Learn the key steps to performing a dermal exposure assessment, including qualitative, semi-quantitative, and quantitative approaches.

Real-world case studies, free interactive tools, and collaborative exercises will be used to guide your way.

Throughout the conference, you’ll get hands on experience with interactive tools that can assist you in in performing your own assessments. Between each session, you’ll have the opportunity to put the information and training from the previous session into practice by completing specific exercises. The anonymous participant responses and inputs shared at the beginning of each session will be used collaboratively to help build a successful approach to dermal exposure assessment by all participants.

This virtual conference will be held over the course of four days. Each day includes one two-hour session, so you can easily work around your busy schedule.

Course outcomes

Upon completion, students will be able to:

  • Identify common exposure judgment errors made with dermal risk assessments
  • Integrate methods to effectively address and correct common judgment errors
  • Utilize new and existing exposure assessment tools and strategies to make more effective and efficient risk management decisions
  • Implement modeling tools, (such as IHMOD, IH SkinPerm), heuristics and other tools to guide qualitative exposure judgments
  • Apply deterministic and probabilistic exposure models to real exposure scenarios
  • Conduct qualitative and quantitative dermal exposure assessments using the AIHA Dermal Exposure Assessment framework and tools
  • Incorporate dermal exposure assessments into a comprehensive strategy
  • Access free resources offered by AIHA and networks of dedicated occupational and environmental hygiene professionals

Who Will Benefit

This course is ideal for exposure assessment practitioners and OHS professionals who are interested in incorporating dermal exposure assessment into a comprehensive exposure assessment strategy.


Those registering should have a basic working knowledge of Excel and access to a macro-enabled 2003 or newer version of Excel to do practice exercises using the provided tools.
