Exposure Assesment and Strategies

Scope of Work

Assessment of health hazards in the workplace, inhalation exposure modeling, dermal exposure modeling, product exposure assessment, and modeling.

Goals and Objectives

EASC is focused on providing the practicing professional with the tools necessary to demonstrate the value of industrial/occupational hygiene to workers and to the organization they work for through the use of professional knowledge, judgment, and tools that result in high-quality exposure assessments while reducing the time and resources required to decide the exposures.

Membership Diversity

The committee comprises a diverse group of industry, government, and academia professionals with various academic qualifications and experiences. There are many ways to participate in the EASC, e.g., work on a project team, teach a PDC, organize a roundtable, or work on the production of a white paper or textbook.

Advocacy and Influence

The EASC reviews and provides comments (through the AIHA) on pending regulatory and current occupational health and safety issues.


The EASC provides tools and training to improve the understanding and application of:
• Mathematical Modeling of Chemical Inhalation Exposures
• Deterministic Exposure Data Analysis Techniques
• Probabilistic Exposure Data Analysis Techniques
• Bayesian Decision Analysis for Exposure Acceptability
• Downstream Product Exposure Assessment
• Dermal Exposure Assessment
• Sampling Strategy Development
• Approaches to Improved Professional Judgment

Operational Excellence

The EASC Committee is a recognized model for operational excellence within the AIHA. The Committee is composed of dedicated and energized professionals and is a recognized source of exposure to scientific information for the occupational environment. The Committee is committed to outreach and development of future practicing industrial hygiene professionals, expanding AIHA membership, and educating the general public on the practice of industrial hygiene.

The following software tools provide the practicing industrial hygienist with quick and easy access to the information necessary to evaluate exposure profiles and determine whether the exposures are acceptable or unacceptable or if more data is needed to determine acceptability.

Current Projects

1. Development of an entry-level case study-based modeling book.
2. Taking up the 5th edition revision of the Exposure Assessment Strategies Book.
3. Bringing new instructors into our highly rated PDCs.
4. Working on an Exposure Assessment chapter for a book on IH Metrics.
5. Beta testers to create and maintain a national IH/OEHS research-to-practice agenda.
6. Supporting improvements to The Checklist tool.

Project Teams

Collaboration Efforts

We collaborate with exposure control banding and other groups as requested.

Awards and Recognition

  • Rising Star Award (2022)
  • Outstanding Volunteer Group (2022, 2019, 2016, 2015, 2014, 2013, 2012, 2011, 2010, 2008)

Group dynamics

Our members range from students to mid-career professionals, with a strong mix of industry, academia, government/military, and consulting. You can choose the level of involvement that fits your availability and earn CM points by:

  • Join a project team and learn from each other while producing real-world solutions and tools to protect the health and safety of workers around the world.
  • Participate in quarterly committee meetings—provide feedback, recommend exploring areas, and communicate collaboration opportunities.
  • One-and-done micro-volunteering tasks as the needs arise.
  • #IAMIH Challenge—public awareness and attracting the next generation of IH/OEHS professionals.
  • Mentorship and professional development.
  • Leadership development (serving as an officer of the group, project team leader).

Qualifications to Join

Members must be an AIHA member in good standing. If you are interested in learning more about membership, please visit https://www.aiha.org/membership.

(For the Practicing Industrial Hygienist)

Software tools have been developed to provide the practicing industrial hygienist with quick and easy access to the information necessary to evaluate exposure profiles and determine whether the exposures are acceptable or unacceptable or if more data is needed to determine acceptability. The tools are all free and are regularly updated. Several are available in multiple languages. Access these tools.

Legal Disclaimer: These tools were developed by volunteers over the years and are not copyrighted by them to our knowledge. While AIHA's logo appears on at least some of them, the Association does not control ownership rights. As directed by legal counsel, AIHA cannot enter into any agreements with third parties to produce derivative works (e.g., translations into other languages) unless the original authors assign rights under separate agreements.
