摘要：Organizational accidents have occurred repeatedly in Japan over the past several years. Most of these accidents seem to have been occurred within a gray zone between the safety zone and the danger zone rather than within the danger zone. The present paper considers "risk engineering" as engineering for preventing such accidents that occur within the gray zone, and proposes a framework for analyzing design methods of reducing the gray zone. Firstly, it asserts that safety management design should be classified into a safety-assurance design, and a danger-avoidance design and, that the danger-avoidance design method should incorporate two types of learning mechanism. Next, our paper shows two positive examples utilizing a gray zone for reducing risk ; one is a description method for operation manual or rules, and the other is a reliable safety monitoring design method.
