본 연구는 반복적 소방활동이 신체에 미치는 영향을 분석하여 소방공무원의 안전을 위한 기초자료 제공을 목적으로 한다. 실험온도 WBGT$20^{\circ}C$(흑구온도 $27.2^{\circ}C$, 건구온도 $26.2^{\circ}C$, 습도 26.7%)에서 작업강도 9 METs(6 km/h, 10%)로 실험 15분(Ex1), 휴식 15분(Rest), 실험 15분(Ex2)의 순으로 소방전공 대학생(9명; $24.3{\pm}0.71$세)을 대상으로 반바지와 소방용 보호장구를 착용한 경우의 비교실험을 수행하였다. 실험결과, 소방용 보호장구를 착용한 경우에서 평균피부온도차(214.0%), 고막온도차(175%), 심박수(20.5%), 호흡수(14.2%), 운동자각도(50.0%), 온냉감(12.0%)과 체중감소(60.0%)가 통계적으로 유의하게 높게 나타났으며, 반복적 소방활동이 신체에 많은 영향을 미치는 것으로 연구되었다.

The aim of study intends to investigate the effects of repetitive firefighting on human body and to provide the basic data for the safety of firefighter. The results of the study are as follows; On two separate occasions under ambient temperature WBGT $20^{\circ}C$(Globe Temperature $27.2^{\circ}C$, dry bulb temperature of $26.2^{\circ}C$, relative humidity 26.7%), nine firefighting majoring students(n=9; age $24.3{\pm}0.71$) completed two 15 min treadmill walking(Ex1, Ex2) 9 METs(6 km/h, 10%) separated by a 15 min recovery period(Rest), during which students were either wearing firefighting protective equipment or wearing shorts(control). After experiments, mean skin temperature change(214.0%), tympanic temperature change(175%), heart rate(20.5%), respiration rate(14.2%), RPE(50.0%), thermal Sensation(12.0%), weight loss(60.0%) are statistically significantly higher in the case of wearing firefighting protective equipment. It is concluded that physiological responses of human body varied considerably and reflected by repetitive fire fighting.
