1. What is the primary health concern associated with exposure to
lead-based paint?
a. Hearing loss
b. Neurological and developmental effects
c. Increased bone density
d. Improved respiratory function
Rationale: Lead is a toxic heavy metal that can adversely affect the
nervous system, particularly in children. Exposure can contribute to
developmental, learning, behavioral, and cognitive problems. Adults
may also experience neurological, reproductive, kidney, and
cardiovascular effects.
, 2. Which group is generally considered most vulnerable to the
harmful effects of lead exposure?
a. Healthy adults over age 65
b. Professional painters
c. Young children and developing fetuses
d. People who work outdoors
Rationale: Children, especially those under six years old, are
particularly susceptible because their developing nervous systems are
more sensitive to lead. Lead exposure during pregnancy can also
affect fetal development.
3. In an older building, what should a contractor do before
disturbing painted surfaces when lead-based paint may be
present?
a. Assume the paint is safe
b. Sand the surface to determine its composition
c. Determine whether lead-based paint is present using appropriate
procedures
d. Remove all paint immediately
Rationale: Contractors should not assume that older painted surfaces
are lead-free. Appropriate evaluation, testing, or documentation
,should be used to determine whether lead-based paint is present
before activities that could disturb it.
4. Which work activity is most likely to generate significant lead-
contaminated dust?
a. Installing an undamaged cabinet
b. Dry sanding painted surfaces
c. Measuring a room
d. Applying an approved encapsulant without disturbing the existing
coating
Rationale: Dry sanding can rapidly break painted material into fine
particles that become airborne and settle as contaminated dust. Dust-
generating methods should be controlled through appropriate
containment and work practices.
5. What is the main purpose of containment during lead-paint work?
a. Increase paint drying time
b. Make the work area warmer
c. Prevent contaminated dust and debris from spreading outside the
work area
d. Eliminate the need for personal protective equipment
, Rationale: Containment establishes a controlled work area so lead-
containing dust and debris do not migrate into occupied or otherwise
unprotected areas. Containment complements, rather than replaces,
other required protective measures.
6. Which practice should generally be avoided when performing
lead-paint renovation work?
a. Wet methods
b. HEPA vacuuming
c. Uncontrolled dry sanding
d. Protective containment
Rationale: Uncontrolled dry sanding can create large quantities of
airborne lead dust. Wet methods, appropriate power tools with dust
controls, and HEPA vacuuming are commonly used to reduce dust
generation and migration.
7. What does HEPA stand for?
a. High Energy Paint Application
b. High-Efficiency Particulate Air
c. Hazardous Environmental Protection Assessment
d. High Exposure Prevention Apparatus
