Ergonomics of the Thermal Environment-Assessment of Heat Stress Using the WBGT (Wet Bulb Global Temperature) Index

Wet chamber sphere temperature (WBGT) is one of the measurements carried out by Environmental Laboratories within the scope of Occupational Hygiene - Thermal Comfort Measurements, approved by İSGÜM, which is defined as an experimental index showing the heat pressure that the person is exposed to.

In the construction of Occupational Hygiene Thermal Comfort Measurements, PMW, PPD and WBGT values ​​are determined and evaluated within the scope of the standards determined by İSGÜM. After determining PMV (Estimated Average Vote) and PPD (Personal Dissatisfaction Percentage) within the scope of TS EN ISO 7730 standard, the comfort level is estimated with a 7-point scale.

The desired result after Thermal Comfort Measurements is between -2 and +2. If the value obtained is above +2, the “Wet chamber globe temperature (WBGT)” value is tried to be determined based on the ISO 7243 standard.

It is aimed to evaluate the heat stress in work environments by determining the wet chamber sphere temperature (WBGT) value. In general, PMW, PPD and WBGT measurements are used to determine the degree of exposure of employees to hot and cold.
