Climat change and occupational heat stress: methods for assessment
(2010) In Global Health Action p.1-5- Abstract
- Background: Presumed effects of global warming on occupational heat stress aggravate conditions in many
parts of the world, in particular in developing countries. In order to assess and evaluate conditions, heat stress
must be described correctly and measured correctly.
Objective: Assessment of heat stress using internationally recognized methods.
Design: Two such methods are wet bulb globe temperature (WBGT; ISO 7243) and predicted heat strain
(PHS; ISO 7933). Both methods measure relevant climatic factors and provide recommendations for limit
values in terms of time when heat stress becomes imminent. The WBGTas a heat stress index is empirical and
widely recognized. It... (More) - Background: Presumed effects of global warming on occupational heat stress aggravate conditions in many

Objective: Assessment of heat stress using internationally recognized methods.
Design: Two such methods are wet bulb globe temperature (WBGT; ISO 7243) and predicted heat strain
(PHS; ISO 7933). Both methods measure relevant climatic factors and provide recommendations for limit
values in terms of time when heat stress becomes imminent. The WBGTas a heat stress index is empirical and
widely recognized. It requires, however, special sensors for the climatic factors that can introduce significant
measurement errors if prescriptions in ISO 7243 are not followed. The PHS (ISO 7933) is based on climatic
factors that can easily be measured with traditional instruments. It evaluates the conditions for heat balance
in a more rational way and it applies equally to all combinations of climates.
Results: Analyzing similar climatic conditions with WBGT and PHS indicate that WBGT provides a more
conservative assessment philosophy that allows much shorter working time than predicted with PHS.
Conclusions: Both methods should be used and validated worldwide in order to give reliable and accurate
information about the actual heat stress. (Less)
