The New Jersey Asbestos Supervisor Exam assesses the knowledge and skills required to safely oversee
asbestos abatement projects in compliance with federal, state, and local regulations. This exam evaluates
competency in identifying asbestos-containing materials, implementing proper work practices, utilizing
personal protective equipment, conducting air monitoring, and ensuring regulatory adherence under N.J.A.C.
12:120 and OSHA/EPA standards. The assessment consists of multiple-choice and scenario-based questions
that emphasize real-world application, critical decision-making, and professional responsibility. Candidates
must demonstrate mastery of health risks, containment procedures, decontamination protocols, emergency
response, recordkeeping, and supervisory leadership to protect workers, building occupants, and the
environment during asbestos removal operations.
Section One: Questions 1–100
Question 1
What is the primary physical characteristic of asbestos that makes it hazardous to human health?
,A. Its high thermal conductivity
B. Its ability to burn at high temperatures
C. Its fibrous structure that becomes airborne and inhalable
D. Its chemical reactivity with water
🟢 C. Its fibrous structure that becomes airborne and inhalable
🔴 RATIONALE: Asbestos consists of microscopic fibrous crystals that, when disturbed, become airborne and
can be inhaled. These fibers penetrate deep into the lungs, causing serious diseases like asbestosis, lung cancer,
and mesothelioma.
Question 2
Which New Jersey regulatory code specifically governs asbestos abatement license performance standards?
A. N.J.A.C. 5:23-8
B. N.J.A.C. 12:120
C. N.J.A.C. 7:26
D. N.J.A.C. 8:60
🟢 B. N.J.A.C. 12:120
🔴 RATIONALE: N.J.A.C. 12:120 contains the license performance standards for asbestos work in New Jersey,
including requirements for compliance with EPA, OSHA, and state regulations.
,Question 3
What is the minimum passing clearance air fiber concentration for abatement actions ≤160 square feet when
using PCM analysis?
A. ≤0.02 f/cc
B. ≤0.01 f/cc
C. ≤0.005 f/cc
D. ≤0.05 f/cc
🟢 B. ≤0.01 f/cc
🔴 RATIONALE: According to N.J.A.C. 12:120-4.7, clearance air samples for abatement actions ≤160 square
feet are acceptable when each sample shows fiber concentration ≤0.01 f/cc of air.
Question 4
Which asbestos-related disease has the longest typical latency period?
A. Asbestosis
B. Lung cancer
C. Mesothelioma
D. Gastrointestinal cancer
🟢 C. Mesothelioma
🔴 RATIONALE: Mesothelioma typically has a latency period of 20-50 years after exposure, which is longer
than asbestosis or lung cancer, making it one of the longest-latency asbestos-related diseases.
, Question 5
How many total training hours are required for New Jersey Asbestos Abatement Supervisor initial certification?
A. 28 hours
B. 30 hours
C. 35 hours
D. 40 hours
🟢 C. 35 hours
🔴 RATIONALE: The New Jersey Asbestos Abatement Supervisor Initial Course requires 35 total training
hours, including 14 hours of hands-on training.
Question 6
Which respiratory protection factor is required for supervisor-level asbestos work in high-concentration
environments?
A. APF 10
B. APF 50
C. APF 1000
D. APF 10,000
🟢 D. APF 10,000
🔴 RATIONALE: For high-concentration asbestos environments, a full-facepiece powered air-purifying
respirator (PAPR) or supplied-air respirator with APF 10,000 is required to ensure adequate protection.
