SECTION 1 — Lead Fundamentals & Health
1. What is the primary concern associated with deteriorated lead-based paint?
A. Increased humidity
B. Lead exposure
C. Mold growth
D. Carbon monoxide
Answer: B. Lead exposure
Rationale: Deteriorating lead-based paint can generate chips and dust that create
exposure hazards, particularly for young children.
,2. Lead is most concerning to children because it can affect the:
A. Skeletal system only
B. Nervous system and development
C. Hair follicles
D. Digestive enzymes only
Answer: B. Nervous system and development
Rationale: Lead exposure can adversely affect neurological development,
learning, behavior, and other body systems.
3. Which population is especially vulnerable to lead exposure?
A. Young children
B. Healthy adults only
C. People over age 90 only
D. Athletes only
Answer: A. Young children
Rationale: Developing nervous systems make young children particularly
susceptible to lead's effects.
4. A common route of childhood lead exposure is:
A. Ingestion of contaminated dust
B. Exposure to clean water
C. Breathing oxygen
D. Sunlight
Answer: A. Ingestion of contaminated dust
Rationale: Children frequently ingest lead-contaminated dust through normal
hand-to-mouth activity.
5. Which behavior can increase a child's exposure to lead dust?
,A. Frequent hand washing
B. Hand-to-mouth activity
C. Wearing clean clothing
D. Drinking uncontaminated water
Answer: B. Hand-to-mouth activity
Rationale: Contaminated dust on hands can be transferred to the mouth and
swallowed.
6. Lead-based paint becomes particularly hazardous when it is:
A. Intact and properly maintained
B. Deteriorated or disturbed
C. Covered by intact flooring
D. Stored in a sealed container
Answer: B. Deteriorated or disturbed
Rationale: Deterioration and disturbance can release lead-containing chips and
dust.
7. Friction surfaces are important during a risk assessment because:
A. They never generate dust
B. Paint can be abraded during operation
C. They cannot contain lead
D. They are always exterior surfaces
Answer: B. Paint can be abraded during operation
Rationale: Repeated friction can wear painted surfaces and generate lead-
contaminated dust.
8. Which is an example of a friction surface?
, A. A stationary ceiling
B. A painted window sash rubbing against another component
C. An untouched wall
D. A roof shingle
Answer: B. A painted window sash rubbing against another component
Rationale: Moving components that rub together can create friction-generated
dust.
9. Which is an example of an impact surface?
A. A wall receiving repeated door-handle impacts
B. A ceiling
C. A sealed pipe
D. An undisturbed attic beam
Answer: A. A wall receiving repeated door-handle impacts
Rationale: Repeated impacts can damage painted surfaces and release chips or
dust.
10. Lead can enter the body through:
A. Ingestion
B. Inhalation
C. Both A and B
D. Neither
Answer: C. Both A and B
Rationale: Lead may be swallowed or inhaled depending on the exposure
pathway.
11. Why is lead-contaminated household dust important?
