A study on comfort of the protective clothing with 3 layer structure for Korean firefighters
Korean firefighters work normally with work tools and air tank, which weigh 20 kg. In their doing heat generated from body and moisture produced by sweat become trapped inside the protective clothing. Those heat and moisture create heat-stress and physical fatigue, which hinder the work. In order to find out the optimal combination of materials, 3 kinds of protective clothing with 3 layers structure ware used. They had the same size and the same materials of outer shell (A) and thermal barrier (C). But only difference was material for moisture barrier: PU Membrane (B1), PTFE Membrane on Aramid Nonwoven (B2), and PTFE Membrane on Aramid Nonwoven and Spacer (B3). The membrane side of moisture barrier faced the outer shell. The subjects rested for 30 min, walked on a running machine with the velocity of 5.5 km/hr for 10 min, rested for 5 min, run on a running machine with the velocity of 10 km/hr for 10 min, and rested for 30 min. From the comparison of wear trials with the 3 kind of structural firefighters clothing, it indicates that the moisture dissipation of A+B2+C was highest, and A+B1+C and A+B3+C. And the heat dissipation of A+B+C and A+B2+C ware better than A+B3+C. The subjective comfort sensation of A+B2+C was the best, and because of heat and moisture trapped inside the protective clothing that of A+B3+C was uncomfortable. In the protective clothing with A+B3+C, heat generated through exercise and moisture produced by sweat remained long and caused discomfort, which should be first considered in the manufacturing of fire protective clothing.
