, representing the highest risk?
A. Class I
B. Class II
C. Class III
D. Class IV
Correct Answer: A. Class I ✅
Rationale: Class I work involves the removal of the most hazardous materials, such as sprayed-
on insulation or TSI from boilers and pipes, requiring the strictest controls.
4. To maintain a valid New Jersey Asbestos Supervisor permit, how many hours of annual
refresher training are required?
A. 4 hours
B. 7 hours
C. 8 hours
D. 16 hours
Correct Answer: C. 8 hours ✅
, Page 4 of 92
Rationale: While workers require 7 hours of annual refresher training, asbestos
supervisors must complete at least 8 hours to renew their state-issued permits.
5. What is the mandatory minimum thickness for plastic sheeting used as a "critical barrier"
or dropcloth in a Class I asbestos work area?
A. 2 mil
B. 4 mil
C. 6 mil
D. 10 mil
Correct Answer: C. 6 mil ✅
Rationale: OSHA and NJ standards require 6 mil plastic for critical barriers and dropcloths to
ensure the containment is durable enough to prevent fiber migration.
6. Which term describes materials like thermal system insulation in buildings constructed
before 1980 that must be treated as containing asbestos unless proven otherwise by testing?
A. ACM (Asbestos Containing Material)
B. PACM (Presumed Asbestos Containing Material)
C. RACM (Regulated Asbestos Containing Material)
D. Friable Material
Correct Answer: B. PACM ✅
Rationale: Presumed Asbestos Containing Material (PACM) covers TSI and surfacing materials
in older buildings (pre-1980) that are assumed to be hazardous until lab analysis confirms they
are not.
