This paper examines the ignition and combustion properties of HD1.3 substances and their influence on the thermally driven hazard threat. Materials that are easier to ignite and burn readily at low pressure are most vulnerable to the thermal threat. The surface area of the energetic material plays a strong role in the pressurization rate and subsequent reaction response of the energetic material. A series of subscale combustions tests in a concrete structure are being used to further examine the hazard response of an HD1.3 substance, to a combustion driven stimulus.
