US EPA Model Lead Inspector (Epa lead) questions and answers
2025\2026 A+ Grade
Lead Inspector
- correct answer A certified individual who conducts a surface-by-surface investigation to determine the
presence of lead-based paint.
Lead Risk Assessor Job Description
- correct answer 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
- correct answer (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
- correct answer 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
- correct answer Identify the lead-based painted surfaces in housing, certify the results of an inspection
in writing, conduct post-hazard control clearance sampling to 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?
- correct answer 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
- correct answer 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
- correct answer 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
- correct answer 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
- correct answer 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
- correct answer 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
- correct answer An interior or exterior surfaces that is subject to abrasion or friction (e.g., certain
window, floor, and stair surfaces)
Impact surface
- correct answer An interior or exterior surface that is subject to damage from repeated impacts (e.g.,
certain parts of door frames)
HUD Guidelines
- correct answer 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
- correct answer 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
- correct answer Atomic absorption spectrometry
A2LA
- correct answer American Association for Laboratory Accreditation
ASTM
- correct answer American Society for Testing and Materials
CDC
- correct answer Center for disease control and prevention
CFR
- correct answer Code of federal regulations
ICP-AES
- correct answer Inductively coupled plasma atomic emission spectrometry
NIOSH
- correct answer National Institute for Occupational Safety and Health (Dept. of Health)
OSHA
- correct answer Occupational Safety and Health Administration (Dept. of Labor)
Pb
- correct answer The chemical symbol for lead
TSP
- correct answer Trisodium phosphate
, RCRA
- correct answer resource conservation and recovery act
History of Lead Use
- correct answer 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?
- correct answer As a pigment, to add durability and corrosion control, and as a drying agent.
Sources of environmental lead contamination
- correct answer 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
- correct answer 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)
Lead paint
- correct answer The amount of lead-based paint in housing is significant - approximately 64 million (pre-
1978) private U.S. residences contain at least some lead-based paint.
