고온환경에서 소방방화복 착용시 작업강도가 신체에 미치는 영향 = Effects of Workload on Human Body wearing Firefighting Protective Clothing in High Temperature

국문 초록 (Abstract)

본 연구는 고온환경에서 소방방화복 착용시 작업강도가 신체에 미치는 영향을 분석하여 소방공무원의 안전을 위한 기초자료 제공을 목적으로 한다. 고온환경 WBGT <TEX>$30^{\circ}C$</TEX>(흑구온도 <TEX>$40.5^{\circ}C$</TEX>, 건구온도 <TEX>$40.4^{\circ}C$</TEX>, 습도 34.9%)에서 작업강도 4 METs와 8METs로 20분간 소방전공 대학생(8명; <TEX>$21.9{\pm}0.35$</TEX>세)을 대상으로 실험한 결과, 고막온도차(120%), 심박수(27.5%), 호흡수(21.6%), 운동자각도(27.9%), 온냉감(41.9%)과 체중감소(200%)는 통계적으로 유의하게 높게 나타났으며, 평균피부온도차는 유의한 차이가 나타나지 않았다. 이상의 결과 고온환경에서의 소방방화복 착용은 신체에 많은 영향을 미치는 것으로 연구되었다.

The aim of study intends to investigate an effects of workload on human body wearing firefighting protective clothing in high temperature and to provide the basic data for the safety of firefighter. The results of the study are as follows; After firefighting majoring students(n=8; age <TEX>$21.9{\pm}0.35$</TEX>) performed workload of 4 METs and 8 METs in high-temperature environment WBGT <TEX>$30^{\circ}C$</TEX>(Globe Temperature <TEX>$40.5^{\circ}C$</TEX>, dry bulb temperature of <TEX>$40.4^{\circ}C$</TEX>, relative humidity 34.9%) during 20-minute, tympanic temperature change(120%) heart rate(27.5%), respiration rate(21.6%), RPE(75.6%), thermal Sensation(41.9%), weight loss(200%) are statistically significantly higher and skin temperature change is not statistically significant. It is concluded that physiological responses of human body varied considerably and reflected by high temperature.
