PDC 422

Introduction to Human Health Risk Assessment





introductory | Credits: 8 CM Credit Hours / 0.8 CEU / 0.5 CMP
Sunday, May 22 | 8:00 AM – 5:00 PM
Limit: 60


Environmental Issues, Exposure Assessment Strategies, Risk Assessment and Management


Risk assessment is a vital component of the modern practice of industrial hygiene. Despite its importance, few industrial hygienists are formally trained as risk assessors or understand the underlying principles or practice of risk assessment. This PDC is designed to educate practitioners about the relationship between industrial hygiene and classical risk assessment methods and provide a solid basis for understanding the core elements of the risk assessment process. The course will give practicing industrial hygienists sufficient knowledge and practical training needed to perform a straightforward risk assessment related to occupational or environmental exposures to hazardous agents.


A general interest about the topic of risk assessment as it is applied in environmental and occupational settings

Learning Aids

Participants must bring a scientific calculator, laptop, OR tablet/iPad.

Value Added

Risk analysis methods and tools are important resources useful to industrial hygienists who are charged with making decisions regarding occupational health. A copy of the 2010, Wiley Publication, Patty’s Industrial Hygiene, Volume 2, Evaluation and Control, 6th Edition, Chapter 18, “Human Health Risk Assessment” will be provided.


Upon completion, participants will be able to:

  • Comprehend the traditional risk assessment paradigm defined by the National Academy of Sciences and U.S. EPA.
  • Explain primary algorithms and input values used to characterize human exposures and health risks.
  • Determine the nature of scientific uncertainty as it relates to risk assessment.
  • Understand the key similarities and differences between environmental and occupational risk assessment practices.
  • Discuss the relationship between risk assessment, risk communication, and risk management.
