Introduction: Brazilian electricity sector is one of the leaders in fatal work accidents. Total accidents number between 1999 and 2013, for instance, is 4.8 times bigger than those of other formal sectors of economy in Brazil. Technology systems and work organization in this sector are complex, and work conditions are dangerous, frequently resulting in work accidents. Objective: To analyze the influence of managerial and organizational choices at the Brazilian electricity sector on work safety. Method: series of cases study based on interviews and focal groups with key role-players, documental analysis and work observation, as well as reanalysis of work accidents in the distribution sector guided by concepts adopted in the method Accidents Analysis and Prevention Model (MAPA). Results: Interviews indicate that, in the electricity sector, economy is guided by financial logic of very short time results and that outsourcing is one of the guiding lines of job insecurity. Variability analysis showed flaws in human resources management by allowing the employment of subcontractors which were not protected, from the cognitive point of view, in order to carry out maintenance work in electrified environment. In all cases, the barrier analysis showed that safety management did not highlight interventions in the vicinity of energized primary line (high voltage) as being a potentially risky or dangerous situation. Changes analysis indicated the contribution of flaws in materials management and maintenance for the accidents, also influenced by quality and performance assessment adopted by the National Regulatory Authority, which determine uninterrupted power supply at the expense of safety. Discussion: The interviews of trade union leaders, as well as the cases analysis, indicated a weakening process of workers communities, which result in dilution and devaluation of practical knowledge and experiences. This study offers technical and organizational ...
