Assessment of Hazardous Areas When Storing HD 1.1 Ammunition in French Igloo Type Magazine

摘要

The French Army presently stores its ammunition inside 'Igloo type' magazines, the unit capacity of which is 60 metric tons. Within the framework of pyrotechnical safety, the S.T.B.F.T. was asked by the Army Staff to determine by tests the extent of the hazardous areas related to this type of storage and to compare the results to the quantity distances (Q - D) selected in the French regulations. The first phase of this test campaign, the subject of this paper, is only concerned with the assessment of Q - D related to blast effects (HD 1.1). Twenty-one scaled tests (1:3) were performed in earth covered steel arch igloos. Different arrangements were tested in order to determine the influence of various parameters. During the whole campaign, more than 300 blast pressure data were recorded, which enables to make an accurate comparison with the French regular Q-D and to add useful information to the numerous tests already performed in this area by other countries.
