EXECUTION
[3.1
REMOVAL OF COATINGS CONTAINING HAZARDOUS MATERIALS
**************************************************************************
NOTE: Include NFGS 13283 in any project
specification that requires removal or disturbance
of coating containing hazardous materials. Include
a contractor qualification requirement similar to
the article entitled "Qualifications of Coating
Contractors" in Part 1 of this Section, except that
the contractor shall be qualified to SSPC QP-2. The
removal of coatings containing hazardous materials
and application of new coating system can be
accomplished in a continuous operation if the
contractor provides appropriate coordination of
removal, cleaning, and coating application. It is
specified as two separate operations to allow
separate contractors to accomplish different phases
of project. With the use of SSPC QP-1 and QP-2
requirements in contracts, the same contractor will
generally be accomplishing both phases of work, and
will probably want to perform both phases as a
single operation so as not to have to prepare
surface twice. To accomplish the coating removal
and recoating in a continuous operation, the
contractors plan must be scrutinized for appropriate
controls on the removal process, and on the surface
preparation/coating application process. Delete
this paragraph if no paint containing hazardous
material is to be removed.
**************************************************************************
Coatings containing hazardous materials and identified for disturbance
during surface preparation, including removal, shall be handled in
accordance with Section 13283N REMOVAL AND DISPOSAL OF LEAD CONTAINING
PAINT.

COATING AND ABRASIVE SAMPLE COLLECTION AND TESTING
3.2.1
Coating Sample Collection
Notify Contracting Officer three days in advance of sampling. The
Contracting Officer and either the QC Manager or NACE Coating Inspector
shall witness all sampling. Provide a sample collection kit as required in
Article entitled "Coating Sample Collection and Shipping Kit." Obtain a one
liter quart sample of each batch of each base material, and proportional
samples of each activator based on mix ratio, by random selection from
SECTION 09971
