Styrene Emissions in Steam-Cured CIPP: A Review and Comparison of Multiple Studies

摘要

Recent research by Matthews et al. at the Louisiana Tech University Trenchless Technology Center (TTC) regarding styrene emissions produced during steam-cured, styrene-based cured-in-place pipe (CIPP) installation was compared to data from six relevant, independent studies. As part of this analysis, data in the reviewed studies were compared to exposure guidelines published by the Environmental Protection Agency (EPA), National Institute of Occupational Safety and Health (NIOSH), and Occupational Health and Safety Administration (OSHA). Measurement methodology and goals were considered and briefly described in the analysis. Finally, this paper highlights differences and similarities in the conclusions and measurements of the reviewed studies while searching for and identifying conclusions and trends that are common across the reviewed studies.
