The purpose of this study was to evaluate comfort functions while wearing firefighters’ protective glovesin dry and wet conditions at 70oC air temperature with radiant heat. Four types of firefighting gloves from Korea,Germany, United States, and Japan were evaluated in both dry and wet conditions by eight male firefighters. Firefightersput their hands and forearms wearing gloves into a hands-radiant chamber that maintained at an air temperature of70 ± 2oC (Ta) and globe temperature 106oC (Tg). During the exposure, subjects followed a fixed protocol of manualmovements and stopped the exposure when they felt being intolerable. Results showed that completion time wasextended by 6 min on average when gloves got wet and 15 min for the Japanese gloves was extended when comparedto its dry condition (p<.001); microclimate humidity on the palm at the last stage was greater for wet conditions thandry conditions in the all gloves; and skin temperatures on mid-fingertip, palm, and hand were significantly lower forwet conditions than dry conditions especially for Japanese gloves (p<.001). These results indicate that the exposuretime without thermal pain to radiant heat could be extended by wetting gloves during the low radiant heat exposure.
