At paper modeling of the occurrence periodicity of fires on vertical stainless tanks for contain oil and petroleum products from auto-ignition of pyrophoric deposits is given. The statistics on fires in tanks for contain oil and petroleum products from auto-ignition of pyrophoric deposits and distribution of fires by months from 2000 to 2016 are presented. Data are given about the period of the most frequent occurrence of fires in oil tank from the spontaneous combustion of pyrophoric deposits after the elimination of the previous fire in the oil tank for the same reason.
