The performance of the improved microclimate suit

An assessment has been made of a new improved microclimate jacket when worn by men working for four hours in a hot environment (wet-bulb temperature of 33,9�C and an air speed of 0,4 m/s) and at work rates of 35 Wand lOW. At the lower rate of work in heat, the use of microclimate suits maintained...

Zusammenfassung:An assessment has been made of a new improved microclimate jacket when worn by men working for four hours in a hot environment (wet-bulb temperature of 33,9�C and an air speed of 0,4 m/s) and at work rates of 35 Wand lOW. At the lower rate of work in heat, the use of microclimate suits maintained the rectal temperatures of the men at almost the same level as when they worked without that protection at normal room temperature (20�C). At the greater rate of work without protection, the men's rectal temperatures rose to 40�C within two to three hours, so that they could not complete four hours of work. When they wore microclimate suits, they easily completed four hours of work, and their rectal temperatures were lower than when they worked at the lower rate without protection.
