Data, Professional Judgment, and Modeling in Occupational Exposure Assessment

Johns Hopkins Education and Research Center for Occupational Safety and Health

December 8, 2020 |12:00-1:00pm Pacific

Presented By: Gurumurthy Ramachandran, PhD, CIH

12 - 1 PM PST | 2 - 3 PM CST | 3 - 4 PM EST

Webinar Details

Exposure underestimates are a professional and ethical issue for Industrial Hygienists. This presentation will discuss the lack of adequate monitoring data for decision-making in industrial hygiene (IH), the over-reliance on professional judgment, and the limitations of professional judgments. Learners will also explore the use of heuristics and mathematical models, and distributed low cost networks for monitoring. 

Learning Objectives

At the completion of this activity, the learner will be able to:

  • Discuss the implications of limited monitoring data and exposure underestimation in IH

  • Identify tools available to improve accuracy, including statistical analysis of small data sets, heuristics and checklists, and mathematical exposure models

  • Describe how low cost networks and/or computed tomography may change the IH paradigm and discuss associated ethical considerations
