Heat Stress Environments

Heat stress environments are not limited to the outdoors. Heat stress and illness can affect workers who are working both indoors and outdoors. Operations involving high temperatures, radiant heat sources, high humidity, direct physical contact with hot objects, or strenuous physical activities have a high potential for inducing heat stress in employees.

Workloads or locations that are likely to increase a worker's core temperature higher than 100.4° Fahrenheit increases the risk of heat stress. Workers who are exposed to job-related high temperatures and conditions may also be required to wear PPE that can protect them, but the additional weight of PPE can also increase the body temperature of the worker. It is important to understand the risks associated with each work environment.
