An international comparison of four quantitative risk assessment approaches : Benchmark study based on a fictitious LPG plant

Een internationale vergelijking van vier kwantitatieve risicoanalyse methoden : Benchmark studie op basis van een fictief lpg-bedrijf

Synopsis

The methods to determine external safety risks used in the United Kingdom, France, the Walloon Region of Belgium and the Netherlands are very different. The differences concern both the way the calculations are performed and the consequences calculated (such as deaths or health damage to persons). Despite the differences, the methods yield similar results in terms of the safety distances.

This conclusion can be drawn from a benchmark study of a fictitious LPG storage plant performed by experts of these countries. However, similar results can lead to different policy implications. For instance, the safety distances in the Netherlands and France are used as limit values, whereas in Belgium and the United Kingdom they are used as guide values.
