Heat Stress and Thermal Comfort Assessments
Workers who are too hot or too cold lose concentration, take shortcuts and may stop wearing their PPE properly. Heat stress can lead to dehydration, fainting, heat exhaustion and heat stroke, which can be fatal. Foundries, smelters, boiler rooms, bakeries, kitchens and confined spaces carry the highest risk.
