Manufacturing, storage, transportation and practical application of energetic materials, particularly high explosives (HE) are tightly connected with the danger of accidental explosion. The real cause of the explosion can be different, e.g. impact, friction, self-heating, influence of a shock wave, radiation, electrical discharge, etc. However, the first stage or the first link of the chain of ... [Show full abstract] events (called lately Bowden’s chain ) leading to energy evolution which results in destruction and demolition of the environment is always combustion of HE. Correspondingly, every accidental explosion in some sense might be considered as a consequence of a fire. However, the aim of this paper is to analyze only those accidents where explosion can be considered as a result of more or less prolonged influence of a fire on the relatively big amounts of HE.
