4. Why Lead Inspection is Important
 Lead dust in very small amounts (approximately the
amount found in a sugar packet) can poison a young
child.
 Older housing used lead-containing paint
 Lead dust can accumulate, especially in windowsills,
window frames, and on floors.
 Rooms where children play or sleep are of particular
concern

5. Lead Inspection
 Visual Inspection
 Lead Test Swabs
 Lead Dust Wipes
 Complete Risk Assessment

9. Lead Inspection or Complete
Risk Assessment
 Process
 Thorough examination of all surfaces
 Both range in cost from $300-600
 If samples taken to testing laboratory, additional costs
 Equipment
 Hand-held X-ray fluorescence paint analyzer (XRF)
analyzes paint chips and dust.
 Should be used by professional

11. Lead Inspection vs. Risk Analysis
 Inspection
 Involves use of X-ray fluorecsence paint analyzer
 Samples may be taken to testing laboratory
 Cost ranges from $300-$450 for 3 bedroom/2 bath house
 Risk Analysis
 Visual inspection of house for paint deterioration and
chips
 Identification of areas of risk
 Cost ranges from $450-$600 for 3 bedroom/2 bath house

30. Swab Testing Discussion
Questions
• If the family had relied on the swab data, how would their
efforts change?
• What are the implications of this differing data?

31. Discussion: Is a Complete
Risk Assessment Necessary?
 Conclusions from both testing procedures
 Why/why not?
