This report summarizes the data collected as a result of the analyses of an explosion that occurred in a propellant development laboratory. The explosion occurred while the operators were weighing out some of the ingredients so that they could be compounded into an ultrahigh-burning-rate solid propellant. The post-accident investigation concluded that there was no evidence that the explosion had resulted from an error wherein the DANP was mixed with an incompatible material, but it was not possible to positively identify what was actually responsible for initiating the detonation. Several scenarios were postulated that might have been the cause, the most probable of which was that the bottle containing the DANP had been knocked over, and this shock had caused the DANP to detonate.
