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.

SPEAKERS:
Laura Hallett is a Senior Associate Health Scientist with Cardno ChemRisk. Her key practice areas at Cardno ChemRisk include: industrial hygiene, exposure assessment, hazard communication, aerosol technology, industrial safety and litigation. She enjoys mixing analytical work in the office with getting her hands dirty as a consulting industrial hygienist for petroleum refineries. She actively publishes in the peer-reviewed literature and one of her favorite studies involved a quantitative evaluation of consumer monitors to measure particulate matter in occupational environments. She holds an M.S. in Occupational and Environmental Health with a focus in Industrial Hygiene from the University of Iowa and a B.S. in Environmental Health Science from the University of Georgia.
Josh Maskrey is a Health Scientist with Cardno ChemRisk. His key practice areas at Cardno ChemRisk include: industrial hygiene, exposure assessment human health risk assessment, chemical and environmental analysis, industrial safety and litigation. He has expertise in the design and implementation of indoor air and environmental modeling approaches for clients. He actively publishes in the peer-reviewed literature and one of his favorite studies involved long-term air monitoring of volatile organic compounds at a school and residence located proximate to a hydraulic fracturing pad. He holds a B.S. in Chemical Engineering with a certificate in Nuclear Engineering from the University of Pittsburgh.
