Risk Committee


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.  

Topics and Activities  


Electronic Cigarettes in the Indoor Environment

The E-Cig Project Team initially developed an AIHA white paper that describes the potential exposures and health risks associated with the use of electronic cigarettes. The white paper reviews current scientific information, evaluated the effects of chemicals used in e-cigarettes and emitted from them, and indicates that while e-cigarettes may appear to provide a 'safer' alternative to tobacco cigarettes, these products can emit airborne contaminants that may affect both the user and people nearby.  

The E-Cig Project Team continues to monitor the evolving science addressing emissions and health effects from electronic cigarettes, and is working on a review article with updated information for the Journal of Occupational and Environmental Hygiene.  ​

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.
