Abstract

Purpose : This study aims to seek out the risk of low-temperature burns and fire. Method : Hot vests are connected by higher voltage than walking voltage. Results : Accordingly, the possibility of low-temperature burns and fire was proved high. It was also shown that hot vests with relatively lower resistance on heat rays reached a higher temperature as the same voltage was applied. Conclusion : There are some problems with hot vests because they do not have any safety devices like a thermostat or a timer to prevent temperature increasing rapidly. For the purpose of reducing the risk of low-temperature burns and fire, setting the standard of the minimum resistance temperature and regulating the use of heat rays with lower resistance are necessary.

연구목적 : 본 연구는 최근 많이 이용하고 있는 발열조끼에 의한 저온화상과 화재위험성 도출을 목적으로 한다. 연구방법 : 사용전압보다 더 높은 전압에 발열조끼를 연결하는 실험을 실시하였다. 연구결과 : 재현실험한 결과 높은 저온화상과 발화위험성을 알 수 있었다. 또한 같은 전압을 인가했을 때 상대적으로 열선의 저항값이 더 낮은 발열조끼 제품이 더 높은 온도에 도달한다는 것도 알 수 있었다. 결론 : 발열조끼는 온도조절장치나 타이머가 존재하지 않아 온도가 급격히 올라갈 경우 안전장치가 없다는 문제점이 있다. 따라서 화재나 저온화상의 위험성을 줄이기 위해서는 열선의 최소저항값 기준을 설정하고, 낮은 저항값을 가지는 열선 사용의 규제가 필요하다.
