Chemical workers are often required to wear protective chemical suits while working outdoors in the heat. The purpose of this study was to quantify heat exposures by obtaining thermal data inside chemical suits. A secondary aim was to validate the effectiveness of Lascar sensors as a means to estimate wet bulb globe temperature (WBGT). Lascar thermal data loggers were used to collect personal (inside the suit) and positional thermal data. A conventional Quest Temp heat stress monitor was used to verify the accuracy of WBGT predictions made from Lascar data. It was concluded that ambient data could be used to predict thermal conditions inside a Simplair A.E. Tank Suit (C-suit) and that Lascar data loggers can be used to predict WBGT values from humidity and temperature data. The Lascar loggers are small and can be worn inside protective clothing.
