The probability of an initiating event (gas leakage) is assumed to be one. Relative probabilities of emergency situations are determined by analyzing statistical data on gas pipeline accidents at sub-zero ambient temperatures and by the likelihood of dangerous meteorological conditions. 4. Conclusion Thus, increase in industrial safety of hazardous objects in the conditions of the Arctic demands comprehensive account of climatic factors, specific to this area, on risk parameters. Risk assessment of accidents in hazardous objects for the Arctic zone on the basis of criteria of acceptable risk will allow to estimate dangers with unacceptable risk level and will form a basis for development of recommendations and measures for reduction of dangers in the conditions of severe climate of the Arctic.
