HAZX Part 1. An Explosives Hazard Assessment Tool

Abstract

HAZX is an explosives safety software tool that can be used to assess the hazards and/or risks when Quantity-Distance (Q-D) safe separation distances are violated. Part 1 of the presentation focuses on the HAZX hazard module which includes a GUI/GIS interface to simplify user inputs, spatial analyses and the display of results and reports. The risk tool is being developed using alternative methods to the algorithms and methods documented in DDESB's Technical Paper No. 14. The underlying fragmentation model performs multiple simulations of drag-corrected fragment throw to account for uncertainties in their characteristics and automate the pseudo-trajectory normal method to compute hazardous fragment density considering 3D bounce/roll other uneven terrain. The hazard tools have been used to support equivalent protection and consequence explosion analyses launch vehicles and conventional weapons by the AF, FAA and Army. The HAZX hazard tool is demonstrated including the capability to compute: a) air blast and hazardous fragment density, and b) consequences of air blast and fragment impacts to ES's (damage, injury and fatality).
