Abstract:

The Department of Defense Explosives Safety Board DDESB is conducting a continuing program to evaluate the fragment hazards produced by the accidental detonation of stored munitions. In support of this effort, the Naval Surface Weapons Center was found to conduct the Fragment Hazard Investigation Program. The purpose of the program is to provide the DDESB with fragmentation data to improve or to substantiate the quantity-distance QD standards for the safe and efficient storage of stacked munitions. The current program uses near- field fragment characterization data in conjunction with far-field collection data to predict far-field fragment density. The ultimate goal is to provide a methodology for the determination of QD standards for all hazard classifications. The hazard classification under investigation in this paper is the Mass-Detonating Hazard Materials Class 1, Division 1. The major effort of this program to date has been focused on the mass-detonating Army M107 155mm TNT loaded projectile. Close-in arena and far-field collection tests of various projectile and pallet stacking configurations have been conducted concurrent with supporting analytical studies. Fragmentation data were generated on projectile clusters which simultaneously detonate and on those which detonate by means of natural communication. Far-field collection tests were conducted on large stacks up to 36 pallets of at the White Sands Missile Range. A methodology was developed based on the entire set of test data which accurately predicted the total far-field fragment density.
