The assessor shall select single surface dust wipe, paint chip, and soil sample locations during the visual
assessment. Sample locations for each unit shall be identified on each unit floor plan/sketch, and shall
be selected based on visual observations, separate component systems with distinct painting histories,
pre-assessment unit information (including physical characteristics, use patterns, previous study results),
and on the following: Surfaces to be tested for lead include each friction surface or impact surface with
visibly deteriorated paint, and all other surfaces with visibly deteriorated paint. Surfaces that have been
chewed (or where chewing and/or mouthing have been reported) shall be identified as lead-based paint
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 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, age 6 and under 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.
For multi-family dwellings:
In addition to samples required above, interior windowsill and floor dust samples shall be sampled for
lead concentration in:
Common areas adjacent to the sampled residential dwelling or child-occupied facility
Other common areas in the building where the risk assessor determines children six or under might
contact dust according to the following:
Common Areas Multi-Unit Low Rise (up to and including four stories):
One from the entry floor, and
One from the floor of the first story landing of a common hallway, or stairway
If a hallway window is frequently used, the risk assessor shall collect an interior
windowsill sample as a substitute for the first story floor-landing sample.
Common Areas Multi-Unit High Rise (greater than four stories):
Two additional samples from the corridor of every fourth floor
One sample from the floor areas
One sample from the windowsill.
Two additional samples from stairways: one from the stair treads, one from the landing
For child-occupied facilities:
