Lesson 4C – Metabolic and Environmental Risks

This lesson explains potential physical risks for operators working in an extreme industrial environment where exertion may be required, and how those risks can be managed and mitigated.

Learning Objectives
  • Explain the effects of heat and cold stress on operators
  • Describe how to mitigate heat and cold stress on operators
  • Describe what the IREQ index measures, and how it can be used
  • Explain how ISO 15743 can be used to mitigate cold stress
  • Compute and interpret WBGT given raw observations
  • Estimate the kcal/hr and NIOSH Recommended Exposure Limit (REL) for a particular work activity
  • Describe how Borg’s RPE can be used to assess exertion, and how it is related to heart rate
