Title Effects of a novel ice-cooling technique on work in protective clothing at 28C, 23C and 18C WBGTs
Bibliographic information Jan./Feb. 1999, Vol.60, No.1, p.96-104. Illus. 24 ref.
Abstract A new ice cooling suit was tested that permits recharge of the ice cooling system without removal of protective clothing and thus risk of contamination of the wearer. The suit allows for frozen gel packets to be worn in pockets on the outside of the suit. At 28C and 23C, mean work times with the cooling system were significantly increased over work times without the cooling system. Mean work times at 18C were not significantly different. During rest, mean reductions in rectal temperature were greater with the cooling system. Mean heart rate calculated at the same point in both treatments was lower with the cooling system. This new design seemed to provide comparable cooling to conventional vests and also provides greater practicality for field use. Even in experimental form, the suit demonstrated increased productivity due to extended tolerance time. Topics: body-core temperature; chemical protective clothing; comfort criteria; evaluation of equipment; exercise tests; human experiments; protective clothing; thermal comfort.
