ABSTRACT: Initiation of fireworks articles, as by a fire, can result in communication to adjacent articles and at times transition to a mass explosion. Such an event can be catastrophic. In a quest to discover the process by which this transition occurs and thereby work to mitigate it so as to prevent the dire consequences, a series of research programs was established. This paper reports the findings of attempts to cause communication within a linear array of fireworks shells confined in steel pipes and to measure the shell-to-shell communication rate. The array of shells was initiated with an explosive booster charge. The findings indicate that such an array, with the given confinement and initiation stimulus, is not conducive to the sympathetic initiation of the tested fireworks shells.
