US EPA MODEL LEAD INSPECTOR
EXAM QUESTIONS AND ANSWERS
GRADED A+ 2026
Lead Inspector - ANS A certified individual who conducts a surface-by-surface investigation to
determine the presence of lead-based paint.
Lead Risk Assessor Job Description - ANS Determining the existence, nature, severity, and
location of lead-based paint hazards in an entire residential dwelling or child-occupied facility,
and provides a written report explaining the results of the investigation and options for reducing
lead-based paint hazards to the person requesting the lead inspection.
Residential Lead-Based Paint Hazard Reduction Act - ANS (Title X of the Community
Development and Housing Act of 1992) The federal government began to focus on primary
prevention of lead poisoning through identifying and reducing lead hazards.
Importance of lead poisoning prevention/lead-based paint inspections - ANS Focus attention
on the sources of lead that could poison children; and reduce the cost of lead hazard control by
identifying which surfaces are coated with lead-based paint.
Lead inspector job description - ANS Identify the lead-based painted surfaces in housing,
certify the results of an inspection in writing, conduct post-hazard control clearance sampling to
@COPYRIGHT 2026/2027 ALLRIGHTS RESERVED 1
,determine: the specified hazard control strategy was conducted, the area is safe for unprotected
workers to enter, and the area is a safe place for residents and young children to live.
How common is lead pollution? - ANS Lead-based paint is present in roughly 83% of all
hosing stock in the private sector and in roughly 90% of family housing units in the nation's
housing authorities.
Lead-based paint - ANS Paint, varnish, shellac, or other coating on surfaces that contain 1.0
mg/cm^2 or more of lead or 0.5% or more lead by weight.
Lead-based paint hazard - ANS Any condition that causes exposure to lead-contaminated
dust, lead-contaminated-soil, or lead-contaminated paint that is deteriorated or present in
accessible surfaces, friction surfaces, or impact surfaces that would result in adverse human
health effects as identified by the EPA Administrator under TSCA section 403.
Lead-based paint inspection - ANS a surface-by-surface investigation to determine the
presence of lead-based paint. A report is then issued that identifies if there is lead-based paint
present and where it is located.
Deteriorated paint - ANS Any interior or exterior paint that is peeling, chipping, chalking, or
cracking, or is located on an interior or exterior surface of fixture that is damaged or
deteriorated.
Accessible surface - ANS Surface that protrudes from the surrounding area to the extent that
a child can chew the surface and is within three feet or the floor or ground (e.g., window sills,
railing, and the edges of stair treads)
Friction surface - ANS An interior or exterior surfaces that is subject to abrasion or friction
(e.g., certain window, floor, and stair surfaces)
@COPYRIGHT 2026/2027 ALLRIGHTS RESERVED 2
,Impact surface - ANS An interior or exterior surface that is subject to damage from repeated
impacts (e.g., certain parts of door frames)
HUD Guidelines - ANS The primary purpose of the Guidelines is to guide people involved in
identifying and controlling lead-based paint hazards in housing.
What is lead-based paint - ANS 1 milligram per square centimeter (1.0 mg/cm^2) using the
XRF analyzer or 0.5% (or 5,000 parts per million) using laboratory analysis methods
AAS - ANS Atomic absorption spectrometry
A2LA - ANS American Association for Laboratory Accreditation
ASTM - ANS American Society for Testing and Materials
CDC - ANS Center for disease control and prevention
CFR - ANS Code of federal regulations
ICP-AES - ANS Inductively coupled plasma atomic emission spectrometry
NIOSH - ANS National Institute for Occupational Safety and Health (Dept. of Health)
OSHA - ANS Occupational Safety and Health Administration (Dept. of Labor)
Pb - ANS The chemical symbol for lead
@COPYRIGHT 2026/2027 ALLRIGHTS RESERVED 3
, TSP - ANS Trisodium phosphate
RCRA - ANS resource conservation and recovery act
History of Lead Use - ANS Nearly all of the lead in the human environment results from
human activities. Once lead is mined, processed, and introduced into the human environment it
is a potential problem forever. No current technology will destroy it or make it permanently
harmless. However, exposures to lead can be controlled.
The occupational hazards of lead were first reported in 1713 by Bernardo Ramazzini, who
described lead intoxication in potters working with lead glazes.
In 1913, Dr. Alice Hamilton, an American occupations health doctor, wrote about painters and
the hazards of their work.
Why was lead used in paint? - ANS As a pigment, to add durability and corrosion control, and
as a drying agent.
Sources of environmental lead contamination - ANS The principal industrial use of lead is in
the manufacture of electrical storage batteries. Other uses include the production of
ammunition, various chemicals, and sinkers for fishing and etc.
Lead exposure - ANS The major exposure to lead for most adults comes from the work place
(inhalation). Surface dust and soil contamination with lead are the major sources of lead
exposure for infants and young children (ingestion). (Children: drinking water [primarily from
leaded solder, brass fittings and fixtures, and service lines] can contribute to lead poisoning)
