摘要
[目的]以"风险体积"概括和展现危险源风险构成的整体性,探索破解危险源风险的理论途径。[方法]从经典风险理论,导出"风险体积"的概念,对危险源存在的事故风险进行三维分析,界定出危险源风险与隐患,体现从危险源到隐患再到风险的溯源关系。[结果]提出"一元隐患"、"二元隐患"和"三元风险"的观点。[结论]对于风险体积(三元风险),可通过降低(或消除)其中一种构成因素,使其缩小(或为零),事故风险下降(或消失)。
[Objective]The components of hazard source risks were summarized and revealed by use of ＂risk volume＇and theoretical methods were explored to avoid hazard source risks. [Methods]The concept of ＂risk volume＂ derived from classical risk theories was employed to conduct a three-dimensional analysis of accident risks from hazard source, it determined the risks and potential hazards from hazard sources and displaying the traceability from hazard sources to potential hazards and to risks. [ Results ] ＂unitary potential hazard＂ , ＂binary potential hazard＂ and ＂ternary risk＂ were put forward. [Conclusion ] Accident risks can be lowered or eliminated by reducing or removing one of the three components of risk volumes.
