Scales of consequences of accidents depend on the sizes of the cloud of the infected air and quality of resource management which arose when corruptings and spreaded in the atmosphere on mitigation of consequences. The purpose of operational management of resources on mitigation of consequences in alert conditions in case of release of ecologically dangerous substances are a minimization of spatial boundaries of manifestation of the striking action of a cloud of the infected air. In environmental monitoring of a status of dangerous chemical production the possibility of tracing in real time of consequences of burst of toxic agent is of great importance. Therefore an opportunity to trace a path of relocation of an aerosol cloud in real time is represented important. In article need of use of the distributed computing systems for mathematical process modeling of formation of a cloud of the infected air in case of origin of beyond design basis alert conditions on technogenic chemical and technological objects is justified. Classification of the considered alert conditions depending on the factors generating them is given. Processes of formation of a cloud of the infected air as control objects are considered. Dependence of speed of change of concentration of dangerous impurity in arbitrary point of space is analyzed and mathematical models of processes of formation of a cloud of the infected air in case of high-temperature bursts (explosions, the fires) and passages of large amounts of toxic chemicals on different surfaces with their subsequent evaporation are given. Feasibility of decomposition of the task of process modeling of formation of a cloud of the infected air is proved.
