Eight firefighters participated in eight conditions consisting various combinations PPE weighing from 7.8 14.9 kg (fully equipped with all PPE, FullPPE; FullPPE without a self-contained breathing apparatus, NoSCBA; helmet, NoHelmet; gloves, NoGloves; boots, NoBoots; Full bunker...

Abstract This study investigated the thermal insulation of an air-cell pack embedded jacket and down jackets tounderstand potential as a filler for winter outdoor wear. A manikin measuredthe following jackets: HD (heavy jacket, total weight (Tw) 750g, goosedown (Dw) 350g), LD (light Tw 560g, Dw 140g), AF (air-cell jacket,Tw 490g, trunk goose in was replaced to air cell), F (film 469g, but removed airin from AF), Control (control 438g, film fromthe F). Thermal insulations each experimental...

The present study aimed to investigate the behaviors and attitudes about heating cooling energy saving indoor clothing habits according occupation gender. 509 people participated in questionnaire which consisted of 47 questions. results showed that 1) were more dissatisfied with summer temperature (26~28℃) compared winter (18~20℃) recommended by Korean government save airconditioning energy; 2) no gender difference was found temperature, whereas females expressed experiences being cold than...

This study was to develope the pesticide-proof clothes(PPC) for fruit-grower which has been well known over applied agricultural chemicals. The ergonomic evaluation of PPC were tested in two ways. Male adults volunteered tests evaluate safety pesticide field and thermal comforts climate-chamber(<TEX>$30^{\circ}C$</TEX>, 60%R.H.). made 4 different fabrics. Two them on market(coated non-woven coated nylon). Others water-repellent treatment waterproof film by developed polyester. conducted...
