ABSTRACT
The scenario concerning the exceptional blast load was based on the assumption of an explosion in the adjacent refinery causing a blast wave with a free field pressure of 15 kN/m2 and duration of 200 ms (Figure 3a). Additionally the reflection coef ficients depending on the angle of incidence had to be taken into account (Figure 3b). The reflection coefficient for the front and side wall (angle of inci dence approx. 45°) was estimated to 2 resulting in a peak surface pressure of 30 kN/m2.
