Question 1
What is a lead-based paint hazard?
Options:
A) Any paint containing lead in any concentration
B) Any condition that causes exposure to lead from lead-
contaminated dust, soil, deteriorated lead-based paint, or from
lead-based paint present on accessible, friction, or impact
surfaces that would result in adverse human health effects
C) Only paint that is visibly peeling or chipping
D) Paint containing more than 0.5% lead by weight
Correct Answer: B) Any condition that causes exposure to
lead from lead-contaminated dust, soil, deteriorated lead-
based paint, or from lead-based paint present on accessible,
friction, or impact surfaces that would result in adverse
human health effects
,Rationale: The definition of a lead-based paint hazard
encompasses any condition that causes exposure to lead from
multiple sources (dust, soil, deteriorated paint, or paint on
accessible surfaces) that could result in adverse health effects.
This comprehensive definition recognizes that lead hazards exist
beyond just the presence of lead paint.
Question 2
What is the purpose of a risk assessment?
Options:
A) To identify all lead-based paint in a dwelling
B) To determine the presence of lead-based paint hazards and
identify acceptable abatement and interim control strategies
C) To test all surfaces for lead content
D) To enforce lead abatement regulations
Correct Answer: B) To determine the presence of lead-based
paint hazards and identify acceptable abatement and interim
control strategies
Rationale: A risk assessment is an on-site investigation that
includes investigating the age, history, management, and
maintenance of the dwelling; conducting a visual assessment;
, performing limited environmental sampling (dust wipe samples,
soil samples, deteriorated paint samples); and reporting results
that identify acceptable abatement and interim control strategies
based on specific conditions and the owner's capabilities.
Question 3
Which of the following best describes primary prevention of lead
poisoning?
Options:
A) Medical treatment of children with elevated blood lead levels
B) Blood lead screening programs to identify children with
elevated levels
C) Lead-based paint risk assessments and abatement in housing
before children are lead poisoned
D) Emergency medical care for acute lead poisoning
Correct Answer: C) Lead-based paint risk assessments and
abatement in housing before children are lead poisoned
Rationale: Primary prevention focuses on preventing lead
exposure before it occurs by identifying and controlling lead
hazards in housing before children are exposed. This is the most
effective approach to preventing childhood lead poisoning.
