Education/Training + Get AlertsAfter nearly two years of extensive study, the Trenchless Technology Center at Louisiana Tech University has released its final report: Evaluation of Air Emissions From Polyester Resin CIPP With Steam Cure. The nearly 700-page report, available at www.nassco.org, details the measurement of styrene and other organic compounds at multiple CIPP installation sites across the country.
The report provides several recommendations and conclusions based on the survey data.
Liner transport trucks and storage units
• For those immediately entering the liner transport truck or storage unit, active air monitoring should be utilized at the initial opening of the truck or storage unit door to ensure a safe work environment.
• At the initial opening of the liner transport truck or storage unit door, suitable personal protective equipment should be worn by those immediately entering the truck or storage unit.
Emission stacks
• A perimeter of 15 feet should be implemented around exhaust manholes and emission stacks during curing. This perimeter could be entered for short amounts of time not exceeding five minutes. If this area must be entered for longer than five minutes, suitable PPE should be used.
• Emission stacks should be a minimum of 6 feet in height to enhance the dispersion of emissions and lessen the likelihood of workers entering the perimeter from having to cross into the plume even when wearing PPE.
The Trenchless Technology Center made further recommendations for future study including focusing on task-oriented worker exposure to emissions to identify certain tasks within the typical eight-hour shift window that could pose health risks; better understanding the dispersion of styrene from the liner truck after opening; and gathering more data to correlate the number of liners being stored on the truck, the liner sizes and the duration the liners have been on the truck with emission concentrations.
NASSCO has made additional, interim recommendations to keep workers and communities safe:
• Until more comprehensive recommendations are prepared, NASSCO recommends air monitoring by workers entering the liner transport truck or storage unit, either immediately after opening the unit door or after a designated wait time.
• Workers should wear suitable PPE based on the results of the air monitoring when entering the truck or storage unit.
Moving forward
NASSCO’s Technical Advisory Council is working closely with the association’s Health and Safety Committee to develop and/or modify safety guidelines based on the Trenchless Technology Center’s findings. Additionally, NASSCO has formed a CIPP Safety Workgroup to develop outreach and consider further research.
While NASSCO committees and work groups are typically open only to NASSCO members, the CIPP Safety Workgroup is an exception because we want all leaders aligned to CIPP technology, including academia, industry and others, to come together to help NASSCO set standards to keep our workers and communities safe.
