Risk Assessment Sample and Sample Location Documentation
All XRF testing locations shall be marked on the floor plans/sketches and Form 1 (Figure B-1,
Appendix B) at the time of actual testing during the inspection phase of the combined
inspection/risk assessment. Paint chip sample locations shall be recorded on the floor plans or
sketches and by filling in the identifying information on Form 4 (Figure B-5, Appendix B).
Single surface dust sample locations shall be recorded on the floor plans or sketches and by
filling in the identifying information on Form 5 (Figure B-6, Appendix B).
Each composite soil sample location and identity shall be recorded on Form 6 (Figure B-7,
Appendix B), and on the floor plans or sketches by sub-sample location. The plans or sketches
shall include property boundaries.
The Contracting Officer reserves the right to audit the Risk Assessment Sample and Sample
Location Documentation for any unit, at any time during the course of the project. The Risk
Assessment Sample and Sample Location Documentation shall be included as an attachment to
the Risk Assessment Sampling Plan following completion of the fieldwork and submitted as a
part of the Lead Inspection/Risk Assessment Report.
2.2.3
Single Surface Dust Sampling
Dust samples shall be collected for analysis by single surface wipe sampling. Dust wipe samples
shall always be collected before paint chip samples to avoid cross-contamination. Gloves shall
always be changed before each additional sample is collected. After donning gloves, do not
touch anything other than the wipe and surface to be sampled. If the wipe is dropped, or contact
is made outside the sampling area, discard the wipe and sample another undisturbed area. In
each unit that will be sampled, discard the first wipe from the dispenser before initiating
sampling. Fold the wipes completely before inserting into the collection tube.
The lead inspector/risk assessor shall collect wipe samples in accordance with ASTM's Standard
Practice for Field Collection of Settled Dust Samples Using Wipe Sampling Methods for Lead
Determination by Atomic Spectrometry Techniques (E 1728), using wipe materials meeting the
requirements of Standard Specification for Wipe Sampling Materials for Lead in Surface Dust
(E 1792). (see AIHA web site (http://www.aiha.org) for a listing of wipe vendors meeting
ASTM Method E 1792 criteria.)
