“A crisis of regulations” is haunting manufacturers worldwide: governmental standards don’t exist for many workplace and environmental factors, while most of the existing exposure limits are not health-based. Risk assessment becomes a viable alternative to regulatory paradigm, allowing industry professionals to evaluate new and emerging hazards and establish internal occupational exposure limits. This approach follows the “precautionary principle,” while employing the best available scientific information to prioritize risks and ensure occupational and public health improvement. This PDC will take participants for an intensive, hands-on one-day ride exploring how and when semiconductor industry personnel can use advanced risk assessment methods in their practice. The objective of the class is to demonstrate different methods and techniques used for risk assessment purposes. Structural components of the risk assessment paradigm (hazard identification, exposure assessment, dose-response assessment, and risk characterization) will be described from a practical point of view. The participants will learn via class exercises how to obtain & interpret risk metrics, including absolute & relative risk, attributable risk fraction, unit risk, slope factor, and reference concentration and dose.The audience will participate in interactive exercises, including a statistical risk simulation, demonstrating the probabilistic nature of hazards and health outcomes. The class materials will be based on case studies intended to refresh the audience’s knowledge on hazardous agents specific to the industry, including, arsine, phosphine, methylene chloride, hydrofluoric acid (HF), tetramethylammonium hydroxide (TMAH), and engineered nanoparticles.
