Heat Stress Monitoring Systems

Heat stress includes a series of conditions where the body is under stress from overheating. This dangerous condition can be prevented by vigilant environmental monitoring and adherence to recommended guidelines.

As environmental temperature and humidity increase, there is an increase in the heat stress that is placed on the working individual. Working in the heat causes the body to rely on evaporation of sweat from the skin as the primary method of dissipating heat that is produced by the working muscles. As humidity increases, the ability to dissipate heat through evaporation is hindered, thus causing the body to have an increased body temperature, which increases the risk of Heat Stress.1

Heat-related illnesses include heat cramps, heat exhaustion, heat rash, or heat stroke, each with its own symptoms and treatments. Symptoms can range from profuse sweating to dizziness, cessation of sweating, and collapse.2

Monitoring for Heat Stress

CWS offers two calculated measurements to help monitor heat stress: Wet Bulb Globe Temperature and Thermal Work Limits

Both systems incorporate ISO standard 150mm Black Globe Temperature Sensor in addition to typical meteorological parameters. Click the images below to learn more about each system.
