The topic of styrene safety has garnered a lot of attention in recent years. For more than a decade the effects of styrene cure water and condensate have been documented on receiving waters. Since 2017 academic research and customer concerns about CIPP acute and chronic health concerns has brought this issue to the forefront for suppliers, contractors, engineers, and owners. As the CIPP industry looks forward to the next 50 years of providing effective rehabilitation of our aging infrastructure, a better understanding of styrene emissions is an idea whose time has come. NASSCO is committed providing sensible best practices that promote worker safety while funding research to evaluate the challenge and establish a scientific basis for future recommendations.
