wri en report explaining the results of the inves ga on and op ons for reducing lead-based paint
hazards to the person reques ng the lead inspec on.
Residen al Lead-Based Paint Hazard Reduc on Act - answer(Title X of the Community Development and
Housing Act of 1992) The federal government began to focus on primary preven on of lead poisoning
through iden fying and reducing lead hazards.
Importance of lead poisoning preven on/lead-based paint inspec ons - answerFocus a en on on the
sources of lead that could poison children; and reduce the cost of lead hazard control by iden fying
which surfaces are coated with lead-based paint.
Lead inspector job descrip on - answerIden fy the lead-based painted surfaces in housing, cer fy the
results of an inspec on in wri ng, 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 pollu on? - answerLead-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 na on's housing authori es.
Lead-based paint - answerPaint, varnish, shellac, or other coa ng 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 - answerAny condi on that causes exposure to lead-contaminated dust, lead-
contaminated-soil, or lead-contaminated paint that is deteriorated or present in accessible surfaces,
fric on surfaces, or impact surfaces that would result in adverse human health effects as iden fied by
the EPA Administrator under TSCA sec on 403.
Lead-based paint inspec on - answera surface-by-surface inves ga on to determine the presence of
lead-based paint. A report is then issued that iden fies if there is lead-based paint present and where it
is located.
Deteriorated paint - answerAny 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 - answerSurface 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)
Fric on surface - answerAn interior or exterior surfaces that is subject to abrasion or fric on (e.g.,
certain window, floor, and stair surfaces)
Impact surface - answerAn interior or exterior surface that is subject to damage from repeated impacts
(e.g., certain parts of door frames)
HUD Guidelines - answerThe primary purpose of the Guidelines is to guide people involved in iden fying
and controlling lead-based paint hazards in housing.
What is lead-based paint - answer1 milligram per square cen meter (1.0 mg/cm^2) using the XRF
analyzer or 0.5% (or 5,000 parts per million) using laboratory analysis methods
AAS - answerAtomic absorp on spectrometry
,A2LA - answerAmerican Associa on for Laboratory Accredita on
ASTM - answerAmerican Society for Tes ng and Materials
CDC - answerCenter for disease control and preven on
CFR - answerCode of federal regula ons
ICP-AES - answerInduc vely coupled plasma atomic emission spectrometry
NIOSH - answerNa onal Ins tute for Occupa onal Safety and Health (Dept. of Health)
OSHA - answerOccupa onal Safety and Health Administra on (Dept. of Labor)
Pb - answerThe chemical symbol for lead
TSP - answerTrisodium phosphate
RCRA - answerresource conserva on and recovery act
History of Lead Use - answerNearly all of the lead in the human environment results from human
ac vi es. Once lead is mined, processed, and introduced into the human environment it is a poten al
problem forever. No current technology will destroy it or make it permanently harmless. However,
exposures to lead can be controlled.
The occupa onal hazards of lead were first reported in 1713 by Bernardo Ramazzini, who described lead
intoxica on in po ers working with lead glazes.
, In 1913, Dr. Alice Hamilton, an American occupa ons health doctor, wrote about painters and the
hazards of their work.
Why was lead used in paint? - answerAs a pigment, to add durability and corrosion control, and as a
drying agent.
Sources of environmental lead contamina on - answerThe principal industrial use of lead is in the
manufacture of electrical storage ba eries. Other uses include the produc on of ammuni on, various
chemicals, and sinkers for fishing and etc.
Lead exposure - answerThe major exposure to lead for most adults comes from the work place
(inhala on). Surface dust and soil contamina on with lead are the major sources of lead exposure for
infants and young children (inges on). (Children: drinking water [primarily from leaded solder, brass
fi ngs and fixtures, and service lines] can contribute to lead poisoning)
Lead paint - answerThe 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 ac vity. Young children absorb a significantly
higher percentage of ingested lead than adults. Lead absorp on is increased by malnutri on and poor
diet.
Lead in surface dust and soil can come from? - answerWeathering and chipping of lead-based paint,
scraping and sanding of lead-based paint in prepara on for refinishing, renova ons that break surfaces
painted with lead-based paint, abrasion and/or impact on doors and windows, atmospheric fallout from
the combus on 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
construc on sites or by pets)
