What is the primary objective of a Lead Paint Inspection? - to discover lead paint
TSCA Title IV, Section 402/404 Rule directed EPA to; - develop training and certification requirements for
lead professionals. Individuals performing inspections and risk assessments for lead hazards must be
certified through the EPA accredited program
,T/F EPA's debris rule advises contractors that lead waste generated during renovation and remodeling of
residential housing is now waived from RCRA's rule and can be disposed of as municipal waste - True
T/F OSHA established the standard for the worker's permissible exposure limit, action limit, and
exposure time while abating lead - True
T/F Section 1012/1013 within Title X are sections referring to HUD rules - True
Y/N Are lead inspections mandatory in pre 1978 housing? - No
A lead inspection is a - surface by surface investigation for lead based paint.
Two most common ways for lead to enter the body? - ingestion and inhalation
What body system is most affected by lead poisoning? - the nervous system
The set of measures designed to permanently eliminate lead-based paint hazards for at least 20 years? -
abatement
T/F there is no established time frame for abatement of lead based paint in housing. However, all lead-
based paint hazards must be abated from a target house when the project is funded in the amount of
$25,000 or more through HUD - True
T/F The most recent ruling by the CDC is that a child is suffering a health risk at just 5 ug/dL of lead in the
blood but the risk of death can occur from 80 ug/dL or higher. - True
What abatement methods can be used if lead concentrations in soil are above 5000 ppm where children
are playing? - soil removal, or containing soil under concrete or asphalt
After reducing lead hazards in a property who must perform clearance testing? - certified inspector or
risk assesor
, T/F Clearance test are performed by taking XRF readings in any 4 rooms of the house where the
abatement or renovations took place. - False
T/F In pre 1978 housing, where a child with an elevated blood lead level has been living, visual
assessments alone can be used to determine if lead hazards have to be abated from the property. - False
How does an inspection differ from a risk assessment? - an inspection identifies the presence of lead
paint; an assessment evaluates the hazards from lead.

motion with an approved wipe; place folded wipe in a sampling tube; clean up sampling materials. - True
Why are dust samples taken? - to identify lead paint hazards; to see if the contractor cleaned up properly
after renovation; to identify a dust hazard from lead that may not be paint

T/F No one should operate the XRF analyzer until they have received radiation safety training - True
What does a performance characteristic sheet for an XRF instrument determine? - XRF specified range;
results that are positive, negative, and inconclusive; calibration check tolerances
