Course Overview: 

This course follows Sampling and Monitoring of Workplace Hazards (Parts 1 and 2) course held on November 18, 2013 and February 17, 2014, respectively.

The aim of this course is to provide attendees with a fundamental understanding of sampling data interpretation.   This course will cover the types of information needed to effectively interpret the following:  sampling data effectively, typical terminology used in laboratory reports, and industrial hygiene reports.  Standard statistical methods for data analysis will be reviewed to enable participants to determine the significance and implications of the exposure monitoring assessment.

At the end of the course, participants will have gained understanding of how:

  • To interpret sampling data and laboratory reports
  • To assess industrial hygiene exposure monitoring and indoor air quality reports
  • Exposure assessment results are analyzed using standard statistical methods
