본 연구는 가스보일러 CO 누출사고 경감방안에 관한 연구로서, CO 경보기 및 콘덴싱 보일러 의무화 설치 및 지원금 방법을 제시하였다. CO 중독을 예방하기 위해 CO 경보기를 의무 설치하여야 하며 현재 국산 CO 경보기의 가격이 약 4만원이며, 기초수급생활자 및 일반가정 400만 가구 대상으로 3 년 간 1,000억원의 금액이 소요됨을 제시하였다. 기초생활수급자 20만원, 일반가정 10만원, 400만 가구를 지원해주면, 3 년 간 5,000억원의 금액이 소요되며, 재정마련은 연간 100만대 판매되는 보일러를 콘덴싱 보일러로 의무화 시 년 간 약 2,000억원의 에너지 절감이 되며, 콘덴싱 보일러의 수명이 10년으로 했을 때 총 2조원의 에너지 절감비용이 생긴다. 그 중 6,000억원의 비용은 CO 경보기 및 콘덴싱 보일러 설치 지원비로 사용하며, 10년간 국내가스사고 CO 누출사고 50% 이상의 사고를 경감할 수 있을 것으로 제시하였다.

This work is concerned with a plan for preventing accidents of CO gas leak from gas boilers, involving the enforcement of installations of both CO alarm system and condensing boilers, and financial support of government grants. If amongst 1,460,000 beneficiaries of basic livelihood security, one million households in use of gas boilers receive 3-year support of 200,000 won, the difference of prices between common and condensing boilers, the government grants would be 2,000 billion won. If 3 million common householders are in 3-year support of 100,000 won, government grants would be 3,000 billion won. Therefore, 3-year grand total of government grants would be 5,000 billion won. Finance for government grants can be purveyed from energy saving; yearly 2,000 billion won of energy saving by enforcing to replace one million existing boilers with condensing boilers, leading to 2 trillion won of energy saving for 10 years. In this way, 6,000 billion won of 3-year grand total of government grants for CO alarm system and condensing boilers can be purveyed. The rest amount would be fundraised for energy savings. We claim that our proposal can make an achievement of more than 50% reduction of CO leak accidents during 10 years.
