The purpose of this study is to introduce a safety engineering approach (preventive approach) to environmental problems. Fault Tree Analysis (FTA) is adopted for this purpose. FTA is used to describe the structure of environmental disruption in this study. In other words, FTA is used as the method to describe environmental disruption itself.
Various types of approach have been attempted to solve environmental problems, but most of them seem to be symptomatic treatment. For instance, a system engineering approach, being expected to be an effective approach, is used to control environmental pollut ion or to abate it. It is thought that the systems engineering approach is not effecive in preventing an enviromental disruption. The necessity of anticipatory environmental policies being the same as preventive approaches is pointed out. The OECD Environmental Committee declared the necessity of anticipatory environmental policies. In the existing circumstance, the preventive approach to environmental disruption has not been tried as much. Therefore the preventive approach, fault tree analysis of environmental disruption, is attempted in this study.
