A procedure is presented for assessing the quality of safety management. It is based on a set of questions concerning areas of relevance which have to be answered with value statements. Since such statements are vague, they are represented by fuzzy numbers. Hence they can be combined mathematically to judge the quality of management on the whole as well as that of the different areas considered. In this way weaknesses can be identified. The procedure was applied to a hazardous installation allowing a pertinent evaluation to be made within a tolerable amount of time. It is considered to have potential for replacing some of the safety analysis and auditing procedures currently in use.
