Abstract

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[deg]C, 22.3[deg]C and 26.9[deg]C WBGT. The mean (+/-S.D.) of the microenvironment for each of the three macro-environments was 27.9 (+/-1.6)[deg]C, 30.3 (+/-1.6)[deg]C, and 32.6 (+/-1.5)[deg]C WBGT, respectively, yielding clothing adjustments of about 9.7[deg]C, 8.0[deg]C and 5.7[deg]C WBGT. Significant differences (pRelevance to industryAn accurate estimation of environmental heat stress under protective clothing is needed. Presented is a practical method for laboratory and field estimations of potential heat strain under protective clothing.
