关于风险的理解 为了使风险这个事情十分具体,必须这样理解。 理解的前提条件: 事故可能的原因 、 事故本身 、 事故的后果都理解为事件 event ; 事故可能的原因就是危险源 hazard ; Hazard 的实质也是事件 event ; 风险是危险源 hazard 或者事件event 的风险。 理解风险: 危险源的危险程度,是事故发生的可能性与后果严重性的组合。 参看 45001 ( draft )的定义: Risk : effect of uncertainty Note 1 to entry: An effect is a deviation from theexpected — positive or negative. Note 2 to entry: Uncertainty is the state, evenpartial, of deficiency of information related to, understanding or knowledge of, an event, its consequence,or likelihood. Note 3 to entry: Risk is often characterized byreference to potential events (as definedin ISO Guide 73:2009,3.5.1.3) and consequences (as defined in ISOGuide 73:2009, 3.6.1.3), or a combination of these. Note 4 to entry: Risk is often expressed in terms ofa combination of the consequences ofan event (including changes in circumstances) and the associatedlikelihood (as defined in ISO Guide 73:2009, 3.6.1.1) ofoccurrence. 脱离危险源 hazard, 就无从谈起风险。 如果再理解一下 ISO Guide73:2009 , Risk management-Vocabulary , 就更有意思了: 我只摘录了几句,读者可自己浏览: Hazard can be a risk source (识别风险就要先识别危险源,再计算、分析得到其风险值,也就是说风险是危险源的风险) Hazard issource of potential harm (危险源本身就有隐藏、隐患的意思,也就是隐患) A risk source can be tangible or intangible (只识别物理危险源只是危险源的九牛之一毛。) . 关键词:风险,理解 45001
