1. What is the primary purpose of lead abatement?
A. To temporarily reduce dust levels
B. To permanently eliminate lead-based paint hazards
C. To repaint buildings
D. To clean surfaces daily
B. To permanently eliminate lead-based paint hazards
Lead abatement is designed to permanently remove or contain lead
hazards, unlike interim controls which are temporary.
2. Which federal agency regulates lead abatement activities?
A. OSHA
B. CDC
C. EPA
D. HUD
C. EPA
The Environmental Protection Agency establishes regulations under
the Toxic Substances Control Act for lead abatement.
3. What is the permissible exposure limit (PEL) for lead under OSHA?
A. 10 µg/m³
B. 25 µg/m³
C. 50 µg/m³
D. 100 µg/m³
C. 50 µg/m³
, OSHA sets the PEL for airborne lead exposure at 50 micrograms per
cubic meter over an 8-hour time-weighted average.
4. Which document outlines procedures for a specific abatement
project?
A. Safety Data Sheet
B. Abatement work plan
C. Inspection checklist
D. Training manual
B. Abatement work plan
The work plan details scope, methods, containment, and safety
procedures for the project.
5. What is the main health risk of lead exposure in children?
A. Kidney stones
B. Neurological damage
C. Lung cancer
D. Diabetes
B. Neurological damage
Lead exposure can impair brain development, causing learning and
behavioral issues in children.
6. Which method is NOT an acceptable lead abatement method?
A. Encapsulation

proper controls.
7. What is the first step before starting abatement work?
A. Painting surfaces
B. Conducting clearance testing
C. Occupant relocation and notification
D. Waste disposal
C. Occupant relocation and notification
Occupants must be informed and relocated to prevent exposure.
, 8. What is the purpose of containment?
A. Improve ventilation
B. Reduce costs
C. Prevent spread of lead dust

C. Prevent spread of lead dust
Containment ensures contaminants do not spread to clean areas.
9. Which PPE is essential during lead abatement?
A. Cotton gloves
B. Respirator

C. Half-mask air-purifying respirator
Properly fitted respirators with HEPA filters are required.
11. What is HEPA filtration?
A. High Energy Particulate Absorber
B. High Efficiency Particulate Air
C. Heat Energy Processing Air
D. Hazard Elimination Particle Action
B. High Efficiency Particulate Air
HEPA filters capture at least 99.97% of particles 0.3 microns in size.
12. What is clearance testing?
A. Initial inspection
B. Worker evaluation
C. Post-abatement verification
D. Waste tracking
C. Post-abatement verification
Clearance testing ensures lead levels are safe after abatement.
