US EPA Model Lead Inspector with 100%correct answers verified for accuracy
Lead Inspector - answer A certified individual who conducts a surface-by-surface investigation to
determine the presence of lead-based paint.
Lead Risk Assessor Job Description - 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 - 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 - 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 - 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? - 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 - 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 - 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 - 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 - 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 - 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 - answer An interior or exterior surfaces that is subject to abrasion or friction
(e.g., certain window, floor, and stair surfaces)
Impact surface - answer An interior or exterior surface that is subject to damage from repeated
impacts (e.g., certain parts of door frames)
HUD Guidelines - 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 - 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 - answer Atomic absorption spectrometry
,A2LA - answer American Association for Laboratory Accreditation
ASTM - answer American Society for Testing and Materials
CDC - answer Center for disease control and prevention
CFR - answer Code of federal regulations
ICP-AES - answer Inductively coupled plasma atomic emission spectrometry
NIOSH - answer National Institute for Occupational Safety and Health (Dept. of Health)
OSHA - answer Occupational Safety and Health Administration (Dept. of Labor)
Pb - answer The chemical symbol for lead
TSP - answer Trisodium phosphate
RCRA - answer resource conservation and recovery act
History of Lead Use - 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? - answer As a pigment, to add durability and corrosion control, and
as a drying agent.
Sources of environmental lead contamination - 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 - 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 - 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.
Children ingest lead-based paint by normal hand-to-mouth activity. Young children absorb a
significantly higher percentage of ingested lead than adults. Lead absorption is increased by
malnutrition and poor diet.
Lead in surface dust and soil can come from? - answer Weathering and chipping of lead-based
paint, scraping and sanding of lead-based paint in preparation for refinishing, renovations that
break surfaces painted with lead-based paint, abrasion and/or impact on doors and windows,
atmospheric fallout from the combustion of leaded gasoline that was deposited prior to the
phase-down in use, factory emissions, dust and dirt that is carried into the home on shoes and
clothing (especially from factories or construction sites or by pets)
Lead in water - answer Lead-contaminated drinking water also contributes to the overall level of
exposure - from as little as 5 percent to more than 50 percent of a child's total lead exposure.
