Resumo


The risks associated with working in the energy sector are: electrical risks, falls, and occupational risks. Describe the risks in the electricity sector, particularly through with data of an electric power company in Northeast Brazil. These data were acquired through accidents internal reporting which resulted in a total of 546 events. Variables such as worker age, day of week, month, and hour of occurrence were analyzed. In terms of worker age, the highest incidence of accidents (74%) occurs with more experienced workers in the company, specifically in those workers 41 to 60 years of age. An increase in the amount of days lost due to accident is related to an increase in the age of the worker. Using a statistical model the influence of worker age (WA) and working time (WT) in the behavior of the dependent variable of days absent (DA) were determined.
