Purpose and Goals
The purpose of this training module is to provide a management level training program that focuses on
the recognition, evaluation and control of heat related illnesses. The heat stress recognition and
control program should be an integral part of a company’s safety and health management system and
emergency response plan. The management system provides the frame work for the design,
development, and deployment of this training program. Two other training modules were developed for
Foreman and workers with the emphasis more on the recognition of signs and symptoms and the role
they play on an effective emergency response plan.
The training material is founded on OSHA’s Campaign to Prevent Heat Illness in Outdoor Workers” web
site as well as a guide that was published by
CDC/NIOSH in 1986 entitled “Occupational Exposure to Hot Environments” NIOSH 86-113 found at We strongly suggest that you become very familiar
with this material and use as many of the examples as you can fit into your own program that is tailored
to your needs and objectives. The resource section below also contains useful web sites and documents
that you will need as a safety and health professional who regularly assesses and evaluates worker
exposure to hot environments.
This training program is intended to be flexible from a time and topic perspective. Know your audience
and level of expertise. If you do not use or plan to use a particular measurement system on your job
site then you could omit those slides. If you use a method not mentioned in the program then create
new slides. A case in point is the use of Wet Bulb Globe Temperature method for developing work/rest
regimens. Some sites use it but others may rely on the Heat Index alone.
Seminar Objectives
Upon completion of this topic students should be able to:
1. Understand the severity of heat related illnesses and fatalities in Industry
2. OSHAs Policy on Heat Stress
3. Describe the risk factors for heat-related illness.
4. Describe the different types of heat-related illness, including how to recognize common signs
and symptoms and basic first aid
5. Describe the common control practices and methods to reduce the risk of heat related worker
illnesses and injuries.
6. Describe assessment tools used on the job site
7. Discuss the importance of acclimatization, how it is developed, and how your worksite
procedures address it.
8. Describe the procedures for responding to possible heat-related illness through an effective
safety and health management system.
