Paint chip samples shall be collected for all inconclusive XRF readings in addition to those
surfaces where the XRF cannot be properly operated (e.g., small, rounded, surfaces etc.). The
location of all paint chip samples shall be documented on the building drawing and documented
in accordance with this SOW.
2.2.1.5
Specific Requirements for Multi-Family Housing
******************************************************************************
NOTE: The following requirements should be selected for multi- family housing. These
requirements are in addition to those listed in Paragraph 2.2.1 through 2.2.1.4.
******************************************************************************
Contractor shall identify testing combinations and conduct XRF testing in common areas and
building exteriors. The lead inspector/risk assessor shall classify XRF results following the
Multi-Family Decision Flow Chart provided Figure B-2 Appendix B. Paint chip samples taken
in accordance with the chart to confirm XRF readings shall be taken and s ubmitted to the
laboratory following the laboratory's SOP for collecting paint chip samples to determine lead
loading per cc of surface area, and ASTM's Standard Practice for Field Collection of Dried
Paint Samples for Lead Determination by Atomic Spectrometry Techniques (E 1729).
2.2.2
Risk Assessment
2.2.2.1
Visual Assessment
****************************************************************************
NOTE: Since lead testing will be performed in conjunction with the risk assessment, the
lead inspector/risk assessor shall immediately review XRF results and determine if the
potential hazard areas contain LBP.
******************************************************************************
The lead inspector/risk assessor shall perform concurrently with the lead inspection visual
assessment, an assessment of all selected units to locate potential LBP hazards and to evaluate
the magnitude of each hazard. Following the floor plans or sketches, the lead inspector/risk
assessor shall visually inspect the unit exterior and every room of each unit that will be assessed
to evaluate paint and building conditions. Every lead-based paint component system with the
same distinct painting history (see Glossary) testing positive for lead shall be inspected for
The lead inspector/risk assessor shall review the XRF data recorded on Form 1 (see Figure B-1,
Appendix B) and identify through observation:
Any friction surface or impact surface with visibly deteriorated paint, and
All other lead-based paint surfaces with visible deteriorated paint.
