  • What is Lead Based Paint (LBP)?
  • Health Effects Targeting Children Under the Age
    of 6
  • Key Federal Regulations
  • Assessments for LBP and Other Residential Lead
    Hazards
  • Quality Control on Lead Inspections
  • Lead Hazard Control and Abatement

TOPIC 1
WHAT IS LEAD BASED PAINT?
3
Lead What is It?
  • Chemical Symbol - Pb
  • Heavy Gray Metal
  • Soft and Pliable
  • Galena most common lead-containing ore

4
What Products Contain or Contained Lead?
  • Paints and Varnishes
  • Pottery
  • Gasoline
  • Drinking Water System
  • Solder
  • Flux
  • Brass Fixtures
  • Hobbies
  • Sinkers
  • Ammunition
  • Stain Glass
  • Food Containers
  • Storage Batteries

5
What Makes Paint Lead Based?
  • Lead-Based Paint (LBP)
  • -1.0 mg/cm2 lead on surface
  • -0.5 (5,000 ppm) lead by dry weight
  • CPSC banned the use of Lead-Based Paint in 1978
    standard set
  • at 0.06.
  • Paint today may still contain 0.009 lead in
    liquid paint

6
40 CFR Part 745.65Lead-Based Paint Hazard
  • Dust Lead-Hazard
  • On residential property or child-occupied
    facility
  • Floor
  • 40 ug/square foot
  • Window Sill
  • 250 ug/square foot

7
40 CFR Part 745.65Lead-Based Paint Hazard
  • Soil-Lead Hazard
  • Bare soil on residential property or
    child-occupied property
  • Play Area
  • 400 ppm
  • Rest of yard
  • 1,200 ppm

8
Childs Exposure to Lead
  • Dust and soil are the major routes of exposure
  • Renovations that break surfaces painted with LBP
  • Enters soil through deterioration
  • Young children ingest through normal hand-mouth
    activity (PICA)

9
Lead in Soil
  • Both a direct and indirect source
  • children playing in bare soil
  • tracked or blown into a dwelling
  • Dwellings with exterior lead-based paint
  • more likely to have elevated soil lead levels

10
Lead in Water
  • In 1986 the federal government in the Lead Safe
    Drinking Water Act set the following standards
  • 15 ppb for lead in
  • drinking water from water
  • distribution systems
  • lt0.2 for lead in
  • solder or flux
  • lt8 in other plumbing
  • fixtures today this has
  • been reduced to 0.25

11
Lead in Water
  • Main causes
  • corrosion of lead-containing materials in
    plumbing
  • poorly soldered joints
  • brass fittings
  • private wells
  • plumbing equipment

12
Lead in Water
  • Amount of lead in drinking water depends on the
  • amount and age of lead-containing materials
  • amount of time the water is in contact
  • Corrosiveness of the water
  • hot
  • acidic
  • soft

13
TOPIC 2
HEALTH EFFECTS
14
Body Systems Affected
  • Almost all systems
  • within in the body may be affected by lead
    exposure!

15
Body Systems Most Affected
Central nervous system (CNS)
Cardiovascular system (heart)
Kidneys (renal)
Hematopoietic (Blood forming) system
16
Children
  • More susceptible to effects of lead
  • High levels of lead in the blood may cause
  • permanent CNS damage
  • Low levels of lead in the blood may cause
  • delayed development
  • behavioral problems
  • May not exhibit any obvioussymptoms!

17
Children most at risk for lead poisoning
  • Poor
  • Mexican American
  • Non-Hispanic Black
  • Living in large metropolitan areas
  • Living in older housing

18
Where is lead stored in the body? For how long?
  • Blood
  • ? 5-10, half-life 1 month
  • Kidney
  • ? 5-10, half-life 1 month
  • Bone
  • ? 80-90, half-life 25 years

19
Biological Evaluation
  • The blood lead level is the best initial
    measurement for evaluating lead exposure.
  • The blood lead level
  • indicates the amount of lead circulating in the
    blood stream
  • may be a measure of recent exposure

20
Level of Concern in Children
  • CDC
  • 1970 ? 60 ?g/dL
  • 1971 ? 40 ?g/dL
  • 1975 ? 30 ?g/dL
  • 1985 ? 25 ?g/dL
  • 1991 ? 10 ?g/dL
  • 2012 ? 5 ?g/dL
  • (now called Reference Value)

  • Prepared by Neal B. Freuden
  • January, 2009

46
Definition of Lead Hazard
  • Deteriorated LBP.

  • House Dust, Bare Soil or Drinking Water above
    standards.

47
What is an Inspection?
  • It must be comprehensive and follow the testing
    protocols described in the current regulations.
  • Any Testing that is not comprehensive will be
    called Limited Testing.
  • If lead hazards found and children under 6
    present, inspector does not have to notify state
    and local health departments.

    sent to owner, for All Testing where child is
    present. Owner must give to residents residents
    must acknowledge receipt.

49
Record Keeping
  • All Testing reports shall be retained by owner
    and transferred when passing title until property
    is certified by a licensed lead inspector as
    free of toxic levels of lead.

58
TOPIC 4
ASSESSMENTS FOR LBP AND OTHER RESIDENTIAL LEAD
HAZARDS
59
EPA/HUD - Lead-Based Paint Inspection
  • Examination of painted or finished surfaces for
    lead-based paint
  • Interior and exterior
  • Comprehensive
  • Includes intact paint and areas not to be
    disturbed
  • Performed by a certified LBP inspector
  • 40 CFR 745.227(b)

60
Types of Housing
  • Single-family
  • Any housing with fewer units than a multifamily
    development
  • Results cannot be applied to other dwellings

61
Types of Housing
  • Multifamily
  • Include dwellings with
  • 21 or more units if built before 1960 or
  • 10 or more units if built from 1960 through 1978
  • Use of random sampling

62
XRF Devices
63
The Performance Characteristics Sheets for the
XRFs
  • The Performance Characteristics Sheet (PCS) for
    each XRF instrument provides important details
    for the following
  • Step 1 Calibration Checks
  • Step 2 Testing
  • Step 3 Substrate Corrections
  • Step 4 Classifying Results

64
Inspections in Multifamily Housing
  • Multifamily have the following differences vs.
    single-family inspections
  • not every unit, common area or exterior is
    inspected
  • representatives of these spaces need to be
    selected in a random manner to test
  • classification of XRF results by component is
    required to determine development-wide patterns

65
Compute Sample Size
  • Number of units, common areas, and exterior sites
    to be tested is based upon
  • total number of units
  • similar common areas, or exterior sites in the
    building(s) or on the property, and
  • the date of the construction.
  • Refer to Table 7-3.

66
NUMBER OF UNITS TO INSPECT
67
Compile the results by component type
  • Record measurement for each testing combination
    and classify as
  • Positive
  • Negative
  • Inconclusive

68
Compile the results by component type
  • Example
  • Component Pos Neg Inc
  • Int win sashes 20 75 5
  • Int win trim 12 83 5
  • Int doors 0 95 5
  • Int door trim 2 97 1

69
Decision Analysis
  • Result for component type is
  • Positive if 15 or more of the components are
    positive
  • Negative if
  • 100 of tested component types are negative (OR)
  • 100 of the tested component types are either
    negative or inconclusive AND all the inconclusive
    samples have XRF readings lt1.0 mg/cm2
  • Perform confirmatory testing as required low
    incidence inconclusives and positives

    unit selection methods
  • Environmental sampling of deteriorated paint,
    dust and soil

80
HUD Changes to EPA Risk Assessment
BASIC SAMPLING SCHEME-Single Surface wipes
encouraged. Composites are discouraged for a
variety of reasons including a lack of NLLAP
proficiency program.
81
HUD Changes to EPA Risk Assessment
BASIC SAMPLING SCHEME-Dwelling Unit-Interior
minimum 2 single surface wipes (floor sill) in
4 rooms entryways In addition Optional
Counter tops, drawers and shelving subject to
friction (kitchens and pantries, for ex.)
collect a dust wipe directly on components and
compare to floor standard (40 ug/ft2)
82
HUD Changes to EPA Risk Assessment
COMMON AREAS Samples only collected on floors
and sills adjacent to dwelling units in which
conducting risk assessment plus a sample in
building entryway
83
HUD Changes to EPA Risk Assessment
OTHER CHANGES Categories of Paint Now only
Intact and Deteriorated and deteriorated have to
be assessed for lead safe work practices for HUD
de minimis and EPA minor maintenance and repair
categories.
84
HUD Changes to EPA Risk Assessment
OTHER CHANGES Intact paint subject to friction
must be tested or assumed to be LBP. It is hazard
if dust underneath on horizontal surface is a
hazard If choose not to collect a dust sample,
must assume intact friction surface with
confirmed or assumed LBP is a hazard
85
HUD Changes to EPA Risk Assessment
Dust Wipe QUALITY CONTROL Blind Field Spikes
not required Blanks 1 per property. If doing
multi-family testing, 1 per 20.
86
HUD Changes to EPA Risk Assessment
SAMPLING FOR SOIL HAZARDS -Sample bare soil in
play areas -Bare soil at the driplines at main
house, detached garages, sheds, etc. (0-3 ft.
from foundation) -Bare soil in other areas of
yard if cumulatively gt 9 SF -Sample depth 5/8
inch -Bare soil in vegetable gardens-sample
depth 3-4 inches
87
Reevaluation
  • If LBP remains after hazard reduction
  • Identify
  • Deteriorated paint surfaces
  • Deteriorated or failed Interim Controls
  • Dust-lead hazards
  • Newly bare soil with soil-lead over standards
  • Performed by certified risk assessor
  • Reevaluation every two years
  • Begins two years after hazard reduction
  • Opportunity to achieve exemption
  • Response to identified hazards

88
Lead in Water
  • Drinking water contributes about 20 to total
    lead exposure for an average 2 year old
  • Ranges from 5 to greater than 50
  • Infants may receive 85 of their total lead
    exposure from drinking water
  • Two types of water
  • Soft
  • More corrosive towards lead (Hot, acidic)
  • Hard
  • Least Corrosive

89
Sampling Methods
  • Water not to be used for at least 6 hours before
    sampling
  • Collect one liter sample (1st Draw)
  • Collected in plastic (Nalgene) bottles
  • Samples should be analyzed within 28 hours
  • Standards EPA Water Distribution Systems
    15 ppb
  • Standards HUD Individual Faucets in a dwelling
    unit 20 ppb

90
TOPIC 5
QUALITY CONTROL
91
Quality Assurance and Control Measures
  • HUD Guidelines recommend the housing owner or
    client evaluate the quality of the LBP inspection
    in one of the following ways
  • Direct observation
  • On-site results
  • Repeated testing
  • Time-and-motion analysis

92
