This webinar will share ways that Industrial Hygienists can improve the accuracy of their exposure assessments by using a deterministic modeling tool – with case studies that demonstrate real-world applications involving mixtures and complex scenarios. Case studies will also demonstrate how to leverage existing exposure monitoring data through the use of the Structured Deterministic Model (SDM 2.0) to assess exposures for which monitoring data are not available. Included is an overview of the SDM 2.0 software, and application to several case studies.

SDM2.0 is an Excel-based, user-friendly tool for estimating airborne concentrations that represent potential occupational inhalation exposure to volatile and semi-volatile chemicals and chemical mixtures, aerosols, particulates, and fibers. It includes expanded functionality compared to its predecessor, the Checklist Tool, and a more visually informative report page. SDM 2.0 exposure assessment capabilities include the following:

  • Assesses exposure of overall mixtures and their individual chemical components
  • Assess exposure under non-ambient conditions
  • Expands exposure control category (ECC) 4 into 5 additional categories based on exposure and expands the health risk ranking (HRR) categories from the current 5 levels to seven levels. These modifications greatly enhance risk assessment, risk management, and risk communication efforts.
  • The tool includes a chemical database comprised of over 600 chemicals allowing the practitioner to populate required input fields that had to be populated manually in the prior checklist tool. And it includes a user chemical database that allows the user to include chemicals unique to their specific applications.
  • Provides a mechanism for utilizing existing quantitative measurements collected on a component of a mixture to calculate the corresponding exposure to the remaining non-measured components.
  • Saves the inputs and output as a 1-page report as a pdf

Learning Objectives

After this webinar, participants will be able to:

  • Describe the appropriate application of the SDM 2.0
  • Summarize the application of SDM 2.0 to commonly encountered workplace situations
  • Gain familiarity with how to use the SDM 2.0
