12.2.5.1-1 Heat Stress

The level of physical activity and required protective clothing, as well as temperature and humidity, should be considered when assessing the danger of heat exposure.

Additional Information:
Important considerations are the amount of metabolic heat being generated by the worker and the restriction of evaporative heat loss associated with protective clothing. Workers' abilities to withstand heat will also differ based on their physical conditioning and degree of acclimatization.
