This webinar presents information for industrial hygienists on the process of evaluating spaces for odors. On occasion, the industrial hygienist is asked to find the source of a localized, transitory, or wide-spread odor in a facility. Most industrial hygienists have their go-to list of how to evaluate for the odors. While many odors fit typical categories that industrial hygienist​s evaluate for, other odors are outside the typical – and the industrial hygienist is left with a space with an odor and uncertainty of how to proceed. This webinar outlines a systematic process of how to evaluate the odors from collecting subjective and objective information, evaluating site conditions for potential sources, determining whether sampling is appropriate (and what to sample), appropriate controls, and interpreting results. As part of the investigation process presentation, a discussion of odor thresholds is included.

​Learning Objectives

Upon completion, participants will be able to:

  • Outline the process for evaluating odors
  • Discuss techniques for determining potential sources of odors
  • Identify appropriate sampling methodologies
