Risk Assessment Committee

Mission and Goals 

The mission of the committee is to support and promote the application of human health risk assessment to better understand and control the hazards found within workplace and environmental settings.
  • Goal 1: Promote the advancement of risk assessment within the field of industrial hygiene to better understand and control the hazards found within workplace and environmental settings.
  • Goal 2: Organize and develop state-of-the-art presentations, symposiums, and continuing education courses on the application of risk assessment within the workplace. 
  • Goal 3: Develop collaborations with other AIHA committees and external organizations to promote the use of the principles of risk assessment to evaluate the risks of exposures to chemical, biological and physical agents.

Toxic Substances Control Act (TSCA) of 2010

The Toxic Substances Control Act of 1976 provides the US Environmental Protection Agency (EPA) with authority to require reporting, record-keeping and testing requirements, and restrictions relating to chemical substances and/or mixtures.  Certain substances are generally excluded from TSCA, including, among others, food, drugs, cosmetics and pesticides. TSCA addresses the production, importation, use, and disposal of specific chemicals including polychlorinated biphenyls (PCBs), asbestos, radon and lead-based paint. 
In July 2010, new legislation was introduced that would amend the Toxic Substances Control Act of 1976 to ensure that the public and the environment are protected from risks resulting from chemical exposure.  A few of the risk assessment related reforms included within the TSCA of 2010 are:
  • Establishes a framework to ensure that all chemical substances to which the American people are exposed will be reviewed for safety and restricted where necessary to protect public health and the environment.
  • Requires the chemical industry to develop and provide to the EPA essential data, and improves EPA’s authority to compel testing where necessary.
  • The reduction of the use of animals in chemical testing.
  • Ensures that non-confidential information submitted to EPA is shared with the public and that critical confidential information is shared among regulators, with states, and with workers in the chemical industry.
  • Establishes an expedited process for EPA to reduce exposure to chemical substances that are known to be persistent, bioaccumulative, and toxic.
  • Creates incentives and a review process for safer alternatives to existing chemicals, promoting innovation and investment in green chemistry.

Human Health Risk Assessment Chapter in 6th Edition of Patty’s Industrial Hygiene and Toxicology

Publication by Wiley Publishing Company of Patty's Industrial Hygiene and Toxicology - 6th Edition is expected in 2010.  A new chapter titled Human Health Risk Assessment was introduced and developed for this particular 6th Edition. While the chapter was spearheaded by Chris Laszcz-Davis, its team of contributors includes a broad cross section of EH&S experts in exposure assessment, risk assessment, toxicology, finance and legal issues who hail from government, industry, academia and consulting. The Human Health Risk Assessment chapter team contributors include Fred W. Boelter, Frank Hearl, Dr. Michael Jayjock, Chris Laszcz-Davis, Perry Logan, Cristina Ford McLaughlin, Dr. Mary O'Reilly, Thomas Radcliffe, Jr., and Mark Stenzel. Boelter, Jayjock, Laszcz-Davis and O'Reilly are members of AIHA's Risk Assessment Committee.

Risk Assessment Symposiums at PCIH

Since 1997, the Risk Assessment Committee has sponsored a total of 8 symposiums at Professional Conference of Industrial Hygiene (PCIH).  These symposiums focus on high priority issues related to the application of the science and art of risk assessment within the practice of industrial hygiene.
