주지된 바와 같이, 각 산업 현장 특히, 건설 현장 등에서는 용접을 필수적으로 실시해야 하므로 용접과 관련되어 용접사와 보조자 및 화재감시자 등의 3인 이상이 반드시 충원되어야 하며, 상기 화재감시자의 경우 항상 소화기를 휴대 또는 작업현장 주변에 구비해야 하고, 이를 관리해야 하는 임무를 수행하게 되며, 화재 발생시에는 상기 소화기를 이용하여 신속하게 화재를 진압하는 임무를 수행하도록 하고 있으나 작업 현장은 각종 공구와 많은 자재들이 있기 때문에 화재 발생시 소화기를 찾아서 사용하기가 매우 어려운 환경에 있다. 이로 인해 화재에 신속하게 대처하지 못하고 있어 대형화재로 이어지는 경우가 대부분이어서 막대한 재산 및 인명 피해가 발생하고 있는 추세이다.As is well known, since welding is essential in each industrial site, especially at a construction site, at least three people, such as a welder, assistant, and fire supervisor, must be recruited in connection with welding, and in the case of the fire supervisor, always use a fire extinguisher. It must be carried or equipped around the work site, and the task of managing it is performed. In the event of a fire, the fire extinguisher is used to quickly extinguish the fire, but the work site has various tools and many materials. Therefore, in the event of a fire, it is very difficult to find and use a fire extinguisher. As a result, it is not possible to quickly respond to a fire, and in most cases it leads to a large-scale fire, resulting in enormous damage to property and human life.

그래서, 화재를 신속하게 진압하기 위하여 분 발명인이 소화수단이 내장된 작업용 조끼(대한민국 특허등록 10-1853655호)를 개발하였던 바, 이의 구성을 도 1에 의거하여 상세히 설명하면, 겉감과 안감을 소정 형태로 재단 및 재봉하여 형성되며, 가슴부위의 겉감과 안감 사이를 접합시켜 소정 공간의 수납부(110)를 형성하고, 배부위의 겉감과 안감 사이를 접합시켜 소정 공간의 포켓부(120)를 일체로 형성하되, 상기 수납부와 포켓부가 연통되도록 통로가 형성된 조끼본체와(100); 상기 조끼본체(100)의 수납부(110)에 인출이 가능하도록 수납되며, 내부에 소화액 또는 소화분말을 5키로의 주입할 수 있도록 상부에 주입구(210)가 형성되고, 하부에는 고압가스가 유입될 수 있도록 유입구(220)가 형성되며, 상부 일측에는 분사구(230)가 일체로 형성된 하우징(200)과; 상기 조끼본체(100)의 포켓부(120)에 수납되고, 상기 통로를 통해 삽입되는 호스의 일단이 상기 하우징(200)의 유입구(220)와 연결되고, 상기 호스의 타단이 연결 고정되며, 소정 길이로 제공되는 고정끈의 일단에 장착된 손잡이로 이루어진 개폐수단(300)과; 상기 개폐수단(300)이 일측에 설치되어 개폐수단의 개방에 의해 상기 호스를 통해 하우징(200) 내부로 고압의 가스를 공급할 수 있도록 내부에 CO2가스가 압축,충진된 상태의 압축탱크(400)와; 상기 하우징(200)의 분사구(230)에 호스의 일단이 연결 고정되며, 타단에는 소화액 또는 소화분말이 넓게 분사되도록 하는 분사노즐(500);을 포함하되,상기 주입구(210)에 나사 결합될 수 있도록 별도의 마개(212)를 구비하여 상기 주입구를 개폐시켜 소화액 또는 소화분말이 외부로 흘러나오지 않도록 하는 동시에 상기 마개를 분리시켜 주입구를 통해 소화액 또는 소화분말의 재주입이 가능하도록 한 것이다.So, in order to quickly extinguish a fire, the inventor developed a work vest (Korean Patent Registration No. 10-1853655) with a built-in fire extinguishing means.
