When Exposure Data Isn’t Available: Making Defensible EHS Decisions with Exposure Modeling
Already registered? Click here to log in.
Summary
Industrial hygienists and EHS professionals are often required to make critical exposure assessment decisions before sufficient air monitoring data are available. Whether evaluating a new process, determining respiratory protection requirements, allocating limited sampling resources, or addressing emerging chemical risks, waiting for additional data is not always an option.
In these situations, exposure modeling can provide valuable insights that help organizations make more informed and defensible decisions while prioritizing future monitoring efforts.
In this webinar, DEKRA industrial hygiene experts will demonstrate how exposure modeling can be applied in real-world workplace scenarios to:
- Prioritize tasks and operations for air monitoring
- Identify potential exposures during new or changing processes
- Support preliminary respiratory protection decisions
- Estimate respirator cartridge service life
- Improve efficiency when industrial hygiene resources are limited
Attendees will also learn the strengths and limitations of exposure modeling, how to interpret model outputs appropriately, and where modeling fits within a comprehensive industrial hygiene exposure assessment strategy.
Through practical examples and case studies, participants will leave with actionable approaches they can apply immediately within their own EHS and industrial hygiene programs.
Attendees will learn how to:
- Determine when exposure modeling can support an industrial hygiene exposure assessment.
- Use modeling to prioritize air monitoring and make better use of limited IH resources.
- Apply modeling to respiratory protection decisions and cartridge service life estimation.
- Understand model limitations and interpret results appropriately when making risk-based decisions.
- Integrate exposure modeling into a broader risk-based exposure assessment strategy.
