Course Overview

  • Understand the effects of the thermal environment on people.
  • Learn to assess and control the risks associated with thermal stress

Learning Outcomes

You will learn to

  • Identify sources of thermal stress within the working environment.
  • Understand the nature of thermal strain on the body.
  • Make an assessment of the thermal environment through measurement and other methods.
  • Evaluate risk from exposure to thermal stress.
  • Suggest appropriate control methods for the thermal environment.

Course Format

Normally run as a 5 day taught course [minimum 45 hours including practical/demonstration sessions, lectures, tutorials, guided reading, overnight questions and examination]. There will be a 60 multiple choice question ‘open book’ examination with an allowed time of 120 minutes.
