Heat exposure may occur in many workplaces. Furnaces, bakeries, smelters, foundries and heavy equipment are significant sources of heat inside workplaces. For outdoor workers, direct sunlight is the main source of heat. In mines, geothermal gradients and equipment contribute to heat exposure. Humidity in workplaces also contributes to heat stress. The key to preventing excessive heat stress is knowing the hazards of working in heat and the benefits of implementing proper controls and work practices. You’ll learn about all of these in this training.
