Abstract : Steady-state thermal explosion theory was used to predict safe storage and transportation (critical) masses at a series of temperatures for three representative types of self-heating materials--baled wool, powdered ammonium nitrate and a solution of methylethyl ketone (2-butanone) peroxide (40%) in dimethyl phthalate. The non-steady-state theory (reactant consumption admitted) was used to estimate the time taken for these critical masses to reach the critical state at each temperature. The critical masses are shown to be consistent with safety requirements at present accepted for the storage and transportation of the materials discussed. The estimates of the times taken by the critical masses to reach the critical state bring an added dimension to the critical mass calculations, and together these results constitute an advance over the present situation where safe limits have been deduced on a trial and error basis. The methods outlined may be used to estimate critical masses and induction periods for any other self-heating material and may be relied upon to give results of the correct order of magnitude.
