Safety

Keeping our workers safe, our communities healthy and our natural resources protected is of utmost importance to NASSCO and we express this in everything we do. NASSCO’s Health and Safety Committee provides support to all other NASSCO Committees to ensure safety is always front and center.  Dedicated members of our Pipe Rehab Committee’s CIPP Safety Workgroup continue to investigate the safety of emissions in the Cured-in-Place Pipe process with independent research from institutions of higher learning. This group also provides resources for field workers to educate private property owners with information like the video on this page. COVID-19 brought many challenges, but also many opportunities to develop health and safety protocols that will last way beyond the pandemic, including the importance of mental health among our workers.

STYRENE SAFETY

PHASE 1 CIPP EMISSION STUDY

Published reports have questioned the safety of emissions from the CIPP process when using styrenated resin. NASSCO has gone to great lengths to ensure our workers and communities stay healthy through the funding of objective research. In Phase 1, the Center for Underground Infrastructure Research and Education (CUIRE) found previously published reports to be NON-CONCLUSIVE.

PHASE 2 CIPP EMISSION STUDY

Field studies in a variety of geographic locations – testing various liner dimensions, conditions, and worker exposure – were conducted by the Trenchless Technology Center at Louisiana Tech University (TTC) and resulted in specific recommendations for refrigeration/storage trucks and emission stacks including active air monitoring in trucks, 15-foot perimeters around exhaust manholes, and more.

PHASE 3 CIPP EMISSION STUDY

In Phase 3, TTC will evaluate the breakthrough time of various coating/resin combinations to create a mathematical model showing emission concentration versus time for different coatings and thicknesses. Validation of the model and testing the buildup of VOCs inside a liner transport truck at a wet-out facility will also be measured. Final report is expected in early 2022.
