Effectiveness of Ice (Water) Packets Vests in Reducing Heat Stress.

Abstract

The auxiliary cooling provided over the torso area by each of two similar ice (water) packets vests was directly measured on a life-sized sectional manikin. These vests were worn with a combat vehicle crewman (CVC) ensemble plus a complete chemical protective (CW) suit. Cooling rates provided (watts) versus time were determined for a completely wet (maximal sweating) skin condition during heat exposure to three hot environments. The number of ice packets attached to a vest varied from 43 to 91 ice pacekts. When approximately 50% of the torso surface area is covered by ice packets, each additional ice packet added to the vest increases the torso cooling to a greater degree than an ice packet added to a vest with less than 50% torso surface area coverage. Interface temperature between two ice packets and the torso surface and the temperature changes inside one ice packet during and experiment, were also measured. (Author)
