Visible dust
Bare soil
The lead inspector/risk assessor shall visually assess painted surfaces in common areas
accessible to children. The lead inspector/risk assessor shall inspect deterioration on friction and
impact surfaces by operating and examining the friction and/or impact surfaces of several of the
windows and doors that are used most frequently (if known) that contain LBP. The visual
assessment of each unit shall be documented using Form 2 and Form 3 (see Figures B-3 and B-4,
Appendix B). The forms shall be submitted as attachments to the Lead Inspection/Risk
Assessment Report.

Sample Location Selection
******************************************************************************
NOTE: Multi- unit common areas must be sampled when performing multi- unit
assessment sampling. Sampling criteria for community buildings, day care, or other
spaces frequented by children require coordination with customer prior to beginning the
project.
******************************************************************************
The lead inspector/risk assessor shall select single surface dust wipe and soil sample locations
during the visual assessment. Paint chip samples, as required, should be selected in concert with
the lead inspection phase of the project. Sample locations for each unit shall be identified on
each unit floor plan or sketch, and shall be based on visual observations, separate component
systems with distinct histories, pre-assessment unit information (including physical
characteristics, use patterns, previous study results), and on the following:
Lead-based paint surfaces that have been chewed or where chewing or mouthing has
been reported shall be identified as LBP hazards and shall not require sampling.
Chewed surfaces may include interior windowsills, balusters, shelves, stairs, and other
component systems accessible to children's mouths.
Samples shall not be collected from worn portions of the painted surfaces that will be
tested.
Friction or impact surface hazards shall be evaluated by dust wipe analysis, and
accordingly shall not require paint chip sampling.
a. Dust Wipe Sample Locations
One dust sample shall be collected from interior windowsills and floors in all living areas
representing distinct component systems, where one or more children, less than 6 years of age
are most likely to contact dust. Any lead-based paint on a friction surface with visibly
deteriorated paint or that is subject to abrasion shall be sampled where the lead dust levels on the
nearest horizontal surface beneath the friction surface can potentially exceed the dust- lead hazard
action levels in Table A-1.
