  • According to the study and experiments performed on the Improvement of Maintaining Temperature of Aviation Dangerous Goods, a conclusion was drawn that clear technical guidelines should be established from the design and assembly stage of temperature-controlled packaging, taking into account actual transportation environment. In particular, profiles consisting of only two types of summer and winter are difficult to adjust flexibly in transportation process with severe weather and temperature changes such as spring and fall. To this end, there is a need to establish a compromise profile configuration for summer and winter. It was also found that the condition of the refrigerant, temperature control, and the speed of the packaging operation have a significant impact on maintaining constant temperature. Therefore, all packing operations need to be completed within a short period of time in the environment close to the target temperature. The current packing instructions provided by packaging manufacturers do not provide precise instructions on post-conditioning, but the experiments in this study confirmed that post-conditioning is very important for maintaining the target temperature, so it is necessary to provide precise legal packing technical instructions.

  • 현대사회의 산업발전과 새로운 기술개발로 다양한 화학제품이 생산되어 인류생활을 윤택하게 하였지만 일부 화학물질은 국민의 안전과 환경에 많은 위험을 주고 있으며, 이들의 운송, 저장, 취급 등의 안전관리 문제가 대두되고 있는 실정이다. 특히, 도로운송 위험물은 사고빈도가 높아서 체계적인 안전관리시스템이 필요하다. 따라서 본 연구에서는 국내 운송위험물의 현황, 관련법 및 문제점을 파악하고, 국제운송위험물규칙(UN-RTDG)과 비교 검토하여 선진화된 안전관리 정책제언과 도로운송 위험물 분류표준화 방안 및 통일된 운송위험물 표시를 제시하였다. 이와 같은 선진화된 위험물질 안전관리에 의해 사고예방 및 대응을 최적화하여 인류의 건강과 환경보호에 기여할 것이다.

  • After the Tianjin Port explosion on 2015, it is highlighted that securing safety for dangerous goods in Korea and try to establish safety standards for railroad dangerous substances transport. In Korea, the regulation for the transport of dangerous goods is stipulated to need 3 buffer cars. However, It is inefficient that 3 buffer cars. because 3 buffer cars, increase transportation too much costs in transit and it is too strict compared to other country rules. The purpose of this study was to improve transportation efficiency by mitigating the criteria for isolated railroads through rational safety assessment. In order to verify this, we used a risk assessment software which is PHAST 7.2 developed by DNV GL. We calculated safety distances that could prevent ignitions setting up scenarios when relief system work installed on a train loaded with propylene, nonane. As a result, we confirmed that buffer cars can be reduced from three to one. This result would be implemented in the application of Korail.

  • Now a days, according to the increasing transportation of dangerous goods using cargo vessels, importance of the safe marine transportation also being issued. For this reason, the computerized IMDG Code was sincerely required. This paper shows stowage and segregation method of dangerous goods at marine transportation and general requirement of IMDG code and relationship between IMDG code and EMS / MFAG. And then draw up plan for making computerized IMDG Code on the basis of these requirements.
