Abstract

Accidents associated with hazardous materials, including oil and HNS, in maritime transportation show increasing trend. Therefore, preventive countermeasures for such accidents should be provided. The purpose of this study is to analyze level of risk on human loss and potential damage to environment, using data on domestic marine accidents carrying hazardous materials (2002~2014), and identify high-risk accident types for urgent risk management which needs findings of accident causes and proper mitigation measures. High-risks on human loss are explosion and suffocation, occurred in process of ship maintenance and tank cleaning. On the other hand, high-risk on environmental damage is spill caused by ship accidents (collision, grounding and etc.). Especially, spill occurs during loading operation of oil and HNS onboard a ship. Strict operation supervision/management and safety education/training on a regular basis could prevent accidents, because human factors such as not wearing safety gear and careless cargo handling cause most of the marine accidents.

유류와 위험 유해물질(Hazardous and Noxious Substances, 이하 HNS)을 포함하는 위험물질의 해상운송 중에 발생하는 사고가 증가하고 있어, 이러한 위험물질 해양사고를 방지할 수 있는 예방대책을 마련해야 할 것이다. 이를 위해 국내에서 발생하는 위험물질 해양사고 자료(2002~2014)를 수집하여 인명 및 환경 위험도를 분석하였으며, 사고원인 규명 및 적절한 예방대책이 필요한 우선 안전관리분야를 파악하고자 하였다. 인명위험도는 선박 수리 및 탱커세정(tank cleaning) 작업과정에서 발생하는 폭발 및 인명사고 중 질식 등이 높은 것으로 분석되었다. 환경위험도는 충돌, 좌초 등에 의한 유출사고로 인해 발생하였다. 또한 비포장 상태의 위험화물을 선박에 적재 중 취급부주의로 인하여 유출사고가 일어났다. 다수의 사고는 적합한 안전장비 미착용, 취급 부주의 등 인적오류로 인한 사고로서 관리 감독을 강화하고, 주기적인 교육 훈련을 통하여 사고 저감이 가능하다. 위험물질 해양사고를 예방하기 위해서는 물질 자체 고유의 특성상 유해성과 위험성을 지닌 위험물질(유류와 HNS)에 대한 안전관리를 더욱 강화해야 한다.
