Lead Paint Abatement Supervisor Review Exam Questions And
Answers |Fall 2025/2026 Update | 100% Correct Latest
QUESTION 1:
Which federal agency is primarily responsible for regulating lead-based paint hazards under the
Residential Lead-Based Paint Hazard Reduction Act (Title X)?
A. Environmental Protection Agency (EPA)
B. Occupational Safety and Health Administration (OSHA)
C. Department of Housing and Urban Development (HUD)
D. Centers for Disease Control and Prevention (CDC)
CORRECT ANSWER: A
RATIONALE: The EPA is the principal agency enforcing the Residential Lead-Based Paint Hazard
Reduction Act, focusing on public health protections related to lead exposure. HUD and OSHA
have supportive roles, but regulatory authority for abatement practices originates with the EPA.
QUESTION 2:
Which OSHA regulation sets permissible exposure limits (PELs) for lead in construction work?
A. 29 CFR 1910.1200
B. 29 CFR 1926.62
C. 29 CFR 1904.10
D. 29 CFR 1910.1025
CORRECT ANSWER: B
RATIONALE: OSHA’s 29 CFR 1926.62 governs lead exposure in construction work, including
abatement. The 1910.1025 standard addresses general industry, while 1910.1200 covers the
Hazard Communication Standard.
QUESTION 3:
Before beginning abatement, the supervisor must ensure that:
A. Materials are ordered and stored
B. Workers have completed an OSHA 10-hour course
C. The worksite is properly contained and signage posted
D. Medical surveillance has been completed by all local workers
,CORRECT ANSWER: C
RATIONALE: Proper containment and posting of warning signs prevent unauthorized access and
protect both workers and occupants before abatement begins.
QUESTION 4:
What is the EPA’s definition of lead-based paint?
A. Paint containing lead equal to or greater than 0.7 mg/cm²
B. Paint containing lead equal to or greater than 0.5 mg/cm² or 0.05% by weight
C. Paint with any measurable amount of lead
D. Paint manufactured before 1978
CORRECT ANSWER: B
RATIONALE: EPA and HUD define lead-based paint as having lead equal to or greater than 1.0
mg/cm² or 0.5% by weight. Option B best reflects this federal definition.
QUESTION 5:
Which work practice control minimizes airborne lead dust during paint removal?
A. Dry sanding
B. Open burning
C. Wet methods
D. Use of compressed air
CORRECT ANSWER: C
RATIONALE: Wet methods minimize dust generation and dispersal of lead particles, making
them an essential safe work practice. Dry sanding and compressed air increase exposure risk.
QUESTION 6:
Medical surveillance is required for employees exposed to airborne lead levels exceeding:
A. 25 µg/m³ for 8 hours
B. 30 µg/m³ for 8 hours
C. 40 µg/m³ for 8 hours
D. 50 µg/m³ for 8 hours
CORRECT ANSWER: B
, RATIONALE: OSHA mandates medical surveillance for workers exposed to airborne
concentrations at or above the action level of 30 µg/m³ averaged over an 8-hour period.
QUESTION 7:
When must clearance testing be performed following a lead abatement project?
A. Before containment removal
B. Before any repainting occurs
C. After final cleaning and visual inspection
D. After notification to the state authority
CORRECT ANSWER: C
RATIONALE: Clearance testing is required only after the work area has been thoroughly cleaned
and passes a visual inspection to confirm that no dust or debris remains.
QUESTION 8:
Which document must a supervisor maintain for each lead abatement project?
A. EPA chemical registration certificate
B. Waste disposal training checklist
C. Project record including worker training and waste manifests
D. Building occupancy schedule
CORRECT ANSWER: C
RATIONALE: Documentation of worker qualifications, project activities, and waste disposal
manifests are fundamental for compliance verification and recordkeeping.
QUESTION 9:
During abatement, why is HEPA filtration required on vacuuming equipment?
A. To reduce paint adhesion
B. To trap ultrafine particles including lead dust
C. To improve worker comfort
D. To enable dry sweeping
CORRECT ANSWER: B
RATIONALE: HEPA filters capture particles as small as 0.3 microns, effectively preventing
recirculation of lead dust into the workspace atmosphere.
