Swiss risk assessment methods

Figure 37. Risk Matrix for Swiss Risk Assessment Methods. (Ref. 42)...

In Ref. 42, we see a review of the risk assessment methods used in Switzerland, and an application to assessing risks in solid propellant production. In the Swiss methods, one first defines individual risk r, as... 

The total risk assessment process used by the Swiss is shown in Fig. 38. In Switzerland, an acceptable individual risk has been established to be 3 x 10-/Vyear. It is interesting to note that this value is not far from that footnoted in Table VI, which converts to 10 3/year. But, methods of calculating probabilities in Refs. 41 and 42 are quite different.
