“겨울캠핑, 일산화탄소 중독 조심하세요!”

국립부경대학교와 부산소방재난본부는 공동으로 기획한 일산화탄소 발생 실험 실시 결과를 12월 7일 발표했다.

부경대 공동실험실습관과 부산소방재난본부는 매년 반복적으로 발생하는 캠핑장 일산화탄소 중독 사고의 위험성을 알리고 인명피해를 줄이기 위해 지난 3일부터 7일까지 3일간 부경대에서 캠핑용 난방기구 일산화탄소 발생 실험을 실시했다.

불완전 연소 시 발생하는 일산화탄소는 무색·무취·무미·무자극 특성으로 농도가 짙어져도 인지하기 어렵고, 산소 대비 헤모글로빈과 240배나 높은 친화도를 가지고 있어 저산소증을 유발한다. 특히 농도가 2,000ppm에 도달하면 사람이 1~2시간 만에 사망에 이를 수 있다.


한국소비자원의 지난해 발표한 자료에 따르면, 최근 5년간 발생한 캠핑장 안전사고 195건 중 ‘난방기기 및 취사기구 이용 중 발생하는 위해증상’이 60건으로 30.8%를 차지하는 것으로 나타났다.

부경대 공동실험실습관과 부산소방재난본부는 1.9m×2m×1.5m 크기의 텐트를 밀폐시킨 환경에서 난방기구 4종(숯·무시동히터·이동식부탄연소기·등유난로) 사용에 따른 일산화탄소 등 유해가스의 시간대별 농도 변화를 측정했다.

실험결과, 숯을 활용하는 화로는 참숯과 차콜 2가지 모두 실험 시작과 동시에 일산화탄소 농도 500ppm 이상으로 경보기가 작동했다. 참숯은 17분경 2,040ppm, 차콜은 2분 내 2,000ppm에 이르렀고, 14분경에는 5,000ppm으로 나타났다.

무시동히터는 배기구 접속부의 배기가스 누출을 가정한 상황에서 10분경과 시점에 산소농도가 안전한계(18%) 이하인 17.57%로 측정됐다. 이때 이산화탄소 농도는 0.28%였고, 40분 후에는 산소가 소모되면서 0.54%까지 급격히 증가했다. 경유 연소가스에는 산화질소 등 유해가스도 동시에 측정됐다.

2구형 이동식부탄연소기는 약 30분 후 산소농도가 17.3%로 안전한계 수치 이하로 낮아졌고, 일산화탄소 농도는 38분 이후부터 꾸준히 증가해 실험 후 70분경에는 253ppm까지 측정됐다. 등유난로는 일산화탄소의 농도가 지속적으로 높아져 실험시작 35분경까지 43ppm의 수치가 측정됐고, 산소는 10분후 17.7%, 50분후에는 14.7%까지 낮아졌다.

실험 분석 및 측정을 맡은 부경대 공동실험실습관 서용수 책임연구원은 “숯은 불완전 연소로 일산화탄소가 급격히 증가하고, 무시동히터는 활발한 연소로 산소부족을 일으킬 수 있다. 단시간이라도 탠트 내 난방기구 사용은 일산화탄소 중독, 질식의 위험이 매우 크다.”라고 말했다. <부경투데이>

"Beware of carbon monoxide poisoning while enjoying your winter camping!"

- PKNU and the Busan Metropolitan City Fire Disaster Headquarters announced the results of the CO level test of camping heaters

    

Pukyong National University and the Busan Metropolitan City Fire Disaster Headquarters announced on December 7 the results of their jointly planned carbon monoxide emission experiment.

    

To wake up the public about the risk of carbon monoxide poisoning accidents that occur repeatedly every year and to reduce losses of life, the Central Laboratory at Pukyong National University and the Busan Metropolitan City Fire Disaster Headquarters held a carbon monoxide level experiment for camping heating at Pukyong campus from the 3rd to the 7th, for three days.

    

Carbon monoxide generated during incomplete combustion is colorless, odorless, tasteless, and non-irritating, making it difficult to recognize even if the concentration increases. In addition, it has a 240-fold higher affinity with hemoglobin compared to oxygen, causing hypoxia. Especially, when its concentration reaches 2,000 ppm, a person can die in 1 to 2 hours.

    

According to data released by the Korea Consumer Agency last year, out of 195 safety accidents at campgrounds that have occurred over the past five years, 'Hazardous symptoms while using heating and cooking appliances' accounted for 30.8% of the 60 cases.

    

The Central Laboratory at Pukyong National University and the Busan Metropolitan City Fire Disaster Headquarters measured the change in concentration of harmful gases such as carbon monoxide by time period due to the use of 4 types of heating appliances (charcoal, parking heater, portable butane burner, kerosene stove) in an enclosed space with a tent measuring 1.9m×2m×1.5m.

    

As a result of the experiment, for both hardwood charcoal and charcoal, the alarm was activated at the carbon monoxide concentration of 500ppm or more at the same time as the experiment started. Hardwood charcoal reached 2,040ppm at 17 minutes, charcoal reached 2,000ppm within 2 minutes, and 5,000ppm at 14 minutes.

    

In the case of the parking heater, the oxygen concentration was measured to be 17.57%, which is below the safe limit (18%), when 10 minutes have elapsed under the assumption of exhaust gas leakage from the exhaust port connection part. At this time, the carbon dioxide concentration was 0.28%, and after 40 minutes, the oxygen was consumed, and it increased rapidly to 0.54%. Harmful gas such as nitric oxide was also measured in diesel combustion gas.

    

In the two igniters type portable butane burner, after about 30 minutes, the oxygen concentration dropped below the safe limit to 17.3%, and the carbon monoxide concentration steadily increased after 38 minutes, reaching 253ppm around 70 minutes after the experiment. The concentration of carbon monoxide continued to increase in the kerosene stove, and the value of 43 ppm was measured until about 35 minutes from the start of the experiment, and the oxygen level decreased to 17.7% after 10 minutes and to 14.7% after 50 minutes.

    

Seo Yong-Soo, a researcher who oversees experimental analysis and measurement at the Central Laboratory at Pukyong National University, said, "Charcoal increases carbon monoxide sharply due to incomplete combustion, and parking heaters can cause oxygen shortage due to active combustion. The risk of carbon monoxide poisoning and asphyxiation is very high if you use a heating device in the tent even for a short time. <Pukyong Today>
