Air and Wipe Sampling
Conduct sampling for lead in accordance with 29 CFR 1926.62 and as
specified herein. Air and wipe sampling shall be directed or performed by
the CP.
a. The CP shall be on the job site directing the air and wipe sampling
and inspecting the PWL or MCL removal work to ensure that the
requirements of the contract have been satisfied during the entire PWL
or MCL operation.
b. Collect personal air samples on employees who are anticipated to
have the greatest risk of exposure as determined by the CP. In
addition, collect air samples on at least twenty-five percent of the
work crew or a minimum of two employees, whichever is greater, during
each work shift.
c. Submit results of air samples, signed by the CP, within 72 hours
after the air samples are taken.
d. Conduct area air sampling daily, on each shift in which lead-based
paint removal operations are performed, in areas immediately adjacent
to the lead control area. Sufficient area monitoring shall be conducted
to ensure unprotected personnel are not exposed at or above 30
micrograms per cubic meter of air. If 30 micrograms per cubic meter of
air is reached or exceeded, stop work, correct the conditions(s)
causing the increased levels. Notify the Contracting Officer
immediately. Determine if condition(s) require any further change in
work methods. Removal work shall resume only after the CP and the
Contracting Officer give approval.
**************************************************************************
NOTE: Include the following paragraph for high
profile, sensitive work such as present in family
housing, child care facilities, administrative
buildings, kitchens, barracks, etc. Use the
following paragraph along with clearance
certification by a third party consultant specified
in paragraph entitled "Clearance Certification" to
determine if significant contamination was due to
the contract work. Surface dust sampling to
determine clearance (i.e., that the work has not
contaminated surfaces within and adjacent to the
control area) should be performed by a third party
to reduce a conflict of interest. Samples must be
conducted by an individual not paid or employed or
otherwise compensated by the lead Contractor. State
or local regulations may require third party.
**************************************************************************
[
e. Before any work begins, [a third party consultant shall] collect and
analyze baseline wipe [and soil] samples in accordance with methods
defined by federal, State, and local standards inside and outside of
the physical boundary to assess the degree of dust contamination in the
facility prior to lead disturbance or removal.]
