Climate under impermeable protective clothing

The actual microenvironmental wet bulb and dry bulb conditions were measured with a remote sensor under impermeable encapsulating protective clothing (EPC) at two sites (shoulder and waist). Subjects ( n=16) worked for 30 min followed by 30 min rest up to 4 h at 350 W in three different ambient envi...

Zusammenfassung:The actual microenvironmental wet bulb and dry bulb conditions were measured with a remote sensor under impermeable encapsulating protective clothing (EPC) at two sites (shoulder and waist). Subjects ( n=16) worked for 30 min followed by 30 min rest up to 4 h at 350 W in three different ambient environments, 18.2°C, 22.3°C and 26.9°C WBGT. The mean (±S.D.) of the microenvironment for each of the three macro-environments was 27.9 (±1.6)°C, 30.3 (±1.6)°C, and 32.6 (±1.5)°C WBGT, respectively, yielding clothing adjustments of about 9.7°C, 8.0°C and 5.7°C WBGT.
