Abstract : Quantity-Distances for HD 1.3 explosives, particularly bulk gun propellants, are considered to be less soundly based than for HD 1.1 (mass exploding) and HD 1.2 explosives. Blast effects and projection hazards have been extensively studied and are comparatively well understood. The behaviour in a fire of bulk stocks, or loads, of HD 1.3 explosives depends primarily on the strength of the confining structure. Tests on tonnage quantities of boxed gun propellants in representative structures are reported. The unexpectedly energetic behaviour displayed indicates that existing Q-Ds for HD 1.3 explosives may give inadequate levels of protection. The orientation of entrances to propellant magazines may be a crucial element in the protection against communication between magazines and process buildings.
