This paper addresses the problem of designing the frangible panels in a row of cubicles for the blast load produced by an accidental explosion in a neighboring cubicle. This panel has to withstand the external load of the vented blast in order to maintain the protective function of the structure. To determine the load, a 3D hydrocode is used to obtain a numerical solution of the internal and external flow fields produced by an explosion in an adjoining cubicle. The calculation was carried out to 120 ms for a typical cubicle of 6.5x7.0x5.2 meters, assuming a charge of 24 kg. The results are compared with predictions obtained from commonly accepted design manuals.
