Hazard Analysis of Pollution Abatement Techniques. Volume III. (Appendix) Logic Model.

摘要

Volume III of this report contains Logic Models for the four systems analyzed in Volume I (Appendix to Volume I). The logic model begins with the top undesired event 'Fire or explosion results in equipment damage or personnel death or injury, 'and proceeds backwards through logical steps (gates) until it reaches the feedpoints; e.g., TNT from floor washings entering floor drains. By constructing the model in this manner, each component of the system can be evaluated separately in terms of the immediate causes that would contribute to the failure of the components. This technique results in an in-depth systems failure logic that is extremely comprehensive and provides an accurate account of all credible failures. The logic models developed in this study was generalized such that any hazardous material can be considered. This would minimize the time spent for analyzing a new system.
