Modern methods and means of detecting fire at outside a potentially hazardous facility have been analyzed. The detection of an emergency situation as a result of the fire by the physical factors accompanying the combustion processes was considered. The main factors of the combustion process have been considered. Occurrence of initiating factors of hazard into two groups: internal, where factors of anthropogenic origin are dominant and external, where factors of natural origin are dominant is proposed to divide. A mathematical model for the prevention of emergencies resulting from a fire at potentially hazardous objects in order to prevent their spread and escalate to more significant levels of development, as well as to reduce false alarms of safety devices. Dominant external fire hazards have been identified. The mathematical model which consist system of the equations has been described. These determine the dependence of the acoustic spectrum emergency seat of fire outside a potentially hazardous facility and temporary phases of growth consequences. It is the task of placing the means of control and formation of acoustic images and fractional fractal dimension of hazard and comparing the latter with the acoustic loads of the technological process of functioning potentially hazardous facility. An effective emergency detection as a result of the fire based on its conditions of use has been determined. Further areas of research aimed at preventing emergencies from fire at potentially hazardous sites have been proposed. This is achieved through the development and application of new engineering techniques that build on the capabilities of current acoustic radiation control technologies of the hazard seat. A methodology for the formation of acoustic hazard images and comparing the latter with acoustic images of the technological process of the operation potentially dangerous object has been proposed.
