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 associated"likelihood" (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。).
