1991년 6월 신규 계면활성제 [a-SF]의 제조 공정의 하나인 메탄올 정류탑에 있어서 폭발사고가 발생했다. 폭발 형태는『폭굉』 이였다 라고 판단되어지고 정류탑은 대파되었으며 탑벽 파편은 대강 900m 범위로 비산되었고 사망자 2명, 부상자 13명의 피해를 입었다. 원인물질은 계면활성제의 표백으로 사용하는 메탄올과 과산화수소에 의해 미량 생성한 유기과산화물(Metal Hydroperoxide)에서 정류탑의 운전정지과정 중에 공급액의 부터 수십까지 국부적으로 농축되어져 열 폭발을 일으킨 것으로 추정 되어진다.

While products are storaged in a warehouse and delivered from it, human activities always are concerned with the work. So human errors can be occured in handling these jobs. This paper classified these human errors into 7 error types. Root causes of the 7 human error types are analyzed respectively and reasonalbe countermeasures are suggested to them. Therefore this research is expected to play an important role as a guideline in the fields relating to human activities.

In the June, 1991, there was the explosion in which methanol rectified column as a part of the new surface active agent's manufacturing processes. The type of explosion was estimated as the 'detonation'. The methanol rectified column was ruined, and broken pieces of the column were scattered within 900m. Also, there were victims such as the two deads and thirteen wounded persons. The cause of the explosion was heat explosion by being concentrated locally from 0.1% to several tens% of supply fluid at Metal Hydroperoxide, which was produced by methanol and hydrogen peroxide used as the bleach of surface active agent, during the operation stoppage process of methanol rectified column.

Logistics is one of the most important factors to manage a stream of materials in economic environment. Establishing effective logistics system needs to consider some constraints which are fluctuation of materials volume, a long distance between makers and consumers, one way logistics and small quantity batch production. It is estimated that Unit Load System should be a powerful method to cope with those problems. It helps to realize the key issues which are Standardization and Logistics Pool System The Material Unification of Logistics System is able to participate in all kinds of industries including manufacturing, distribution and logistics. This system has some merits which are a long distance transportation cost down, product recovery, and treatment in the unbalance of demand and supply caused by unstable materials volume. Four strategies of Material Logistics Model are Packing Rationalization, Logistics Pool System, JIT System application and establishing effective infrastructure. The Material Unification Of Logistics System based on Unit Load System achieves efficiency of logistics and largely decreases moving cost.
