N/A
Temperature is a fundamental physical parameter in occupational health and safety, with both heat and cold extremes posing significant hazards to workers. Heat stress occurs when the body's thermoregulatory system is overwhelmed by a combination of metabolic heat generation and environmental heat load, potentially leading to heat cramps, heat exhaustion, and life-threatening heat stroke. Cold stress occurs in outdoor winter work, cold storage, and refrigeration environments, causing hypothermia and frostbite. Industrial hygienists assess thermal environments using dry bulb temperature, wet bulb globe temperature (WBGT), and other indices to evaluate heat and cold strain and develop protective controls.
Temperature monitoring identifies heat stress risks on job sites where workers are exposed to high ambient temperatures, radiant heat, or physically demanding conditions. Rent WBGT monitors and wearable heat stress sensors from RAECO Rents for construction, manufacturing, warehousing, and outdoor operations. All instruments are well maintained, annually calibrated, and functionally checked before shipment, with technical support to help you choose the right setup for your monitoring plan.
