ABSTRACT
Thermal stress can arise from exposures to either hot or cold environments. For a wide variety of work environments it is common for there to be extremes as well as wide fluctuations in the temperature; because of this, it is important to understand thermal stress. This chapter will focus on the factors and parameters that are used to characterize thermal stress, and, in addition, will discuss the effects that these conditions can produce on individuals who, in the normal course of their work, may be exposed to them.
