THE USE OF HAZARD-WARNING ANALYSIS

The need to obtain a measure of safety assurance for process facilities with a high hazard potential has led to the idea of using certain mishaps or failures to get a measure of the remoteness of a major accident. These incidents of less impact serve as warnings. The definition and use of hazard-warning incides are discussed, as well as the robustness of the failure-event logic used in developing the hazard-warning structure. It is concluded that hazard-warning analysis has a place in safety assurance in both design and operation of process-plant facilities.
