In work various options of development of fire-dangerous situations at oil spills depending on properties of soil systems are considered. Results of experiments on the permeability of soil deposits are interpreted from positions of the theory of percolation. For various types of soils, the border at a rate of granulometric fractions at which there comes the high-quality transition from a gel state in which the system has to be considered as a solid body to a freely permeable state in which oil products are in a type of liquid substance is experimentally established. Selective application of indicators of fire hazard for various types of soil structures is proved.
