Exposure Assessment for Managers

A key element of Environmental and Occupational Health disciplines is the understanding and quantification of contaminant exposures. This course will first provide participants with a brief, but essential, introduction to how people react to environmental exposures. This introduction is followed by an orientation to exposure assessment theory to provide the participant with a sense of data quality in exposure assessments. Tools and approaches will be reviewed to introduce contemporary practices to the student so that they can apply this knowledge toward developing approaches for assessments of exposure in their own workplaces. Knowledge gained from this course may also be harnessed in the evaluation of 3rd party studies completed in support of programs for which the participant may be responsible for in their day-to-day work.

This is a required course in the Certificate in Occupational Health & Safety Management
