Assessment of risk factors for death in electrical injury.

Fatal high-voltage injuries present a problem which has not yet been studied sufficiently in the context of interaction between the human body and electricity, as a technical, anthropogenic and natural phenomenon. The forensic medicine records of 291 cases of death caused by high-voltage current for a 41-year-long period (1965-2006) were examined in retrospect. The descriptive statistical analyses were made using the SPSS 11.0 software. Death was found to result most commonly from contact between the deceased and elements of the power transmission and distribution grid: (41.24%), and from the action of lightning: (32.3%), the difference in their relative share being insignificant. Much more rarely, death was due to contact with construction and repair electrical devices: (7.56%), or with elements of the power transport railway infrastructure: (6.87%). Death resulting from contact with agricultural electrical devices was only occasional: (0.68%). The victims' average age was 36.19 years. Our analysis indicates that the relative share (43.98%) of the victims is the highest in the age period between 25 and 44. The ratio between women and men is 1:21.38.
