Underground Construction - July 2021 - 39
EDITION 65 | JULY 2021 | NASSCO.ORG
NASSCO has been providing industry
leadership with the development
and adoption of recommended
industry practices for the handling of
styrenated resins for CIPP.
In 2009, NASSCO published the
inaugural " Guidelines for the Safe
Use and Handling of Styrene-Based
Resins in CIPP. " This guideline was
updated in later versions, culminating
in the 2020 standard that incorporated
findings from Trenchless Technology
Center's (TTC) " CIPP Emissions
Phase 2: Evaluation of Air Emissions
from Polyester Resin CIPP with
Steam Cure, " For worker safety, the
guidelines include the following:
* Establish a work zone perimeter
of a 15-foot cleared radius around
emission stacks, with stack
discharges being a minimum of
six (6) feet above ground surface.
Workers should avoid entering the
cleared perimeter for prolonged
exposures.
* Equip workers with appropriate
protections when entering the
cleared perimeter and other areas
with possible styrene exposure.
* Consider localized job site air
monitoring to confirm that safety
measures are working as intended,
with provisions for additional
protective measures as needed.
NASSCO is adopting these recommendations and
research findings into its standards and the next version
of the Inspector Training and Certification Program
(ITCP™), which is currently under revision and should
be available by 2022. Meanwhile, the TTC is continuing
its research with Phase 3 investigations that should will
also be available in 2022. Finally, NASSCO's Technical
Advisory Council would like your feedback about
the adoption and revisions to the published styrene
recommendations noted in the latest guidelines for
CIPP. Please email your feedback to tac@nassco.org.

findings and recommendations, please visit nassco.org.
