Design of Barricades to Prevent Prompt Propagation
Abstract
Current requirements for determining the height of a barricade between two ammunition and explosives (AE) stacks are detailed in paragraph C5.3.2.3.2 of DoD 6055.9-STD, DoD Ammunition and Explosives Safety Standards . Two factors of these requirements (i.e. establishing the reference point at the far edge of the stack and drawing a line 2 degrees above the line of sight from the reference point to the other stack) are causing construction and operational challenges due to the required height of the barricade for large stacks of AE. This paper discusses some of the history of these requirements and proposed changes to these requirements. The fragmentation from stacks of munitions and the interaction zones resulting from detonation of stacks of munitions are discussed. Fragment trajectories and the impact of various barricade heights in mitigating fragments that can cause prompt propagation are presented. This paper details a proposal for changing the requirements for determining the height of a barricade between two AE stacks. An example of an open storage area using both the current requirements for the barricades and the proposed requirements is shown. As the example will show, the proposed changes will result in significant savings without sacrificing safety.
