The research objective was the increase of efficien-cy of the assessment of technological risks of electrical facilities. The efficiency was defined by offered method of the assessment of technological hazards of electrical facilities which considered temporal relationships of cause and effect between risk forming factors. For the accounting of temporal relationships of cause and effect between risk forming factors it was offered to use unary temporal operations "always in the past", "ever in the past" and binary indistinct operation "priority I". The software in the С# programming language was devel-oped for the calculation of technological hazards of elec-trical installations for the offered method. Using devel-oped software the assessment of risk of technogenic danger "electrical installation accident" on the object of JSC ‘Network company Altaykrayenergo’ in 2017 was carried out. As a result of research the value of techno-genic risk of danger "electrical installation accident" tak-ing into account temporal relationships of cause and effect between risk forming factors, equal 0.0014 was received. Received number means the frequency of considered event in a year. It is admissible risk accord-ing to the specifications and technical documentation. Also the assessment of technogenic risk of danger "electrical installation accident" without temporal rela-tionships of cause and effect between risk forming fac-tors was carried out, the risk equal 0.000015 was re-ceived (the acceptable risk). The analysis of electrical facilities of considered production object which was car-ried out in 2017 confirmed the existence of accidents. Offered temporal and indistinct method gives estimates of technological hazards of electrical installations more adequate way of calculation of risks of technogenic dangers of production object in comparison with the methods of the assessment of technological risks of electrical installations which are not considering tem-poral dependences between risk forming factors.
