Thermal Environment


Thermal comfort describes whether a person feels too hot, too cold, or just right. Maintaining a thermally comfortable work environment can improve the morale and productivity of workers. On the other hand, extremely hot or cold environments are places where temperatures are so high or low that they can cause heat-related or cold-related illness or injury to a person. Air temperature, as well as other factors, can contribute to creating an extreme temperature environment. Heat-related and cold-related illnesses and injuries can be fatal. Assessing the thermal environment of a workplace allows PCBUs to manage the risk associated with either of these issues.

Humans are warm-blooded organisms whose biochemistry fully functions in a tight window around 37.0 °C, with deviations of a few degrees resulting in serious consequences. Thermal stress from moderate temperatures is not uncommon and should be effectively managed. Activities at moderate temperatures where thermal stress may be an issue include bakeries, commercial kitchens, laundries, boiler rooms, cool stores, packhouses, etc. Safe & Sound has a range of advance measurement technologies to accurately assess and help you manage workplace thermal environments.

Thermal Comfort
  • Thermal comfort describes the human satisfactory perception of the thermal environment
Heat Stress
  • Heat stress occurs when our body is unable to cool itself enough to maintain a healthy temperature
Cold Stress
  • Cold stress occurs by driving down the skin temperature, and eventually the internal body temperature. When the body is unable to warm itself, serious cold-related illnesses and injuries may occur, and permanent tissue damage and death may result
