1. What is the primary health risk associated with lead exposure in
children?
Neurological damage
Lead disrupts brain development in children, causing cognitive and
behavioral impairments.
2. Which federal law primarily regulates lead-based paint hazards in
housing?
Residential Lead-Based Paint Hazard Reduction Act (Title X)
Title X mandates lead disclosure in housing and sets standards for
lead hazard reduction.
3. At what year of construction is housing presumed to contain lead-
based paint unless proven otherwise?
, 1978 or earlier
The U.S. banned lead-based paint for residential use in 1978.
4. What is the most common pathway for lead exposure in children?
Ingestion of lead dust
Children often ingest lead dust through hand-to-mouth activity from
contaminated surfaces.
5. Who enforces lead-safe work practices in renovation projects?
EPA
The Environmental Protection Agency enforces Renovation, Repair,
and Painting (RRP) Rule compliance.
6. What is the OSHA permissible exposure limit (PEL) for airborne lead
for workers?
50 micrograms per cubic meter of air (50 µg/m³)
This limit is averaged over an 8-hour workday to protect workers.
7. What is the main purpose of a lead inspection?
To determine the presence of lead-based paint
An inspection identifies lead-based paint but does not assess the
extent of hazard.
8. What instrument is most often used for on-site lead paint testing?
X-ray fluorescence (XRF) analyzer
XRF devices can detect lead content quickly without damaging
painted surfaces.
,9. What is the threshold lead concentration for paint to be considered
lead-based by EPA standards?
1.0 milligrams per square centimeter (mg/cm²)
This is the regulatory definition in housing and child-occupied
facilities.
10. Which sample type is collected to check for lead in household
dust?
Wipe sample
A wipe sample collects settled dust from surfaces to measure lead
loading.
11. What is the primary purpose of the HUD Guidelines?
To provide procedures for lead hazard evaluation and control
HUD Guidelines outline safe methods for inspecting, assessing, and
controlling lead hazards.
12. Which agency sets drinking water lead limits?
EPA
EPA enforces the Lead and Copper Rule under the Safe Drinking
Water Act.
13. What is the action level for lead in drinking water under the Lead
and Copper Rule?
15 parts per billion (ppb)
This is the concentration at which water systems must take
corrective actions.
, 14. What is the primary advantage of XRF over paint chip sampling?
Immediate results on site
XRF devices provide instant readings without laboratory analysis
delays.
15. How should deteriorated paint be handled in a lead inspection?
Document its location and condition
Inspectors record deteriorated paint because it poses higher risk for
lead dust release.
16. Which blood lead level requires public health intervention for a
child, according to CDC?
3.5 micrograms per deciliter (µg/dL)
CDC lowered the reference value to 3.5 µg/dL to identify children
with elevated exposure.
17. How should XRF readings be recorded?
As measured with calibration data included
Accurate reporting includes raw readings and verification of device
calibration.
18. What is the purpose of a lead risk assessment?
To identify lead hazards and recommend control measures
Unlike an inspection, it evaluates hazard presence and suggests
actions.
