IH Air Modeling Techniques for Exposure Estimation

ChemRisk industrial hygienists and engineers  will present on IH air modeling techniques for exposure estimation with a focus on the recently released IHMOD2.0 tool (published by Tom Armstrong, Daniel Drolet).

ABSTRACT:
​
This AIHA Pittsburgh local section presentation provides an overview of indoor air modeling techniques useful for developing exposure estimates. Reasons for using a model as an occupational health practitioner and the hierarchy of models, from simple to complex, are presented as introductory material. Two models, the well-mixed zone and two-zone models, are discussed and used as examples for later in the presentation. Techniques for gathering information about key model inputs including generation rates, ventilation parameters, and time-based parameters are presented. Probabilistic modeling is introduced as a tool for addressing uncertainty. The second half of the presentation introduces IHMOD2.0, a recently published Microsoft Excel®-based modeling tool created by Thomas Armstrong and Daniel Drolet. Modeling examples and case studies using IHMOD2.0 will be discussed.
