Trials to Determine the Effects of the Accidental Ignition of Stacks of Hazard Division 1.2 Ammunition

摘要

To date, nearly all international effort in the field of accidental explosion consequence determination has been aimed at the quantification of the effects of a Hazard Division (HD) 1.1 event in an explosives storage facility. Until the commencement of the program of work described here, little attention has been paid to the consequences of the ignition of stacks of Hazard Division 1.2 ammunition either in or out of storehouses. In 1989 NATO AC/258 agreed that a program of trials should be carried out to investigate the consequences of an HD 1.2 event with the aim of revising the current NATO quantity-distance relationships and placing them on a firmer footing. The program of trials to investigate the effects of the initiation of 105mm TNT loaded ammunition stacked in the open was commenced in 1991. A report on the results obtained at the time was given at the 25th seminar and interim conclusions were drawn. The program of trials on the TNT loaded ammunition has now been completed and further analysis of the results carried out. The conclusions of the analysis are reported. At the same time, the need was identified to extend the database of effects to examine the consequences of changes in packaging, caliber and type of ammunition, and the explosive fill. The resulting program of trials is described and initial results for the first of these (examining the effects of changing from TNT to Composition B filling in 105mm ammunition) are reported.
