Conditions of fire and explosion safety at a determination of permissible parameters for an operation of industrial facilities are considered. Relationships were obtained which describe a dependence of safe values of the parameters at an established probability of an occurrence of an unfavorable event (that is hazardous event with fire or explosion characterizing by an inadmissible risk level). The proposed method was tested on the basis of calculations of a probability of a successful evacuation from buildings and constructions in the case of a fire and safety coefficients to fire and explosion hazard indexes of substances and materials.
conditions of fire and explosion safety, permissible parameters for an operation of industrial facilities, fire risk, evacuation, safety coefficients.
