The possibility of using rupture discs to quench the incipient combustion of emulsion explosives in a confined chamber was demonstrated experimentally. A mathematical model is presented which predicts the pressure build‐up due to combustion of explosive initiated from a small local source and the subsequent pressure release due to the opening of the rupture disc. The model successfully reproduces almost exactly the pressure records obtained from experiments on typical emulsion explosives and on sodium‐perchlorate sensitized emulsion explosives burning in a simulated emulsion pump equipped with a rupture disc.
