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.
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? - Correct 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 - Correct 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. (NAETI Exam: 20% contribution)
Lead in food - Correct Answer ✔✔ Contamination from containers with lead solder, lead
glaze, or other materials with lead, by airborne lead from industrial or automobile
emissions deposited on to crops or water, by uptake into food crops from lead in soil or
pesticides applications, and doing transportation or processing.
A phase-out of lead solder in cans began in the late 1970s.
Food containers: lead oxide is sometimes used to manufacture glazes for protecting
ceramics and etc.
Lead in other sources - Correct Answer ✔✔ Vinyl miniblinds are another potential
source of lead in a residence.
CDC, CPSC, and the public health have identified the following: crayons (imported from
Chile), painted metal playground equipment, pool cue chalk, calcium supplements
(made from bone or oyster shell), some hair dyes (lead acetate)
CPSC - Correct Answer ✔✔ Consumer Product Safety Commission
Health effects of lead exposure - Correct Answer ✔✔ The three systems where the
effects are most dangerous are: the central and peripheral nervous system. the
cardiovascular system (including the blood forming system), and the kidneys.
Exposure to high concentrations of lead can cause: retardation, convulsions, coma, and
death (sometimes)
Acute vs Chronic exposure - Correct Answer ✔✔ acute - exposure for short time at high
levels
chronic - exposure to low or moderate levels over a long period of time
INSPECTION IS A CRITICAL FIRST STEP IN SOLVING THE LEAD PROBLEM IN
HOMES THROUGHOUT THE UNITED STATES. THE PRIMARY SKILL FOR LEAD
INSPECTOR TO DEVELOP IS? - Correct Answer ✔✔ Documentation of information
Lead base paint is found more often in pre world war 2 housing units than those built
since 1940,although all housing constructed prior to ? Is at risk - Correct Answer ✔✔
