NJ LEAD SUPERVISOR TEST PREP QUESTIONS & ANSWERS SOLVED
ANSWERS/NEWEST UPDATE!!
Question 1
Which New Jersey Administrative Code specifically governs the Lead Hazard Evaluation and
Abatement Code?
A) NJAC 8:51
B) NJAC 8:62
C) NJAC 5:17
D) NJAC 7:26
E) NJAC 5:23
Correct Answer: C) NJAC 5:17
Rationale: NJAC 5:17 is the primary regulation in New Jersey for Lead Hazard Evaluation
and Abatement. It dictates the procedures for inspections, risk assessments, and the
technical requirements for performing abatement work within the state.
Question 2
According to NJAC 5:17, which internal containment level requires one layer of 6-mil poly to be
extended every 5 feet from the work area?
A) Level 1
B) Level 2
C) Level 3
D) Level 4
E) Level 5
Correct Answer: A) Level 1
Rationale: Internal Level 1 containment is the most basic form of protection, requiring a
single layer of polyethylene plastic sheeting to be spread on the floor extending at least 5
feet in all directions from the specific work surface to catch debris.
Question 3
Under NJAC 5:17 Level 2 containment, what is the specific requirement regarding doorway
protection?
A) Doorways must be sealed with duct tape and no plastic
B) Doorways must have two layers of poly with a flap (z-flap)
C) Doorways must be removed from their hinges
D) Doorways must be boarded up with plywood
E) Only a single sheet of poly is required
Correct Answer: B) Doorways must have two layers of poly with a flap
Rationale: Level 2 containment requires a higher degree of isolation. It mandates two layers
of plastic with a flap system on all doorways to the work area to prevent the migration of
lead dust into non-work areas while allowing worker ingress and egress.
Question 4
What is the primary difference between Internal Level 3 and Level 4 containment in NJ lead
, 2
abatement?
A) Level 3 requires residents to leave the building permanently
B) Level 4 allows residents to return at the end of the day before clearance
C) Level 3 allows residents to return at the end of the day after cleanup; Level 4 requires them to
stay out until final clearance is given
D) Level 3 has no time limit
E) Level 4 does not require a HEPA vacuum
Correct Answer: C) Level 3 allows residents to return at the end of the day after cleanup;
Level 4 requires them to stay out until final clearance is given
Rationale: Level 3 containment is used for shorter durations (maximum 5 days) where
residents can re-occupy the dwelling at night after a daily cleanup. Level 4 is for more
intensive projects where the risk is higher, and residents are barred from the unit until a
lead-safe clearance is officially achieved.
Question 5
NJAC 8:51 (Chapter 51) is the regulation specifically designated for:
A) Certification of lead workers
B) Childhood lead poisoning and Elevated Blood Lead levels (EBLs)
C) Hazardous waste disposal
D) Respiratory protection programs
E) Structural engineering codes
Correct Answer: B) Childhood lead poisoning and Elevated Blood Lead levels (EBLs)
Rationale: NJAC 8:51 is administered by the Department of Health. It focuses on the public
health response to children identified with elevated blood lead levels, including case
management and environmental interventions.
Question 6
Which regulation establishes the standards for the certification and training of lead-based paint
professionals in New Jersey?
A) NJAC 5:17
B) NJAC 8:62
C) 29 CFR 1910.134
D) NJAC 7:26
E) NJAC 8:51
Correct Answer: B) NJAC 8:62
Rationale: NJAC 8:62 sets the criteria for training providers and the certification process
for individuals seeking to become lead workers, supervisors, inspectors, or risk assessors in
New Jersey.
Question 7
The OSHA regulation 29 CFR 1910.1200 (Hazard Communication) requires contractors to
, 3
maintain what specific documentation on-site?
A) Personal fit test records
B) Daily air monitoring logs
C) A book of Safety Data Sheets (SDS) for all chemicals and products used
D) The contractor’s insurance policy
E) Copies of the NJAC 5:17 manual
Correct Answer: C) A book of Safety Data Sheets (SDS) for all chemicals and products used
Rationale: The "HazCom" standard ensures that workers are informed about the hazards
of chemicals they work with. This is achieved through proper labeling and the availability
of Safety Data Sheets (SDS), which must be organized and accessible to all employees on
the job site.
Question 8
Which federal agency was specifically created to manage and provide affordable housing and
created the Lead-Based Paint Poisoning Prevention Act (LBPPA)?
A) EPA
B) OSHA
C) HUD
D) FDA
E) NIOSH
Correct Answer: C) HUD
Rationale: HUD (U.S. Department of Housing and Urban Development) focuses on housing-
related issues. They developed the specific guidelines for the evaluation and control of lead-
based paint hazards in federally assisted housing and are a primary source of industry
standards.
Question 9
In New Jersey, what does "UCC" stand for in the context of construction and abatement?
A) Universal Lead Code
B) Uniform Construction Code
C) United Contractors Consortium
D) Underwriters Certification Code
E) Unit Cleanup Criteria
Correct Answer: B) Uniform Construction Code
Rationale: The Uniform Construction Code (UCC) is the set of standards that governs all
construction and building activity in NJ. Lead supervisors must ensure their abatement
methods (like enclosure) comply with these broader building codes.
Question 10
A "GFCI" is a safety device used on abatement sites to prevent:
A) Lead dust inhalation
, 4
B) Fall hazards
C) Electrical shock
D) Hazardous waste spills
E) Fire spreading
Correct Answer: C) Electrical shock
Rationale: A Ground Fault Circuit Interrupter (GFCI) is a shock suppressor. Because lead
abatement often involves the use of water (misting/wet-cleaning) alongside power tools
(HEPA vacuums), GFCIs are required to protect workers from electrical grounding issues
in damp environments.
Question 11
What is a "PFAS" in the context of worker safety?
A) Lead testing equipment
B) Personal Fall Arrest System
C) Plastic Film Adhesive System
D) Permanent Federal Abatement Standard
E) Polyurethane Filter Air Sampler
Correct Answer: B) Personal Fall Arrest System
Rationale: A Personal Fall Arrest System (PFAS) consists of a harness, lanyard, and anchor
point. Lead supervisors must ensure workers use PFAS when working at heights (such as
exterior abatement on scaffolding) to prevent fatal falls.
Question 12
Following the completion of lead hazardous work, what must the contractor provide to the
property owner?
A) A box of lead-free paint
B) A verbal confirmation that the job is done
C) A written disclosure of the work performed along with the scope of work
D) A copy of the supervisor’s blood test results
E) The used HEPA filters
Correct Answer: C) A written disclosure of the work performed along with the scope of
work
Rationale: New Jersey law requires clear communication and record-keeping. Providing a
written disclosure and scope of work ensures the owner has a permanent record of what
hazards were addressed and what methods (abatement vs. interim controls) were used.
Question 13
When using the enclosure method (such as drywall) to manage lead-based paint, screws must
penetrate how deep into the stud or underlying structure?
A) 1/4 inch
B) 1/2 inch
