Abstract: The invention relates to the use of a concentrated steeping liquor from the starch industry, referred to as corn steep, as a means for controlling the risks of fire caused by self-heating and the risks of explosion of dust caused by the particles and microparticles contained in the inflammable organic materials from the extractive industry, as well as by explosive gases released during the self-heating process during the storage, transport, and/or handling thereof. The concentrated steeping liquor of the invention is diluted with water and mixed with the material to be treated in respective proportions so as to obtain, for an index P up to 315 ?m, a percentage of fines at most equal to 6%.
